Question

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;

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.

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

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

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

And you would use it like so:

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

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