Decimal.Increment(Decimal) 操作员

定义

Decimal 操作数增加 1。Increments the Decimal operand by 1.

public:
 static System::Decimal operator ++(System::Decimal d);
public static decimal operator ++ (decimal d);
static member op_Increment : decimal -> decimal
Public Shared op_Increment (d As Decimal) As Decimal

参数

d
Decimal

要递增的值。The value to increment.

返回

d 增加 1 后的值。The value of d incremented by 1.

异常

返回值小于 MinValue 或大于 MaxValueThe return value is less than MinValue or greater than MaxValue.

注解

Increment 方法定义 Decimal 值的增量运算符的运算。The Increment method defines the operation of the increment operator for Decimal values. 它可以实现如下所示的代码:It enables code such as the following:

using System;

public class Example
{
   public static void Main()
   {
      Decimal number = 1079.8m;
      Console.WriteLine("Original value:    {0:N}", number);
      Console.WriteLine("Incremented value: {0:N}", ++number); 
   }
}
// The example displays the following output:
//       Original value:    1,079.80
//       Incremented value: 1,080.80

缺少增量运算符的某些语言(如 Visual Basic)可以直接调用 Increment 方法,如下面的示例所示。Some languages (such as Visual Basic) that lack an increment operator can call the Increment method directly, as the following example shows.

Module Example
   Public Sub Main()
      Dim number As Decimal = 1079.8d
      Console.WriteLine("Original value:    {0:N}", number)
      Console.WriteLine("Incremented value: {0:N}", Decimal.op_Increment(number))
   End Sub
End Module
' The example displays the following output:
'       Original value:    1,079.80
'       Incremented value: 1,080.80

如果你的语言不支持自定义运算符,请改为调用 Add 方法,如下面的示例所示。If your language does not support custom operators, call the Add method instead, as the following example shows.

using System;

public class Example
{
   public static void Main()
   {
      Decimal number = 1079.8m;
      Console.WriteLine("Original value:    {0:N}", number);
      Console.WriteLine("Incremented value: {0:N}", Decimal.Add(number, 1)); 
   }
}
// The example displays the following output:
//       Original value:    1,079.80
//       Incremented value: 1,080.80
Module Example
   Public Sub Main()
      Dim number As Decimal = 1079.8d
      Console.WriteLine("Original value:    {0:N}", number)
      Console.WriteLine("Incremented value: {0:N}", Decimal.Add(number, 1))
   End Sub
End Module
' The example displays the following output:
'       Original value:    1,079.80
'       Incremented value: 1,080.80
