System.IO.IOException: 'The process cannot access the file '@.txt' because it is being used by another process.'

Question

I am new to programming and I have a question. If I have two functions, one creates a text file and writes into it, while the other opens the same text file and reads from i

Answer 1

The issue is sometimes file locks don't get released immediately after they are closed.

You can try run a loop to read the file. Inside the loop put a try catch statement and if the file reads successfully break from the loop. Otherwise, wait a few milliseconds and try to read the file again:

string originalText = null;
while (true)
{
    try
    {
        originalText = File.ReadAllText(@"C:\Users\...\fileName.txt", Encoding.Default);
        break;
    }
    catch 
    { 
        System.Threading.Thread.Sleep(100);
    }
}
