when link to C# dll from EA, there has been a critical error

New comment
 

I have some method at C# dll, so i think to call C# dll from MT4 EA, but don't know how to do it.
now i do it other in another way.
1.I created C++ dll,then from this dll to call C# dll,i think it is ok,because i can get the result from a test application used the same code.
2.I call this C++dll from mt4 EA, when i commented the code calling C# dll, it works fine.
3.now i am from MT4 EA to call C# dll through C++ dll,
there has been a criticall error...
