字符串化成员名称，类似于C中的#define str(s)#s [英] Stringify member name similar to #define str(s) #s in C

问题描述

是否可以像在C中使用#define str(s) #s宏那样在.NET 4.0的C#中对成员名称进行字符串化?

Is there any way to stringify a member name in C# for .NET 4.0 like you would in C by using the #define str(s) #s macro?

public Double MyDouble
{
    get { return _MyDouble;}
    set 
    { 
        _MyDouble = value; 
        RaisePropertyChanged("MyDouble");
        // The below item would refactor correctly if C# had a stringify pre-processor
        // RaisePropertyChanged(str(MyDouble));
    }
}
private Double _MyDouble;

如果禁用了Search in Strings，则重新分解会中断raise属性更改事件，如果启用，则会破坏完全不相关的字符串.有时，直到UI元素不再响应更改时，我才注意到.

Re-factorization breaks the raise property changed event if I have Search in Strings disabled or breaks completely unrelated strings if it is enabled. Sometimes I won't notice until a UI element no longer responds to changes.

推荐答案

不幸的是，没有.当前，您必须使用PostSharp或 NotifyPropertyWeaver 之类的东西来可靠地做到这一点.

No, unfortunately. Currently you would have to use something like PostSharp or NotifyPropertyWeaver to do this reliably.

请注意，在C#5中，您可以执行以下操作:

Note that in C# 5 you'll be able to do this:

public void RaisePropertyChanged([CallerMemberName] string member = "")
{
}

您将像这样使用它:

public Double MyDouble
{
    get { return _MyDouble;}
    set 
    { 
        _MyDouble = value; 
        RaisePropertyChanged();
    }
}

C#5编译器将自动填写可选参数.

And the C# 5 compiler will automatically fill in the the optional parameter.
