asp.net - ASP .NET WebSite with importing DLL-s -

I have your file. Trying to call a DLL function in Aspx.cs:

  [DllImport ("the.dll")] Private static extern bool function (int width, int height);  

and:

• The file is in "the.dll" "C: \ Windows \ System32 \ inetsvr"
• My Web Site is an application that has the privilege to read and execute
• If I try to file Example ("the.dll") is correct on the server, so DLL

but:

• If I click on the page on the local host I'm trying to run, so all is well.
• If I try to play the uploaded page on the IIS server, then loads on the infinite page ... nothing appears, Nothing happens! And then IIS is blocked and I have to restart the server.

What am I doing wrong? Check the security and permission settings on IIS OI about IIS

In addition to attempting to insert bin folder in the dill Please.
