Why Does Saving an Image in .NET C# Result in a 'Path Access Denied' Error?

Troubleshooting .NET C# Image Saving Errors: "Access Denied"

Saving images in .NET C# can sometimes throw an "Access to the path is denied" exception. Even after granting full access permissions to network services (like IIS_IUSRS), and even "Everyone," the problem may remain.

Root Cause and Solution

The error often points to a path like "C:inetpubwwwrootmysiteimagessavehere". The core issue is attempting to save an image with the same name as an existing directory.

The file system prevents overwriting a directory with a file to avoid potential data loss. The "Access Denied" message, though not perfectly clear, is the OS's safeguard against this.

The solution is simple: use a unique file name within the target directory. For example, "C:inetpubwwwrootmysiteimagessaveheremyimage.jpg" is a valid path. Employing the Path.Combine method ensures reliable path construction.
