F＃运算符重载

操作员重载是一种方法, 通过该方法可以根据你的自定义需要重新定义操作员行为。你可以重载所有算术运算符。运算符必须定义为静态。所有一元运算符都必须使用〜（平铺）运算符表示这是一元运算符。

F＃运算符重载示例

type OperatorOverloading(x: int, y : int) =
   member this.X = x
   member this.Y = y
   static member (+) (v : OperatorOverloading, a) =
     OperatorOverloading(a + v.X, a + v.Y)
  
   override this.ToString() =
     this.X.ToString() + " " + this.Y.ToString()

let operatorOverloading = OperatorOverloading(5, 3)

let operatorOverloading2 = operatorOverloading + 10


printfn "%s" (operatorOverloading.ToString())
printfn "%s" (operatorOverloading2.ToString())

输出：

5 3
15 13
