Make sure the library is in a directory below the website root.

Why don't you just add as a reference. You have permissions issue but just add as reference.

ZurdoDev 10-Jan-14 8:23am

OK. But it looks like you have permissions issues then.

Yes But DllIMPORT Working On Local And IIS server but when i upload on web server they throws the error

ZurdoDev 10-Jan-14 8:29am

Which is the typical symptom of a permissions issue. The account running the site on the web server does not have the proper permissions to the file.

any solution for this

ZurdoDev 10-Jan-14 8:31am

Sure. Give the account that is running the app pool in IIS the proper permissions.

Means Change the Settings of IIS in Web Server

ZurdoDev 10-Jan-14 8:37am

No. Go into IIS and find out which app pool your website is using. Then find out what the identity of that app pool is. That is the account that needs permissions to load the file.

pradip2609 10-Jan-14 8:44am

Application Pool is DefaultAppPool

ZurdoDev 10-Jan-14 8:46am

Now find the identity of that app pool.

in Web Server
