Decimal.Increment(Decimal) 運算子

定義

命名空間:

System

組件:

System.Runtime.dll

來源:

Decimal.cs

將 Decimal 運算元加 1。

public:
 static System::Decimal operator ++(System::Decimal d) = System::Numerics::IIncrementOperators<System::Decimal>::op_Increment;

public static decimal operator ++ (decimal d);

static member op_Increment : decimal -> decimal

Public Shared op_Increment (d As Decimal) As Decimal

參數

d

Decimal

要遞增的值。

傳回

Decimal

加 1 的 d 值。

實作

Increment(TSelf)

例外狀況

OverflowException

傳回值小於 Decimal.MinValue 或大於 Decimal.MaxValue。

備註

方法 Increment 會針對值定義遞增運算子的作業 Decimal 。 它會啟用下列程式碼：

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

open System

let number = 1079.8m
printfn $"Original value:    {number:N}"
printfn $"Incremented value: {Decimal.op_Increment number:N}"

// The example displays the following output:
//       Original value:    1,079.80
//       Incremented value: 1,080.80

某些語言 (，例如缺少遞增運算子的 Visual Basic) 可以直接呼叫 Increment 方法，如下列範例所示。

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

如果您的語言不支援自訂運算子，請改為呼叫 Add 方法，如下列範例所示。

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

open System

let number = 1079.8m
printfn $"Original value:    {number:N}"
printfn $"Incremented value: {Decimal.Add(number, 1):N}"

// 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
