Byte.MaxValue 字段

定义

表示 Byte 的最大可能值。 此字段为常数。

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

字段值

Value = 255
Byte

示例

下面的示例演示如何使用 字段筛选超出可能字节值范围 MaxValue 的值的变量输入。

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());
   }
}
let minMaxFields numberToSet =
    if numberToSet <= int Byte.MaxValue && numberToSet >= int Byte.MinValue then
        // You must explicitly convert an integer to a byte.
        let myByte = byte numberToSet

        printfn $"The MemberByte value is {myByte}"
    else
        printfn $"The value {numberToSet} is outside of the range of possible Byte values"
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) 。
