Hello,
First of all, I know that it is not the right place to send bug =
reports, but
I can't access Bugzilla at work...
I have a problem when executing this code with mono 0.24:
using System.Collections;
class Problem
{
public static void Main(string[] args)
{
SortedList list =3D new SortedList();
list.Add(list.Count, new Queue());
list.Add(list.Count, new Hashtable());
list.Add(list.Count, new Stack());
foreach (DictionaryEntry de in list)
{
System.Console.WriteLine("Item #{0} =3D {1}", de.Key,
de.Value.GetType().FullName);
}
}
}
This code compiles fine with mcs 0.24 and csc 1.0
When executed with ms runtime (1.0), results are ok:
Item #0 =3D System.Collections.Queue
Item #1 =3D System.Collections.Hashtable
Item #2 =3D System.Collections.Stack
When executed with mono, a runtime error occurs (at the foreach line):
Unhandled Exception: System.InvalidCastException: Cannot cast from =
source
type to destination type
in <0x00207> 00 .Problem:Main (string[])
What am I doing wrong?
Thanks a lot for your porting of .Net technology to *nix systems
