備註

Int32這是一個不可變的實值型別,代表帶正負號的整數,其值的範圍Int32.MinValue從負2147483648(由常數表示)到正 2147483647 Int32.MaxValue (以常數表示)。Int32 is an immutable value type that represents signed integers with values that range from negative 2,147,483,648 (which is represented by the Int32.MinValue constant) through positive 2,147,483,647 (which is represented by the Int32.MaxValue constant. .NET Framework 也包含不帶正負號的32位整數數值型別UInt32,這代表的值範圍從0到4294967295。The .NET Framework also includes an unsigned 32-bit integer value type, UInt32, which represents values that range from 0 to 4,294,967,295.

具現化 Int32 值Instantiating an Int32 Value

您可以透過數Int32種方式將值具現化:You can instantiate an Int32 value in several ways:

  • 您可以Int32宣告變數,並為其指派在Int32資料類型範圍內的常值整數值。You can declare an Int32 variable and assign it a literal integer value that is within the range of the Int32 data type. 下列範例會宣告兩Int32個變數,並以這種方式為其指派值。The following example declares two Int32 variables and assigns them values in this way.

    int number1 = 64301;
    int number2 = 25548612;
    
    Dim number1 As Integer = 64301
    Dim number2 As Integer = 25548612
    
  • 您可以指派整數類型的值,其範圍是Int32類型的子集。You can assign the value of an integer type whose range is a subset of the Int32 type. 這是擴輾轉換,不需要中C#的轉換運算子或 Visual Basic 中的轉換方法。This is a widening conversion that does not require a cast operator in C# or a conversion method in Visual Basic.

    sbyte value1 = 124;
    short value2 = 1618;
    
    int number1 = value1;
    int number2 = value2;
    
    Dim value1 As SByte = 124
    Dim value2 As Int16 = 1618
    
    Dim number1 As Integer = value1
    Dim number2 As Integer = value2
    
  • 您可以指派數數值型別的值, Int32其範圍超出類型的範圍。You can assign the value of a numeric type whose range exceeds that of the Int32 type. 這是一個縮小轉換,因此,它需要中C#的 cast 運算子和 Visual Basic 中的轉換方法Option Strict (如果是 on)。This is a narrowing conversion, so it requires a cast operator in C# and a conversion method in Visual Basic if Option Strict is on. 如果數值是Single包含小陣列件的Double、或Decimal值,則處理其小數部分取決於執行轉換的編譯器。If the numeric value is a Single, Double, or Decimal value that includes a fractional component, the handling of its fractional part depends on the compiler performing the conversion. 下列範例會執行縮小轉換,將數個數值Int32指派給變數。The following example performs narrowing conversions to assign several numeric values to Int32 variables.

    long lNumber = 163245617;
    try {
       int number1 = (int) lNumber;
       Console.WriteLine(number1);
    }
    catch (OverflowException) {
       Console.WriteLine("{0} is out of range of an Int32.", lNumber);
    }
    
    double dbl2 = 35901.997;
    try {
       int number2 = (int) dbl2;
       Console.WriteLine(number2);
    }   
    catch (OverflowException) {
       Console.WriteLine("{0} is out of range of an Int32.", dbl2);
    }
       
    BigInteger bigNumber = 132451;
    try {
       int number3 = (int) bigNumber;
       Console.WriteLine(number3);
    }
    catch (OverflowException) {
       Console.WriteLine("{0} is out of range of an Int32.", bigNumber);
    }    
    // The example displays the following output:
    //       163245617
    //       35902
    //       132451
    
    Dim lNumber As Long = 163245617
    Try
       Dim number1 As Integer = CInt(lNumber)
       Console.WriteLine(number1)
    Catch e As OverflowException
       Console.WriteLine("{0} is out of range of an Int32.", lNumber)
    End Try
    
    Dim dbl2 As Double = 35901.997
    Try
       Dim number2 As Integer = CInt(dbl2)
       Console.WriteLine(number2)
    Catch e As OverflowException
       Console.WriteLine("{0} is out of range of an Int32.", dbl2)
    End Try
       
    Dim bigNumber As BigInteger = 132451
    Try
       Dim number3 As Integer = CInt(bigNumber)
       Console.WriteLine(number3)
    Catch e As OverflowException
       Console.WriteLine("{0} is out of range of an Int32.", bigNumber)
    End Try    
    ' The example displays the following output:
    '       163245617

    '       132451
    
  • 您可以呼叫Convert類別的方法,將任何支援的類型Int32轉換成值。You can call a method of the Convert class to convert any supported type to an Int32 value. 這是可能的Int32 IConvertible ,因為支援介面。This is possible because Int32 supports the IConvertible interface. 下列範例說明如何將Decimal值陣列轉換成Int32值。The following example illustrates the conversion of an array of Decimal values to Int32 values.

    decimal[] values= { Decimal.MinValue, -1034.23m, -12m, 0m, 147m,
                        199.55m, 9214.16m, Decimal.MaxValue };
    int result;
    
    foreach (decimal value in values)
    {
       try {
          result = Convert.ToInt32(value);
          Console.WriteLine("Converted the {0} value '{1}' to the {2} value {3}.",
                            value.GetType().Name, value,
                            result.GetType().Name, result);
       }
       catch (OverflowException) {
          Console.WriteLine("{0} is outside the range of the Int32 type.",
                            value);
       }   
    }                                  
    // The example displays the following output:
    //    -79228162514264337593543950335 is outside the range of the Int32 type.
    //    Converted the Decimal value '-1034.23' to the Int32 value -1034.
    //    Converted the Decimal value '-12' to the Int32 value -12.
    //    Converted the Decimal value '0' to the Int32 value 0.
    //    Converted the Decimal value '147' to the Int32 value 147.
    //    Converted the Decimal value '199.55' to the Int32 value 200.
    //    Converted the Decimal value '9214.16' to the Int32 value 9214.
    //    79228162514264337593543950335 is outside the range of the Int32 type.
    
    Dim values() As Decimal = { Decimal.MinValue, -1034.23d, -12d, 0d, 147d, _
                                199.55d, 9214.16d, Decimal.MaxValue }
    Dim result As Integer
    
    For Each value As Decimal In values
       Try
          result = Convert.ToInt32(value)
          Console.WriteLine("Converted the {0} value '{1}' to the {2} value {3}.", _
                            value.GetType().Name, value, _
                            result.GetType().Name, result)
       Catch e As OverflowException
          Console.WriteLine("{0} is outside the range of the Int32 type.", _
                            value)
       End Try   
    Next                                  
    ' The example displays the following output:

    '    79228162514264337593543950335 is outside the range of the Int32 type.
    
  • 您可以呼叫ParseTryParse方法,將Int32Int32的字串表示轉換成。You can call the Parse or TryParse method to convert the string representation of an Int32 value to an Int32. 字串可以包含十進位或十六進位數位。The string can contain either decimal or hexadecimal digits. 下列範例說明使用十進位和十六進位字串的剖析作業。The following example illustrates the parse operation by using both a decimal and a hexadecimal string.

    string string1 = "244681";
    try {
       int number1 = Int32.Parse(string1);
       Console.WriteLine(number1);
    }
    catch (OverflowException) {
       Console.WriteLine("'{0}' is out of range of a 32-bit integer.", string1);
    }
    catch (FormatException) {
       Console.WriteLine("The format of '{0}' is invalid.", string1);
    }
    
    string string2 = "F9A3C";
    try {
       int number2 = Int32.Parse(string2,
                                System.Globalization.NumberStyles.HexNumber);
       Console.WriteLine(number2);
    }
    catch (OverflowException) {
       Console.WriteLine("'{0}' is out of range of a 32-bit integer.", string2);
    }
    catch (FormatException) {
       Console.WriteLine("The format of '{0}' is invalid.", string2);
    }
    // The example displays the following output:
    //       244681
    //       1022524
    
    Dim string1 As String = "244681"
    Try
       Dim number1 As Integer = Int32.Parse(string1)
       Console.WriteLine(number1)
    Catch e As OverflowException
       Console.WriteLine("'{0}' is out of range of a 32-bit integer.", string1)
    Catch e As FormatException
       Console.WriteLine("The format of '{0}' is invalid.", string1)
    End Try
    
    Dim string2 As String = "F9A3C"

在 Int32 值上執行運算Performing Operations on Int32 Values

Int32型別支援標準的數學運算,例如加法、減法、除法、乘法、負和一元否定。The Int32 type supports standard mathematical operations such as addition, subtraction, division, multiplication, negation, and unary negation. 與其他整數類資料類型一樣Int32 ,此類型也支援ANDORXOR、、左移位和右移位運算子。Like the other integral types, the Int32 type also supports the bitwise AND, OR, XOR, left shift, and right shift operators.

您可以使用標準數值運算子來比較兩個Int32值,也可以CompareTo呼叫或Equals方法。You can use the standard numeric operators to compare two Int32 values, or you can call the CompareTo or Equals method.

您也可以呼叫Math類別的成員來執行廣泛的數值作業,包括取得數位的絕對值、從整數除法計算商和餘數,判斷兩個的最大或最小值整數、取得數位的正負號,以及進位數位。You can also call the members of the Math class to perform a wide range of numeric operations, including getting the absolute value of a number, calculating the quotient and remainder from integral division, determining the maximum or minimum value of two integers, getting the sign of a number, and rounding a number.

將 Int32 表示為字串Representing an Int32 as a String

Int32型別會提供標準和自訂數值格式字串的完整支援。The Int32 type provides full support for standard and custom numeric format strings. (如需詳細資訊,請參閱格式化類型標準數值格式字串自訂數值格式字串。)(For more information, see Formatting Types, Standard Numeric Format Strings, and Custom Numeric Format Strings.)

若要將Int32值格式化為沒有前置零的整數位符串,您可以呼叫無參數ToString()方法。To format an Int32 value as an integral string with no leading zeros, you can call the parameterless ToString() method. 藉由使用 "D" 格式規範,您也可以在字串表示中包含指定數目的前置零。By using the "D" format specifier, you can also include a specified number of leading zeros in the string representation. 藉由使用 "N" 格式規範,您可以包含群組分隔符號,並指定要在數位的字串表示中顯示的小數位數。By using the "N" format specifier, you can include group separators and specify the number of decimal digits to appear in the string representation of the number. 藉由使用 "X" 格式規範,您可以將Int32值表示為十六進位字串。By using the "X" format specifier, you can represent an Int32 value as a hexadecimal string. 下列範例會以這四種方式來格式化Int32值陣列中的元素。The following example formats the elements in an array of Int32 values in these four ways.

int[] numbers = { -1403, 0, 169, 1483104 };
foreach (int number in numbers) {
   // Display value using default formatting.
   Console.Write("{0,-8}  -->   ", number.ToString());
   // Display value with 3 digits and leading zeros.
   Console.Write("{0,11:D3}", number);
   // Display value with 1 decimal digit.
   Console.Write("{0,13:N1}", number);
   // Display value as hexadecimal.
   Console.Write("{0,12:X2}", number);
   // Display value with eight hexadecimal digits.
   Console.WriteLine("{0,14:X8}", number);
}   
// The example displays the following output:
//    -1403     -->         -1403     -1,403.0    FFFFFA85      FFFFFA85
//    0         -->           000          0.0          00      00000000
//    169       -->           169        169.0          A9      000000A9
//    1483104   -->       1483104  1,483,104.0      16A160      0016A160
Dim numbers() As Integer = { -1403, 0, 169, 1483104 }
For Each number As Integer In numbers
   ' Display value using default formatting.
   Console.Write("{0,-8}  -->   ", number.ToString())
   ' Display value with 3 digits and leading zeros.
   Console.Write("{0,11:D3}", number) 
   ' Display value with 1 decimal digit.
   Console.Write("{0,13:N1}", number) 
   ' Display value as hexadecimal.
   Console.Write("{0,12:X2}", number) 
   ' Display value with eight hexadecimal digits.
   Console.WriteLine("{0,14:X8}", number)
Next   
' The example displays the following output:
'    -1403     -->         -1403     -1,403.0    FFFFFA85      FFFFFA85
'    0         -->           000          0.0          00      00000000
'    169       -->           169        169.0          A9      000000A9

您也可以藉由Int32 ToString(Int32, Int32)呼叫方法並提供基底做為方法的第二個參數,將值格式化為二進位、八進位、十進位或十六進位字串。You can also format an Int32 value as a binary, octal, decimal, or hexadecimal string by calling the ToString(Int32, Int32) method and supplying the base as the method's second parameter. 下列範例會呼叫這個方法,以顯示整數值陣列的二進位、八進位和十六進位標記法。The following example calls this method to display the binary, octal, and hexadecimal representations of an array of integer values.

int[] numbers = { -146, 11043, 2781913 };
Console.WriteLine("{0,8}   {1,32}   {2,11}   {3,10}", 
                  "Value", "Binary", "Octal", "Hex");
foreach (int number in numbers) {
   Console.WriteLine("{0,8}   {1,32}   {2,11}   {3,10}", 
                     number, Convert.ToString(number, 2), 
                     Convert.ToString(number, 8), 
                     Convert.ToString(number, 16));
}      
// The example displays the following output:

使用非十進位32位整數值Working with Non-Decimal 32-Bit Integer Values

除了使用個別整數做為十進位值,您可能會想要使用整數值來執行位運算,或使用整數值的二進位或十六進位標記法。In addition to working with individual integers as decimal values, you may want to perform bitwise operations with integer values, or work with the binary or hexadecimal representations of integer values. Int32值會以31個位表示,並使用三十秒的位做為符號位。Int32 values are represented in 31 bits, with the thirty-second bit used as a sign bit. 正數值是使用正負號標記法來表示。Positive values are represented by using sign-and-magnitude representation. 負值是以兩補數表示。Negative values are in two's complement representation. 當您對Int32值執行位運算,或使用個別位時,請務必記住這一點。This is important to keep in mind when you perform bitwise operations on Int32 values or when you work with individual bits. 若要在任何兩個非十進位值上執行數值、布林值或比較運算,這兩個值都必須使用相同的標記法。In order to perform a numeric, Boolean, or comparison operation on any two non-decimal values, both values must use the same representation.
