在C#中是否有像我们在C++中那样的违约功能参数?

指称:

foo(int i = 10, int j  = 20) {}
最佳回答

Named和任择参数在C# 4.0中是新的。

问题回答

是的,缺省参数载于C# 4.0。

你们只能在C# 4.0中这样做。

如果你没有C# 4,你可以确定你的两种方法:

    public int MySillyMethod(int a)
    {
        return MySillyMethod(a, 1);
    }

    public int MySillyMethod(int a, int b)
    {
        return a*b;
    }
