Here's a quick and dirty log routine I use in apps on occasion:

        /// <summary>
        /// Simple Logging method that allows quickly writing a string to a file
        /// </summary>
        /// <param name="output"></param>
        /// <param name="filename"></param>
        public static void LogString(string output, string filename)
        {
            StreamWriter Writer = new StreamWriter(filename, true);
            Writer.WriteLine(DateTime.Now.ToString() + " - " + output);
            Writer.Close();
        }

This version appends to the end of the file.

Note if you do this in ASP.NET you have to give the Web application rights to write in the output path - by default it won't have those rights.
