+= Operator Overloading

[PBanta]

Is it possible to overload the "+=", "-=", "*=", and "/=" operators in a managed class? If so, how (what is the CLS function name)?

[Zaccheus]

I don't think it is, because operators are declared as static methods in .net assemblies.

Having said that, the following compiles just fine using /clr:safe


ref class X
{
public:
X^ operator*=(X^ a) {return this;}
};
