## 定義

``````public:
static System::Decimal operator +(System::Decimal d1, System::Decimal d2);``````
``public static decimal operator + (decimal d1, decimal d2);``
``static member ( + ) : decimal * decimal -> decimal``
``Public Shared Operator + (d1 As Decimal, d2 As Decimal) As Decimal``

d1
Decimal

d2
Decimal

#### 傳回

`d1``d2` 相加的結果。The result of adding `d1` and `d2`.

## 備註

Addition 方法會定義 Decimal 值之加號的運算。The Addition method defines the operation of the addition operator for Decimal values. 它會啟用如下所示的程式碼：It enables code such as the following:

``````using System;

public class Example
{
public static void Main()
{
Decimal number1 = 120.07m;
Decimal number2 = 163.19m;
Decimal number3 = number1 + number2;
Console.WriteLine("{0} + {1} = {2}",
number1, number2, number3);
}
}
// The example displays the following output:
//        120.07 + 163.19 = 283.26
``````
``````Module Example
Public Sub Main()
Dim number1 As Decimal = 120.07d
Dim number2 As Decimal = 163.19d
Dim number3 As Decimal = number1 + number2
Console.WriteLine("{0} + {1} = {2}",
number1, number2, number3)
End Sub
End Module
' The example displays the following output:
'       120.07 + 163.19 = 283.26
