How can i implicitly convert my class to another type?

问题:

For example implicitly

回答1:

You need to define this in the MyClass file.

public static implicit operator int(MyClass instance)  {     if (instance == null)      {         return -1;     }     return instance._underlyingValue; } 

回答2:

class MyClass  {    public static implicit operator int(MyClass myClass)     {       // code to convert from MyClass to int    } } 

Take a look there : implicit

This MSDN entry covers what you want exactly, should do the trick.
