copied!<p>This might be what you're looking for (I've answered similiar question here before: <a href="https://stackoverflow.com/questions/18126017/how-to-use-c-projects-for-windows-phone-c/18128735#18128735">how to : use c++ projects for windows phone (C#)</a>)</p> <p>a) Load symbols directly from C library, for example:</p> <pre><code>using System; using System.Runtime.InteropServices; static class win32 { [DllImport("kernel32.dll")] public static extern IntPtr LoadLibrary(string dllToLoad); [DllImport("kernel32.dll")] public static extern IntPtr GetProcAddress(IntPtr hModule, string procedureName); [DllImport("kernel32.dll")] public static extern bool FreeLibrary(IntPtr hModule); } </code></pre> <p>(this is taken from: <a href="http://www.andyrushton.co.uk/csharp-dynamic-loading-of-a-c-dll-at-run-time/" rel="nofollow noreferrer">http://www.andyrushton.co.uk/csharp-dynamic-loading-of-a-c-dll-at-run-time/</a> after brief googling)</p> <p>You need to export the C++ interface methods as "C" for that, e.g.:</p> <pre><code>extern "C" __declspec( dllexport ) int MyFunc(long parm1); </code></pre> <p>(from MSDN: <a href="http://msdn.microsoft.com/en-us/library/wf2w9f6x.aspx" rel="nofollow noreferrer">http://msdn.microsoft.com/en-us/library/wf2w9f6x.aspx</a>)</p> <p>b) Use a wrapper in C++/CLI to connect unmanaged C++ to managed C#:</p> <p>here's a good example: <a href="http://www.codeproject.com/Articles/19354/Quick-C-CLI-Learn-C-CLI-in-less-than-10-minutes" rel="nofollow noreferrer">http://www.codeproject.com/Articles/19354/Quick-C-CLI-Learn-C-CLI-in-less-than-10-minutes</a></p> <p>Do note that the syntax is somewhat weird at first look, and not eveything can be used. However, what you gain is ability to use the C++ classes - something that exporting "C" prohibits you from doing.</p>
