   In Visual Studio .NET, Class1.cs is created by default. In Visual Studio 2005, Program.cs is created by default.
4. In the code window, replace the code with the following:

   using System;
   using System.Net;
   using System.IO;   
   
   namespace WebDavNET
   {
    /// <summary>
    /// Summary description for Class1.
    /// </summary>
    class Class1
    {
     static void Main(string[] args)
     {
      try 
      {
       // TODO: Replace with the name of the computer that is running Exchange 2000.
       string  strServer = "ExchServe";
       // TODO: Replace with the sender's alias.
       string  strSenderAlias = "sender";  
       // TODO: Replace with the sender's e-mail address.
       string  strFrom = "sender@example.com"; 
       // TODO: Replace with the recipient's e-mail address.
       string  strTo = "recipient@example.com"; 
    
       string  strSubject = "Send Using HttpWebRequest";
       string  strBody = "Hello World";
   
       string sUri;
       sUri = "http://" + strServer + "/Exchange/" + strSenderAlias;
       sUri = sUri + "/%23%23DavMailSubmissionURI%23%23/"; 
   
       System.Uri myUri = new System.Uri(sUri);
       HttpWebRequest HttpWRequest = (HttpWebRequest)WebRequest.Create(myUri);
   
       string sQuery;
       DateTime mySentTime = new DateTime();
       sQuery = "From: " + strFrom + "\n" +

       NetworkCredential myCred = new NetworkCredential(@"DomainName\User", "Password");
       CredentialCache myCredentialCache = new CredentialCache();
       myCredentialCache.Add(myUri, "Basic", myCred);
       HttpWRequest.Credentials = myCredentialCache;
   
       // Set the headers.
       HttpWRequest.Headers.Set("Translate", "f");
       HttpWRequest.ContentType =  "message/rfc822";
       HttpWRequest.ContentLength = sQuery.Length;
   
       //Set the request timeout to 5 minutes.
       HttpWRequest.Timeout = 300000;
       // Set the request method.
       HttpWRequest.Method = "PUT";
   
       // Store the data in a byte array.
       byte[] ByteQuery = System.Text.Encoding.ASCII.GetBytes(sQuery);
       HttpWRequest.ContentLength = ByteQuery.Length;
       Stream QueryStream = HttpWRequest.GetRequestStream();
       // write the data to be posted to the Request Stream
       QueryStream.Write(ByteQuery,0,ByteQuery.Length);
       QueryStream.Close();
   
       // Send the request and get the response.
       HttpWebResponse HttpWResponse = (HttpWebResponse)HttpWRequest.GetResponse();
   
       // Get the Status code.
       int iStatCode =  (int)HttpWResponse.StatusCode;
       string sStatus = iStatCode.ToString();
       Console.WriteLine("Status Code: {0}", sStatus);
       // Get the request headers.
       string sReqHeaders = HttpWRequest.Headers.ToString();
       Console.WriteLine(sReqHeaders);
   
       // Read the response stream.
       Stream strm = HttpWResponse.GetResponseStream();
       StreamReader sr = new StreamReader(strm);
       string sText = sr.ReadToEnd();
       Console.WriteLine("Response: {0}", sText);
   
       // Close the stream.
       strm.Close();
   
       // Clean up.
       myCred = null;
       myCredentialCache = null;
       HttpWRequest = null;
       HttpWResponse = null;
       QueryStream = null;
       strm = null;
       sr = null;
      }
      catch (Exception e)
      {
       Console.WriteLine("{0} Exception caught.", e);
