Compiler Error CS0410

No overload for 'method' has the correct parameter and return types

This error occurs if you try to instantiate a delegate with a function that has the wrong parameter types. The parameter types of the delegate must match the function that you are assigning to the delegate.

Example

The following example generates CS0410:

// CS0410.cs
// compile with: /langversion:ISO-1

class Test
{
    delegate void D(double d );
    static void F(int i) { }

    static void Main()
    {
        D d = new D(F);  // CS0410
    }
}

Note

This compiler error is no longer used in Roslyn. The previous example generates CS0123 when compiled with Roslyn.
