Compiler Error CS0590
User-defined operators cannot return void
The purpose of a user-defined operator is to return an object.
The following sample generates CS0590:
// CS0590.cs
namespace x
{
public class a
{
public static void operator+(a A1, a A2) // CS0590
{
}
// try the following user-defined operator
/*
public static a operator+(a A1, a A2)
{
return A2;
}
*/
public static int Main()
{
return 1;
}
}
}
