Compiler Error CS1618
Cannot create delegate with 'method' because it has a Conditional attribute
You cannot create a delegate with a conditional method because the method might not exist in some builds.
The following sample generates CS1618:
// CS1618.cs
using System;
using System.Diagnostics;
delegate void del();
class MakeAnError {
public static void Main() {
del d = new del(ConditionalMethod); // CS1618
// Invalid because on builds where DEBUG is not set,
// there will be no "ConditionalMethod".
}
// To fix the error, remove the next line:
[Conditional("DEBUG")]
public static void ConditionalMethod()
{
Console.WriteLine("Do something only in debug");
}
}
