MORE INFORMATION

Sample

1. Start Microsoft Visual Studio .NET or Microsoft Visual Studio 2005.
2. On the File menu, click New, and then click Project.
3. Select Console Application from the Visual C# Projects types. By default, Class1.cs is created in Visual Studio .NET. Program.cs is created in Visual Studio 2005.
4. In the code window, replace the whole 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 
         {
           /*
           'strFolderType    Name
           '
           'MailItems        IPF.Note
           'ContactItems     IPF.Contact
           'AppointmentItems IPF.Appointment
           'NoteItems        IPF.StickyNote
           'TaskItems        IPF.Task
           'JournalItems     IPF.Journal
           */ 
   
           // TODO: Replace with the URL of an object on Exchange Server
           string sUri = "http://ExchServer/Exchange/Administrator/Inbox/NewApptFolder";
     
           System.Uri myUri = new System.Uri(sUri);
           HttpWebRequest HttpWRequest = (HttpWebRequest)WebRequest.Create(myUri);
   
           string sQuery;
           sQuery = "<?xml version='1.0'?>" + 
             "<a:propertyupdate xmlns:a='DAV:' " + 
             "xmlns:ex='http://schemas.microsoft.com/exchange/'>" + 
             "<a:set><a:prop>" + 
             "<ex:outlookfolderclass>IPF.Appointment</ex:outlookfolderclass>" + 
             "</a:prop></a:set>" + 
             "</a:propertyupdate>";
   
           // Set Credentials
           // TODO: Replace with appropriate user credentials
           NetworkCredential myCred = new NetworkCredential(@"DomainName\UserName", "UserPassword");
           CredentialCache myCredentialCache = new CredentialCache();
           myCredentialCache.Add(myUri, "Basic", myCred);
           HttpWRequest.Credentials = myCredentialCache;
   
           // Set Headers
           HttpWRequest.KeepAlive = false; 
           HttpWRequest.Headers.Set("Pragma", "no-cache");
           HttpWRequest.ContentType =  "text/xml";
           HttpWRequest.ContentLength = sQuery.Length;
   
           //Set the request timeout to 5 minutes
           HttpWRequest.Timeout = 300000;
           // Set the request method
           HttpWRequest.Method = "MKCOL";
   
           // 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 Request and Get 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 Steam
           Stream strm = HttpWResponse.GetResponseStream();
           StreamReader sr = new StreamReader(strm);
           string sText = sr.ReadToEnd();
           Console.WriteLine("Response: {0}", sText);
   
           // Close 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);
         }
       }
     }
   
   }

5. Modify the code wherever you see "TODO".
