How can I write to a file that is in use by another process in C#?

Question

How can I write to a file which is used by another process in C#?

I am able to read the file using FileShare.ReadWrite, but it only works for FileAccess.Read. Does anyone have a solution?

A voice in my head tells me that you should not be doing this. Some description of your scenario will help. — Unmesh Kondolikar

I don't suppose that this is a file you created yourself, using something like File.Create? — Cody Gray

If the other process has write-locked the file, then there's not much you can do, unless you don't mind closing the other process's handle or killing it.

Yes, this is correct. And even if you don't mind, that other process most certainly does. So don't do this.

You should read the file contents to a separate Stream and then the file is released.
