Did you check if the file that your accessing is being opened already..?

Its mean the image still not uploaded to the server.
its in process of uploading.
after uploading 100% then you can access that file

Solution 1

should added the FileAccess and FileShare tag.

C#

fs = new FileStream (zipFilepath, FileMode.Create, FileAccess.ReadWrite, FileShare.ReadWrite)

Yes, it will work, but this is not a right advice, in most cases. Usually, the file should not be shared, but it should be closed properly after use.

How do you make sure file is not used by another process? Very interest it.

As this file is an image file, first take a look at the recent discussion: how delete file after use Image.FromFile() in c#[^].

From my experience, the most usual case of blocking a file is blocking it by the same process. When some file is opened, it can be opened for exclusive singe use, or for shared use. By default, and in most cases, files are opened exclusively. In your code, you don't show where and how you close the file handles, and it can be a problem.

Fortunately, this situation is easy enough to investigate. Please see my past answers:
File used by another process exception[^],
how to compress the error 'it is already used by another process' in vb.net[^].
