Summary: Casting bug with generic collections
Product: Mono: Class Libraries
Version: 1.2
Platform: PC
OS/Version: Ubuntu
Status: NEW
Severity: Normal
Priority: P5 - None
Component: System
AssignedTo: [EMAIL PROTECTED]
ReportedBy: [EMAIL PROTECTED]
QAContact: [EMAIL PROTECTED]
Found By: Development
The code below compiles and runs fine with VS 2005 and prints "a".
With Mono 1.2.4, I get a cast exception:
Unhandled Exception: System.InvalidCastException: Cannot cast from
source type to destination type.
at System.Collections.Generic.Dictionary
2+KeyColleciton[System.String,System.String].System.Collections.ICollection.CopyTo
(System.Array , Int32 ) [0x00000]
Here is the code:
System.Collections.Generic.Dictionary<string, string> d =
new System.Collections.Generic.Dictionary<string, string>();
d["a"] = "b";
System.Collections.ICollection keys = d.Keys;
object[] keyArray = new object[d.Count];
keys.CopyTo(keyArray, 0);
System.Console.WriteLine(keyArray[0]);
Cheers,
Michi.
