How to list all fields of an object by using Collaboration Data Objects for Exchange 2000 Server Library in Visual C#

Create the Sample to List All Fields of an Object

1. Start Microsoft Visual Studio .NET or Microsoft Visual Studio 2005.
2. On the File menu, click New, and then click Project.
3. Click Visual C# Projects, and then double-click Console Application from the Visual C# Projects types. By default, Class1.cs is created.
   
   Note In Visual Studio 2005, click Visual C# under Project Types. In Visual Studio 2005, Program.cs is created by default.
4. Add a reference to the MDO for Exchange 2000 Library and the Microsoft ActiveX Data 2.5 Library. To do so, follow these steps:
   1. On the Project menu, click Add Reference.
   2. Click the COM tab, click Microsoft CDO for Exchange 2000 Library in the Component Name, and then click Select.
   3. Click Microsoft ActiveX Data Objects 2.5 Library in the Component Name list, and then click Select.
      
      Note In Visual Studio 2005, you do not have to click Select.
   4. Click OK. If you are prompted to generate wrappers for the libraries that you selected, click Yes.
5. In the Code window, replace the default code with the following code:

   using System;
   
   namespace Samples
   {
   	class Class1
   	{
   		static void Main(string[] args)
   		{
   			try 
   			{
   			ADODB.Connection oCn = new ADODB.Connection();
   			ADODB.Record oRc= new ADODB.Record();
   
   			ADODB.Fields oFields;
   			ADODB.Field oField;
   
                           // TODO: Replace with your folder 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");
   			}
   
   			oRc.Open(sFdUrl, oCn, 
   				ADODB.ConnectModeEnum.adModeReadWrite, 
   				ADODB.RecordCreateOptionsEnum.adFailIfNotExists,
   				ADODB.RecordOpenOptionsEnum.adOpenSource,
   				"", "");
   
   			
   			oFields = oRc.Fields;
   
   			for(int i = 0; i < oFields.Count; i++)
   			{
   				oField = oFields[i];
   				Console.WriteLine("{0} : {1}", oField.Name, oField.Value);
   			}
   
   			oRc.Close();
   			oCn.Close();
   
   			oCn = null;
   			oRc = null;
   			oFields = null;
   			oField = null;
   			}
   			catch (Exception e)
   			{
   				Console.WriteLine("{0} Exception caught.", e);
   			}			
   		}
           }
   }
