Summary: GMCS error CS0654 Method is referenced without
parentheses
Product: Mono: Compilers
Version: 2.0.x
Platform: Other
OS/Version: Other
Status: NEW
Severity: Normal
Priority: P5 - None
Component: C#

Basically, the error only occurs if a method has overloads to either accept a
value or a delegate that returns that same value. In that case, when you pass
the a function that returns that value, mono thinks you are trying to call the
one that takes the value and forgot the parentheses.
-------------------------
using System;
namespace MonoTester {
public delegate Value Handler();
class Program {
static void Main(string[] args) {
Do(Value.Default);
Do(Value.Default());
}
public static void Do(Value v) {}
public static void Do(Handler h) {}
}
public class Value {
public static Value Default() {
return new Value();
}
}
}
-------------------------------------
Macintosh-3:mono arne$ gmcs Program.cs
Program.cs(7,22): error CS0654: Method `MonoTester.Value.Default()' is
referenced without parentheses
Compilation failed: 1 error(s), 0 warnings
However this second version works fine... no idea why. Because the Method being
passes is in the same class?
-----------------------------------------
namespace MonoTester {
public delegate Value Handler();
class Program {
static void Main(string[] args) {
Do(Program . Default);
Do(Program . Default());
}
public static void Do(Value v) {}
public static void Do(Handler h) {}
public static Value Default() { return null; }
}
public class Value {
}
}
