Server Error in '/ebook1' Application.
Access to the path 'G:\ebook1\picture' is denied.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.UnauthorizedAccessException: Access to the path 'G:\ebook1\picture' is denied.

ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}\ASPNET on IIS 5 or Network Service on IIS 6 and IIS 7, and the configured application pool identity on IIS 7.5) that is used if the application is not impersonating. If the application is impersonating via <identity impersonate="true">, the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user.

To grant ASP.NET access to a file, right-click the file in File Explorer, choose "Properties" and select the Security tab. Click "Add" to add the appropriate user or group. Highlight the ASP.NET account, and check the boxes for the desired access.

The error message is perfectly clear and tells you what/how to do to correct the issue. So, what is your question?

What's the question? It's a permissions issue, as the error states.

This is amazing! You show exception information in detail but no code sample. Others should only the code fragment, without exception information of compilation errors. Does anyone here understand that's it's important to provide both?!

Well, Im going to put my head out there and say that it is some permissions issue no???? :)

Come on, without any code this is really not a question at all..

However, look at this:

Basically, your asp.net website app pool should run under a dedicated account or at least the defaultapppool user. Grant permissions on that folder and you should be away!
