I want to delete a file on run time but the error showing is "cannot access a file because it is used by another process" or "cant delete a read only file".A '.dll' file is attached to the code. If '.dll' file is not attached it works fine.
Is there any way to solve the above error.

C#

if ((Directory.Exists(@"C:\\Users\\Anand\\Desktop\\temp_image)))
           {
               Directory.Delete(@"C:\\Users\\Anand\\Desktop\\temp_image, true);
           }

Here temp_image is the folder, I want to delete.

What is that DLL, where it is used? Does your application create this folder?

Because it's named "temp_image" it's likely that it contains pictures your application is using - and that's probably the problem.
If you use Image.FromFile or similar, then it acquires a lock on the file until the Image is Disposed (it's all in teh documentation: Image.FromFile Method (String) (System.Drawing)[^] - see the Remarks section)

So look at the rest of your code, and how you are handling the images and files - until you have corrected that, you can't delete the folder as your application is using files inside it.

Firstly use 'Process Explorer'[^] to see which process is using the file. If the process turns out to be your project's executable file try to do the following checks

1. Make sure you properly close and (or) dispose all System.IO.StreamReader(s) and System.IO.StreamWriter(s)
2. Make sure there's no code in your class library(.dll) accessing the file at runtime
