Int16.MinValue 欄位

定義

代表 Int16 最小的可能值。Represents the smallest possible value of Int16. 這個欄位是常數。This field is constant.

public: short MinValue = -32768;
public const short MinValue = -32768;
val mutable MinValue : int16
Public Const MinValue As Short  = -32768

範例

下列範例會使用 MinValue 屬性,以防止 OverflowException 轉換成 Int16 值。The following example uses the MinValue property to prevent an OverflowException when converting to an Int16 value.

array<Int64>^ numbersToConvert = {162345, 32183, -54000};
Int16 newNumber;
for each (Int64 number in numbersToConvert)
{
   if (number >= Int16::MinValue && number <= Int16::MaxValue)
   {
      newNumber = Convert::ToInt16(number);
      Console::WriteLine("Successfully converted {0} to an Int16.", 
                         newNumber);
   }
   else
   {
      Console::WriteLine("Unable to convert {0} to an Int16.", number);
   }
}
// The example displays the following output:
//       Unable to convert 162345 to an Int16.
//       Successfully converted 32183 to an Int16.
//       Unable to convert -54000 to an Int16.   
long[] numbersToConvert = {162345, 32183, -54000};
short newNumber;
foreach (long number in numbersToConvert)
{
   if (number >= Int16.MinValue && number <= Int16.MaxValue)
   {
      newNumber = Convert.ToInt16(number);
      Console.WriteLine("Successfully converted {0} to an Int16.", 
                        newNumber);
   }
   else
   {
      Console.WriteLine("Unable to convert {0} to an Int16.", number);
   }
}
// The example displays the following output to the console:
//       Unable to convert 162345 to an Int16.
//       Successfully converted 32183 to an Int16.
//       Unable to convert -54000 to an Int16.   
Dim numbersToConvert() As Long = {162345, 32183, -54000}
Dim newNumber As Int16
For Each number As Long In NumbersToConvert
   If number >= Int16.MinValue And number <= Int16.MaxValue Then
      newNumber = Convert.ToInt16(number)
      Console.WriteLine("Successfully converted {0} to an Int16.", _
                        newNumber)
   Else
      Console.WriteLine("Unable to convert {0} to an Int16.", number)
   End If                     
Next
' The example displays the following output to the console:
'       Unable to convert 162345 to an Int16.
'       Successfully converted 32183 to an Int16.
'       Unable to convert -54000 to an Int16.   

備註

這個常數的值是-32768;也就是十六進位0x8000。The value of this constant is -32768; that is, hexadecimal 0x8000.

MinValue 屬性通常是用來防止在從具有較低範圍(例如 Int32Int64)的數數值型別轉換成 Int16時,OverflowExceptionThe MinValue property is typically used to prevent an OverflowException when converting from a numeric type with a greater lower range (such as an Int32 or an Int64) to an Int16. 此範例說明這種用法。The example illustrates this usage.
