[Mono-devel-list] BUG: Static ToString method problem...

[Vadim B. Guzev]

Hello,


I've found a bug in Mono 1.0.
Look at the following files a.cs and q.cs:
8<------------------------------------------------
[vadim at skif static_tostring]$ cat a.cs
using System;
using Q;

public class B {
 public static void Main( string[] args ) {
  Console.WriteLine( A.ToString() );
 }
}
[vadim at skif static_tostring]$ cat q.cs
namespace Q {
 public class A {
  public static new string ToString() {
   return "Hello world!";
  }
 }
}
8<------------------------------------------------

Try to compile them - you'll see the following:

8<------------------------------------------------
[vadim at skif static_tostring]$ mcs /t:library q.cs
Compilation succeeded
[vadim at skif static_tostring]$ mcs /r:q.dll a.cs
a.cs(6) error CS0121: Ambiguous call when selecting function due to implicit casts
a.cs(6) error CS8006: Could not find any applicable function for this argument list
Compilation failed: 2 error(s), 0 warnings
8<------------------------------------------------

The same example works perfectly on MS .Net 1.0. I think that it's a
problem with C# compiler as it was in bug http://bugzilla.ximian.com/show_bug.cgi?id=52931

Here's my system info:
