Question

typecast operator is cool in c++, no such thing in c#?

c++ code:

class A
{
int dat;

public:
A(int num = 0 ) : dat(num) {}

operator int() {return dat;} // cast to int
};

Answer 1

C# has! here couple examples from MSDN:
Explicit:

public static explicit operator Celsius(Farenheit f)
{
    return new Celsius((5.0f/9.0f)*(f.degrees-32));
}

Implicit:

//  User-defined conversion from double to Digit
public static implicit operator Digit(double d)
{
    return new Digit(d);
}
