public void CreateTextFile(string fileName, string textToAdd) {
         string logFile = DateTime.Now.ToShortDateString()
            .Replace(@"/",@"-").Replace(@"\",@"-") + ".log";
         
         FileStream fs = new FileStream(fileName,
            FileMode.CreateNew, FileAccess.Write, FileShare.None);
         
         StreamWriter swFromFile = new StreamWriter(logFile);
         swFromFile.Write(textToAdd);
         swFromFile.Flush();
         swFromFile.Close();         StreamWriter swFromFileStream = new StreamWriter(fs);
         swFromFileStream.Write(textToAdd);
         swFromFileStream.Flush();
         swFromFileStream.Close();         StreamWriter swFromFileStreamDefaultEnc = 
            new System.IO.StreamWriter(fs, 
            System.Text.Encoding.Default);
         swFromFileStreamDefaultEnc.Write(textToAdd);
         swFromFileStreamDefaultEnc.Flush();
         swFromFileStreamDefaultEnc.Close();         StreamWriter swFromFileTrue = 
            new StreamWriter(fileName,true);
         swFromFileTrue.Write(textToAdd);
         swFromFileTrue.Flush();
         swFromFileTrue.Close();
         
         StreamWriter swFromFileTrueUTF8Buffer = 
            new StreamWriter(fileName, 
            true, System.Text.Encoding.UTF8,512);
         swFromFileTrueUTF8Buffer.Write(textToAdd);
         swFromFileTrueUTF8Buffer.Flush();
         swFromFileTrueUTF8Buffer.Close();         StreamWriter swFromFileTrueUTF8 = 
            new StreamWriter(fileName, true,
            System.Text.Encoding.UTF8);
         swFromFileTrueUTF8.Write(textToAdd);
         swFromFileTrueUTF8.Flush();
         swFromFileTrueUTF8.Close();         StreamWriter swFromFileStreamUTF8Buffer = 
            new StreamWriter(fs, System.Text.Encoding.UTF8, 512);
         swFromFileStreamUTF8Buffer.Write(textToAdd);
         swFromFileStreamUTF8Buffer.Flush();
         swFromFileStreamUTF8Buffer.Close();
