PInvoke and MissungMethod exception

[Patrick Theobald]

hi all!!

I'm trying to invoke a function that is located in a C-coded Win32-dll.
I copied the dll into the \windows\ directory of the mobile device.
The declaration is quite simple and looks like this:

[DllImportAttribute("foodll.dll",EntryPoint="foo")]
internal static extern int foo(int h);

When I try to invoke the function

int ret = foo(1);

I get an MissingMethod exception.
I already checked the function names by using dumpbin.exe. They seem to be
ok.

What can do? Any cool tips?

Thank in advance,

Patrick Theobald

Make sure that you compile foodll.dll for correct processor type:
* X86 for emulator
* ARM (maybe other) for your device

How did you declare the function in the DLL?

You're not giving us enough info. Based on your comments it seems you're
fine, but we need to see the C declaration of the function and what
processor you've compiled it for.
