Question

I’m uring StreamReader to read/write from/to a file in two threads, read in one and write in other. I want that these two don’t occur at the same time. What lock should I use? I looked at some examples but they were using FileStream.Lock and I’m not sure whether I can use that with StreamReader so please clarify.

Answer 1

You could create your own lock:

class Example
{
    private static readonly object SyncRoot = new object();

    void ReadOrWrite()
    {
        lock(SyncRoot)
        {
            // Perform a read or write
        }
    }
}
