How to receive e-mails with c#


I want to pull emails from outlook to an c# application, process them and send it to a folder or a email-address.

How can this be done? I have no problem with sending an e-mail directly from c#.

The following demostrates how to retreive data from items within an Outlook folder (called "MySubFolderName" under the Inbox folder) using .NET:

First add a reference to the Outlook COM object your project:

In VS.NET right click on References and choose Add Reference.
Select the COM tab
Choose "Microsoft Outlook 11.0 Object Library" (this is for MS Office 2003 - I think 10.0 is for Office XP) and click Select.
Click OK.
Note that you can access any Outlook/Exchange object types, eg Appointments, Notes, Tasks, Emails etc - just use intellisense to select which one (eg Microsoft.Office.Interop.Outlook. ... - see definition of variable called 'item' below).

Here's the code:

Microsoft.Office.Interop.Outlook.Application app = null;
Microsoft.Office.Interop.Outlook._NameSpace ns = null;
Microsoft.Office.Interop.Outlook.PostItem item = null;
Microsoft.Office.Interop.Outlook.MAPIFolder inboxFolder = null;
Microsoft.Office.Interop.Outlook.MAPIFolder subFolder = null;

  app = new Microsoft.Office.Interop.Outlook.Application();
  ns = app.GetNamespace("MAPI");
  ns.Logon(null,null,false, false);

  inboxFolder = ns.GetDefaultFolder(Microsoft.Office.Interop.Outlook.OlDefaultFolders.olFolderInbox);
  subFolder = inboxFolder.Folders["MySubFolderName"]; //folder.Folders[1]; also works
  Console.WriteLine("Folder Name: {0}, EntryId: {1}", subFolder.Name, subFolder.EntryID);
  Console.WriteLine("Num Items: {0}", subFolder.Items.Count.ToString());

  for(int i=1;i<=subFolder.Items.Count;i++)
    item = (Microsoft.Office.Interop.Outlook.PostItem)subFolder.Items[i];
    Console.WriteLine("Item: {0}", i.ToString());
    Console.WriteLine("Subject: {0}", item.Subject); 
    Console.WriteLine("Sent: {0} {1}" item.SentOn.ToLongDateString(), item.SentOn.ToLongTimeString());
    Console.WriteLine("Categories: {0}", item.Categories);
    Console.WriteLine("Body: {0}", item.Body);
    Console.WriteLine("HTMLBody: {0}", item.HTMLBody); 
catch (System.Runtime.InteropServices.COMException ex) 
  ns = null;
  app = null;
  inboxFolder = null;

Will this "listen" to my mailbox an pull the emails automaticly, or do I have to use a button or something to pull them out?

Imran Javed ZiaConsultant Software Engineer - .NET ArchitectCommented:
Sure, you have initiate some event to do so, alternatively you have to write some window service to manage it
If you want to do on click event then put all the logic in that event. If you want to implement on some form/page loading then add in onload. But if you want to run this as process means in background silently as a service then you have to implement windows service.

Ok, I need to implement a windows service to run in the background pulling these emails when they land in my inbox 24/7.

I'll give it a try.

ok best of luck for your project
