Compiler Error CS0562
The parameter of a unary operator must be the containing type
The method declaration for an operator overload must follow certain guidelines. For more information, see Overloadable Operators and Operator Overloading Sample.
The following sample generates CS0562:
// CS0562.cs
public class iii
{
public static implicit operator int(iii x)
{
return 0;
}
public static implicit operator iii(int x)
{
return null;
}
public static iii operator +(int aa) // CS0562
// try the following line instead
// public static iii operator +(iii aa)
{
return (iii)0;
}
public static void Main()
{
}
}
