I have a dll which accepts a struct that contains a pointer to a function to do a callback.
How can I get an IntPtr to a function of my application to build the struct?
[StructLayout(LayoutKind.Sequential, CharSet = CharSet.Ansi)]
public class OPERATION {
public uint OperationID;
public IntPtr Context;
public IntPtr Callback; -> How to pass this?
}
Here is the delegate accepting the OPERATION struct
public delegate void MY_CALLBACK([In] OPERATION operation, [In] uint msgId, [In] IntPtr msgDataPtr);
也许Marshal.GetFunctionPointerForDelegate方法可以帮助你。
