The following code sample shows a typical use of the managed logger to log the start of a test case, a message, an error, and the end of a test case.

using System;
using System.IO;
 
//for logger namespace
using Microsoft.Wtt.Log;
 

namespace testApp
{
    class TestCase
    {
        public TestCase(){}
        public bool InitializeTestCase(string initializationFileName)
        {
            // Perform initialization
            return true;
        }
    }
 
    class MainClass
    {
        [STAThread]
        static void Main(string[] args)
        {
            WttLogger Logger = new WttLogger("$LogFile;$Console");
 
            // Start a test case
            Logger.StartTest("Test 1 - Testing Tracing functions");
 
            Logger.Trace(new LevelError(0x3,ErrorType.Win32,"break"));
 
            // Trace machine info
            Logger.TraceMachineInfo();
 
            // Trace a message by using a message string
            Logger.Trace(new LevelMessage("Testing Tracing Messages"));
 
            // Trace a message by using a user object only
            TestCase userObject = new TestCase();

            Logger.Trace(new LevelMessage(userObject));
 
            // Trace a message by using a user object and a message string
            Logger.Trace(new LevelMessage("Testing Tracing Messages with user Objects",userObject));
 
            // Trace a normal error
            Logger.Trace(new LevelError(0x3,ErrorType.Win32, "Testing Tracing Errors"));
 
            try
            {
                // Generate IOException
                File.Open("c:\toot.txt",FileMode.Open,FileAccess.Read,FileShare.Read);
            }
            catch(Exception exp)
            {
                // Trace an exception error
                Logger.Trace(new LevelError(exp));
            }
 
            // End test case
            Logger.EndTest("Test 1 - Testing Tracing functions", 0, null);
        }    
    }
}
