Sorted list : Ambiguous symbol, please help

[SAM2012]

Hi,

I have used this

#using <System.dll>
using namespace System;
using namespace System::Collections::Generic;
using namespace System::Linq;

SortedList<double, String^>^ slist = gcnew SortedList<double, String^>();

in one program its working well. But Now when I pasted the same code with all given headers in second program its not being identified there. Errors are coming.

'SortedList' : ambiguous symbol
1>could be 'c:\program files\reference assemblies\microsoft\framework\.netframework\v4.0\system.dll : System::Collections::Generic:: SortedList'
1>'c:\program files\reference assemblies\microsoft\framework\.netframework\v4.0\mscorlib.dll : System::Collections:: SortedList'

Any help why this error could be avoided. Thanks in advance for sparing time for me.

This is the complete program with two reference classes "message" and "exchange" whose code I haven't pasted here. PLEASE HELP

What is this code supposed to do?
There are a lot of things that can be corrected, but I need to know what is the most important thing or what is the charter of the program.

It looks like if you stick to either CLI or STL, you can get this done.

[SAM2012]

Can you please explain. Why Sorted list only creating problems...

[thines01]

What I'm saying is that is not the only problem with this code.

If you fully-qualify the SortedList, does it help?

System::Collections::Generic::SortedList<double, String^>^ slist = gcnew System::Collections::Generic::SortedList<double, String^>();

[SAM2012]

Thanks , your help to design the code well would be highly appreciated.

[SAM2012]

this program is about sending messaging to queues on basis of different condition. I wanted to correct problems you finding in it. PLEASE HELP

[thines01]

Is your first problem fixed?

[SAM2012]

yes thanks
