Description of unmanaged exposed dll functions

[jayderk]

I can not seem to find the thread that described how to expose the functions
of functions that are usable in an unmanaged dll? any help would be great

I use dumpbin.exe -exports "C:\Computer\Pr ograms\MyUnmana ged.dll"

If it is a C++ DLL, you may have to access the functions by ordinal. If it
is C, you should be able to access them by name.
You'll have to use P/Invoke (Platform Invoke) to call the functions. Once
you declare the function as shown below,
you can call it as you would any other C# method. If the unmanaged functions
have tricky parameters, you'll have to
study up a bit on P/Invoke to figure out which .NET types to substitute for
the unmanaged parameter types.

//example for C++ name mangling -- use ordinal as shown with # prefix
[DllImport("MyUn managed.dll", EntryPoint="#46 ")]
private static extern void MyExportedMetho dOrdinal46(int k);

//example for unmangled names (C style)
[DllImport("MyUn managed.dll", EntryPoint="Set SpecialTreatmen t")]
private static extern void SetSpecialTreat ment(int action);
