file in use message when trying to write out Request

I am using the code from this post IIS 7 Log Request Body so that I can see what is happening when people attempt to access my site. 

protected void Application_BeginRequest(Object sender, EventArgs e)
{
  var uniqueid = DateTime.Now.Ticks.ToString(CultureInfo.InvariantCulture);
  var logfile = String.Format("C:\\logs\\{0}.txt", uniqueid);
  Request.SaveAs(logfile, true);
}

When it runs though, I am getting this message:

The process cannot access the file 'C:\logs\635256490792288683.txt' because it is being used by another process.

Every once in a while, people are having the of no response from the site and I desperately need to find out what is happening.

Any idea how to resolve this?

Solution

  • The resolution of DateTime.Now is not good enough for what you are trying to do. For a quick fix, you could use new Guid().ToString(); but dont do this in production, it is going to really hurt your site performance.
