5. In the code window, replace the code with the following:

   using System;
   
   namespace Samples
   {
   	class Class1
   	{
   		static void Main(string[] args)
   		{
   			try 
   			{
   			ADODB.Connection oCn = new ADODB.Connection();
   			ADODB.Recordset oRs = new ADODB.Recordset();
   			
   
   			ADODB.Fields oFields;
   			ADODB.Field oField;
   
                           // TODO: Replace with your folder's URL.
   			string sFdUrl = "http://ExchServer/Exchange/UserAlias/Inbox";
   			
   			oCn.Provider = "exoledb.datasource";
   			oCn.Open(sFdUrl, "", "", -1);  
   
   			if(oCn.State == 1)
   			{
   				Console.WriteLine("Good Connection");
   			}
   			else
   			{
   				Console.WriteLine("Bad Connection");
   			}
   
   
   			string strSql;
   			strSql = "";
   			strSql = "select ";
   			strSql = strSql + " \"urn:schemas:mailheader:content-class\"";
   			strSql = strSql + ", \"DAV:href\" ";
   			strSql = strSql + ", \"DAV:displayname\"";
   			strSql = strSql + " from scope ('shallow traversal of " + "\"";
   			strSql = strSql + sFdUrl + "\"') ";
   			strSql = strSql + " WHERE \"DAV:ishidden\" = false";
   			strSql = strSql + " AND \"DAV:isfolder\" = false";
   
   
   			oRs.Open(strSql, oCn,
   				ADODB.CursorTypeEnum.adOpenStatic,
   				ADODB.LockTypeEnum.adLockUnspecified, 1);
   
   
   			if(oRs.State == 1)
   			{
   				Console.WriteLine("Recordset Opened");
   			}
   			else
   			{
   				Console.WriteLine("Recordset Failed Opened");
   			}
   
   			oRs.MoveFirst();
   			while(!oRs.EOF)
   			{
   				oFields = oRs.Fields;
                                       oField = oFields["DAV:href"];
   				Console.WriteLine(oField.Value);
   
   				oField = oFields["DAV:displayname"];
   				Console.WriteLine(oField.Value);
   
   				oRs.MoveNext();  
   				                             Console.WriteLine("--------------------------");
   
   			}
   
   			oRs.Close();
   			oCn.Close();
   
   			oCn = null;
   			oRs = null;
   			oFields = null;
   			oField = null;
   			}
   			catch (Exception e)
   			{
   				Console.WriteLine("{0} Exception caught.", e);
   			}			
   		}
           }
   }
