Here is my code:

public static TextWriter twLog = null;
private int fileNo = 1;
private string line = null;

TextReader tr = new StreamReader("file_no.txt");
TextWriter tw = new StreamWriter("file_no.txt");
line = tr.ReadLine();
if(line != null){
    fileNo = int.Parse(line);
    twLog = new StreamWriter("log_" + line + ".txt");
}else{
    twLog = new StreamWriter("log_" + fileNo.toString() + ".txt");  
}
System.IO.File.WriteAllText("file_no.txt",string.Empty);
tw.WriteLine((fileNo++).ToString());
tr.Close();
tw.Close();
twLog.Close();

It throws this error:

IOException: Sharing violation on path C:\Users\Water Simulation\file_no.txt

What i'm trying to do is just open a file with log_x.txt name and take the "x" from file_no.txt file.If file_no.txt file is empty make log file's name log_1.txt and write "fileNo + 1" to file_no.txt.After a new program starts the new log file name must be log_2.txt.But i'm getting this error and i couldn't understand what am i doing wrong.Thanks for help.

         var stream = new System.IO.FileStream(filePath, System.IO.FileMode.Create);

        resizedBitmap.Compress(Bitmap.CompressFormat.Png, 200, stream); //problem here
        stream.Close();
        return resizedBitmap;

In the Compress method, I was passing the value of the quality parameter as 200, which sadly doesn't allows values outside the range 0-100.

I changed back the value of quality to 100 and the issue got fixed.

None of the proposed options helped me. But I found a solution: In my case, the problem was with Anti-Virus, with intensive writing to a file, Anti-Virus started scanning the file and at that moment there was a problem with writing to the file.
