unable to call a function

Thanks....it works fine now....there was a silly mistake i made over there.

Are you sure that the method in your class is declared to be either public or internal?

If you don't specify an access modifier, methods are private by default and not accessible outside the class in which they're defined.

What exception, if possible share your code.

hi
check the class it is public class or not
public class sample
{

}
