注解

Int32 是表示一个不可变的值类型的有符号整数的值范围从负的 2,147,483,648 (这由Int32.MinValue常量) 2,147,483,647 之间 (表示通过Int32.MaxValue常量。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 还包括 32 位无符号的整数值类型, UInt32,它表示的范围介于 0 和 4,294,967,295 之间的值。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.

实例化一个 Int32 值Instantiating an Int32 Value

可以实例化Int32几种方式的值:You can instantiate an Int32 value in several ways:

  • 您可以声明Int32变量并将其分配的范围内的整数值Int32数据类型。You can declare an Int32 variable and assign it a literal integer value that is within the range of the Int32 data type. 下面的示例声明了两个Int32变量并将其分配这种方式中的值。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
    
  • 您可以将其范围是子集的整数类型的值分配的Int32类型。You can assign the value of an integer type whose range is a subset of the Int32 type. 这是不需要强制转换运算符在 C# 或 Visual Basic 中的转换方法的扩大转换。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
    
  • 可以分配的范围超过了数值类型的值的Int32类型。You can assign the value of a numeric type whose range exceeds that of the Int32 type. 这是收缩转换,因此它需要在 C# 中的强制转换运算符,并在 Visual Basic 中的转换方法如果Option Strict上。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. 如果使用数字值是SingleDouble,或Decimal包括小数部分,其小数部分处理的值取决于编译器执行转换。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. 下面的示例执行收缩转换,若要将分配到多个数值Int32变量。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
    '       35902
    '       132451
    
  • 您可以调用的方法Convert类来转换任何受支持的类型为Int32值。You can call a method of the Convert class to convert any supported type to an Int32 value. 这可能是因为Int32支持IConvertible接口。This is possible because Int32 supports the IConvertible interface. 下面的示例演示转换的数组Decimal值到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 }

          result = Convert.ToInt32(value)
          Console.WriteLine("Converted the {0} value '{1}' to the {2} value {3}.", _
                            value.GetType().Name, value, _

    Next                                  
    ' The example displays the following output:

  • 您可以调用ParseTryParse方法将转换的字符串表示形式Int32值设为Int32You can call the Parse or TryParse method to convert the string representation of an Int32 value to an Int32. 该字符串可包含十进制或十六进制数字。The string can contain either decimal or hexadecimal digits. 下面的示例说明了通过使用十进制和十六进制字符串的分析操作。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);
    }

    }
    
    string string2 = "F9A3C";
    try {
       int number2 = Int32.Parse(string2,
                                System.Globalization.NumberStyles.HexNumber);
       Console.WriteLine(number2);
    }
    catch (OverflowException) {

对 Int32 值执行操作Performing Operations on Int32 Values

Int32类型支持标准的数学运算,例如加法、 减法、 除法、 乘法、 求反和一元求反。The Int32 type supports standard mathematical operations such as addition, subtraction, division, multiplication, negation, and unary negation. 与其他整数类型,类似Int32类型还支持按位ANDORXOR,左移位和右移位运算符。Like the other integral types, the Int32 type also supports the bitwise AND, OR, XOR, left shift, and right shift operators.

可以使用标准数字运算符比较两个Int32值,也可以调用CompareToEquals方法。You can use the standard numeric operators to compare two Int32 values, or you can call the CompareTo or Equals method.

您还可以调用的成员Math类来执行各种数值操作,包括获得某个数字的商和整数除法运算的余数计算确定两个最大或最小值的绝对值整数,获取数字的符号和舍入数字。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.

作为一个字符串,表示为 int32 类型Representing an Int32 as a String

Int32类型提供对标准和自定义数字格式字符串的完全支持。The Int32 type provides full support for standard and custom numeric format strings. (有关详细信息,请参阅格式设置类型标准数字格式字符串,并自定义数字格式字符串。)(For more information, see Formatting Types, Standard Numeric Format Strings, and Custom Numeric Format Strings.)

若要设置格式Int32值作为不带前导零的整数字符串,可以调用无参数ToString()方法。To format an Int32 value as an integral string with no leading zeros, you can call the parameterless ToString() method. 通过使用"D"格式说明符,还可以包含指定的数目的字符串表示形式中的前导零。By using the "D" format specifier, you can also include a specified number of leading zeros in the string representation. 通过使用"N"格式说明符,可以包含组分隔符和指定的十进制位数出现在数字的字符串表示形式。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. 通过使用"X"格式说明符,可以表示Int32值作为十六进制字符串。By using the "X" format specifier, you can represent an Int32 value as a hexadecimal string. 下面的示例中的数组元素进行格式设置Int32以下四种方式中的值。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

此外可以设置格式Int32通过调用十进制或十六进制字符串值作为二进制、 八进制ToString(Int32, Int32)方法,并提供方法的第二个参数的基。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. 下面的示例调用此方法来显示二进制、 八进制和十六进制形式表示的整数值的数组。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));

处理非十进制 32 位整数值Working with Non-Decimal 32-Bit Integer Values

除了使用单个整数作为十进制值时,你可能想要执行按位运算的整数值,或使用整数值的二进制或十六进制表示形式。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 值以 31 位,计时的三十秒位用作符号位为单位表示。Int32 values are represented in 31 bits, with the thirty-second bit used as a sign bit. 使用符号数值表示法来表示正值。Positive values are represented by using sign-and-magnitude representation. 负值是以 2 的补数表示。Negative values are in two's complement representation. 这一点上执行按位运算时,需要注意Int32值或使用的单个位。This is important to keep in mind when you perform bitwise operations on Int32 values or when you work with individual bits. 若要执行数字、 布尔值或对任何两个非十进制值的比较运算,这两个值都必须使用相同的表示形式。In order to perform a numeric, Boolean, or comparison operation on any two non-decimal values, both values must use the same representation.
