MORE INFORMATION

To use the Outlook 2002 Object Library or the Outlook 2003 Object Library to retrieve a message from the Inbox by using Visual C#, follow these steps:

In Microsoft Visual Studio .NET or Visual Studio 2005, create a new Console Application project:
1. On the File menu, point to New, and then click Project.
2. Under Project Types, click Visual C# Projects.
  
  Note In Visual Studio 2005, click Visual C#.
3. Under Templates, click Console Application.
4. Click OK. By default, a file that is named Class1.cs is created.
  
  Note In Visual Studio 2005, Program.cs is created by default.
Add a reference to either the Outlook 2002 Object Library or the Outlook 2003 Object Library. To do this, follow these steps:
1. On the Project menu, click Add Reference.
2. Click the COM tab.
3. On the COM tab, click Microsoft Outlook 11.0 Object Library if you are using Outlook 2003, or click Microsoft Outlook 10.0 Object Library if you are using Outlook 2002.
4. Click Select.
5. In the Add References dialog box, click OK.
  
  Note If you receive a message to generate wrappers for the libraries that you selected, click Yes.

In the Class1.cs code window, replace all the existing code with the following code:

using System;
using System.Reflection; // to use Missing.Value

//TO DO: If you use the Microsoft Outlook 11.0 Object Library, uncomment the following line.
//using Outlook = Microsoft.Office.Interop.Outlook;


namespace ConsoleApplication1
{
	public class Class1
	{
		public static int Main(string[]args)
		{
			try
			{
				// Create the Outlook application.
				// in-line initialization
				Outlook.Application oApp = new Outlook.Application();

				// Get the MAPI namespace.
				Outlook.NameSpace oNS = oApp.GetNamespace("mapi");

				// Log on by using the default profile or existing session (no dialog box).
				oNS.Logon(Missing.Value,Missing.Value,false,true);

				// Alternate logon method that uses a specific profile name.
				// TODO: If you use this logon method, specify the correct profile name
				// and comment the previous Logon line.
				//oNS.Logon("profilename",Missing.Value,false,true);

				//Get the Inbox folder.
				Outlook.MAPIFolder oInbox = oNS.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderInbox);

				//Get the Items collection in the Inbox folder.
				Outlook.Items oItems = oInbox.Items;

				// Get the first message.
				// Because the Items folder may contain different item types,
				// use explicit typecasting with the assignment.
				Outlook.MailItem oMsg = (Outlook.MailItem)oItems.GetFirst();

				//Output some common properties.
				Console.WriteLine(oMsg.Subject);
				Console.WriteLine(oMsg.SenderName);
				Console.WriteLine(oMsg.ReceivedTime);
				Console.WriteLine(oMsg.Body);

				//Check for attachments.
				int AttachCnt = oMsg.Attachments.Count;
				Console.WriteLine("Attachments: " + AttachCnt.ToString());
				
				//TO DO: If you use the Microsoft Outlook 10.0 Object Library, uncomment the following lines.
				/*if (AttachCnt > 0) 
				{
					for (int i = 1; i <= AttachCnt; i++) 
						 Console.WriteLine(i.ToString() + "-" + oMsg.Attachments.Item(i).DisplayName);
				}*/
								
				//TO DO: If you use the Microsoft Outlook 11.0 Object Library, uncomment the following lines.
				/*if (AttachCnt > 0) 
				{
					for (int i = 1; i <= AttachCnt; i++) 
						 Console.WriteLine(i.ToString() + "-" + oMsg.Attachments[i].DisplayName);
				}*/

								
				//Display the message.
				oMsg.Display(true);  //modal

				//Log off.
				oNS.Logoff();

				//Explicitly release objects.
				oMsg = null;
				oItems = null;
				oInbox = null;
				oNS = null;
				oApp = null;
			}

				//Error handler.
			catch (Exception e)
			{
				Console.WriteLine("{0} Exception caught: ", e);
			}

			// Return value.	
			return 0;
