Byte.MaxValue 字段

定义

表示 Byte 的最大可能值。Represents the largest possible value of a Byte. 此字段是常量。This field is constant.

public: System::Byte MaxValue = 255;
public const byte MaxValue = 255;
val mutable MaxValue : byte
Public Const MaxValue As Byte  = 255

字段值

示例

下面的示例演示如何使用 MaxValue 字段来对超出可能字节值范围的值的变量输入进行屏蔽。The following example demonstrates how to use the MaxValue field to screen variable inputs for values that are outside the range of possible byte values.

public:
   void MinMaxFields( Int32 numberToSet )
   {
      if ( numberToSet <= (Int32)Byte::MaxValue && numberToSet >= (Int32)Byte::MinValue )
      {
         
         // You must explicitly convert an integer to a byte.
         MemberByte = (Byte)numberToSet;
         
         // Displays MemberByte using the ToString() method.
         Console::WriteLine(  "The MemberByte value is {0}", MemberByte.ToString() );
      }
      else
      {
         Console::WriteLine(  "The value {0} is outside of the range of possible Byte values", numberToSet.ToString() );
      }
   }
public void MinMaxFields(int numberToSet)
{
   if(numberToSet <= (int)Byte.MaxValue && numberToSet >= (int)Byte.MinValue)
   {
      // You must explicitly convert an integer to a byte.
      MemberByte = (Byte)numberToSet;

      // Displays MemberByte using the ToString() method.
      Console.WriteLine("The MemberByte value is {0}", MemberByte.ToString());
   }
   else
   {
      Console.WriteLine("The value {0} is outside of the range of possible Byte values", numberToSet.ToString());
   }
}
Public Sub MinMaxFields(ByVal numberToSet As Integer)
   If numberToSet <= CInt([Byte].MaxValue) And numberToSet >= CInt([Byte].MinValue) Then
      ' You must explicitly convert an integer to a byte.
      MemberByte = CType(numberToSet, [Byte])

      ' Displays MemberByte using the ToString() method.
      Console.WriteLine("The MemberByte value is {0}.", MemberByte.ToString())
   Else
      Console.WriteLine("The value {0} is outside of the range of possible Byte values.", numberToSet.ToString())
   End If
End Sub

注解

此常量的值为255(十六进制0xFF)。The value of this constant is 255 (hexadecimal 0xFF).
