have an application that accesses a directory and via the SoundPlayer class I access a file. Wav. I have the following C #:
public void PlaySound()
{
try
{
while (true)
{
List<string> distinctMusicFile = GetMusicFile.Distinct().ToList();
if (DataTableWorkCall.GetDataTableNew.Rows.Count > 0)
{
for (int i = 0; i < distinctMusicFile.Count; i++)
{
StopSound();
player.SoundLocation = distinctMusicFile[i];
player.Play();
Thread.Sleep(Convert.ToInt32(ConfigurationSettings.AppSettings["MusicDuration"]) * 1000);
StopSound();
}
}
else
GetMusicFile.Clear();
}
}
catch (ThreadAbortException e)
{
if (generateLog)
log.LogTxt("Finished...\n");
}
catch (UnauthorizedAccessException e)
{
if (generateLog)
log.LogTxt(e.ToString());
}
}
This code is generating this exception:
Application: AndonGestamp_FormMonitoramento.exe
Framework Version: v4.0.30319
Description: The process was terminated due to an unhandled exception.
Exception Info: System.UnauthorizedAccessException

Log generation:
public void LogTxt(string msg)
{
string logDirectory = ConfigurationSettings.AppSettings["Log"].ToString();
if (!System.IO.File.Exists(logDirectory))
{
System.IO.File.Create(logDirectory).Close();
}
if (msg != null)
{
System.IO.TextWriter file = System.IO.File.AppendText(logDirectory);
file.WriteLine(msg + " " + DateTime.Now + "\n");
file.Close();
}
}
The function log.LogTxt (String) creates a txt file, can this be? Problems regarding permissions? Can anyone help me? Thanks!
The line
at AndonGestamp_FormMonitoramento.Utils.Log.LogTxt(System.String)
shows that the exception stems from LogTxt.
Your conclusion that it is a permission problem is correct.
If you cannot find the problem through visual inspection of your code; trace to as close as you can to the row that fails and start ProcessMonitor to find where/what your code tries to reach.
