Error while importing fortran DLL in C#.NET

Error while importing fortran DLL in C#.NET

(OP)
thread214-1572697: How to make DLL's in fortran

Hello Developers!!

I have to import a fortran dll in C#.net I use the following code, but receive an error- "Unable to find an entry point named '0x0000100F' in DLL <DLL_Name>"

Code Snippet: (C#.net)
namespace Application
{
public class FortranDllWrap
{
[DllImport(@"C:\Users\XYZ\Documents\Visual Studio 2008\Projects\TestConsoleApplication\TestConsoleApplication\Debug\TestDLL.dll", CallingConvention = CallingConvention.Cdecl, EntryPoint = "0x0000100F")]
public static extern void mainsubroutine();
}

private void btnSubmit_Click(object sender, EventArgs e)
{
FortranDllWrap.mainsubroutine();
}
}

I found the EntryPoint of this DLL using the tool- "Dependency Walker"
I want to attach a screenshot of this tool but I think there is no way I can attach a copy.
Any information would be greatly appreciated. I really don't understand where am I going wrong. Please Help!

Looking forward for your response. Thanks in advance!

RE: Error while importing fortran DLL in C#.NET

Calling convention for Fortran is stdcall: not cdecl.

Do you need to specify the entrypoint?
