delegate calling convention

[apm]

Is there a way to change the calling convention of a delegate to Cdecl? Is
it possible to define a callback function in C# that used the Cdecl
convention?

Thanks in advance.

apm,

You can only do this in .NET 2.0. You can apply the
UnmanagedFunctionPointer attribute to the delegate.

In .NET 1.1 and before, you would have to pass your delegate to an
unmanaged piece of code which has the signature of the delegate, and pass
that to your function.

Hope this helps.

Thank you. This is what I have done in the past using C++. Can it be done
with C#?

No, not in v1.x. All you can do is change your C++ code's calling convention
to _stdcall (WINAPI), which is the default for callbacks in Win32. Another
option is to change and reassemble the IL in a post-build step.

I don't have the source.

Interesting.
