Question

I have a dynamic library (.dll) written in C++ exporting a function I’d like to use in my C# applicaiton:

int SendText(void* pControl, char* sText);

How can I, given it takes a pointer to void?

Answer 1

for void* you can just use IntPtr ,
strings will work with the MarshalAs attribute:

[DllImport("MyDll.dll", CharSet = CharSet.Ansi)]
public static extern int SendText(IntPtr pControl, [MarshalAs(UnmanagedType.LPStr)] string sText);
