Question

I am getting error in my C# program then I try to write a file with

new StreamWriter("myFile.dat");

This program gets executed by other one and sometimes previous instance of the program blocks the file (don’t know how and why).

Can I write the file anyway with any kind of unblocikng in my code?

Answer 1

You can try opening a FileStream with FileShare.ReadWrite flag. E.g:

new FileStream("myFile.dat", FileMode.OpenOrCreate, FileAccess.Write, FileShare.ReadWrite);

The gives more than one process the ability to write to the file.
