C# .NET - outlook problem in windows application

hi,

tryt the below 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;

try
{
  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)
{
  Console.WriteLine(ex.ToString());
}
finally
{
  ns = null;
  app = null;
  inboxFolder = null;
}

To use outlook in c# we have to instantiate the Outlook Application object. We are referring the outlook name space couple of times .so, rename outlook name space rename like this.

First we have to create outlook application interface object.

Add outlook COM object reference to your windows app,

using Outlook = Microsoft.Office.Interop.Outlook;

Then you should be able to instantiate an Outlook object and make requests of it:

Outlook.Application app = new Outlook.ApplicationClass();
Outlook.NameSpace NS = app.GetNamespace("MAPI");
Outlook.MAPIFolder inboxFld = NS.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderInbox);
 
This will give you access to inboxFld, which will allow you to iterate through the contents of the inbox! You can also change this to iterate through notes, or through calendar entries, tasks, etc. as you want.

For example, to iterate through your mail you can do:

foreach(Outlook.MailItem t in inboxFld.Items)
{
 Now you can loop through the attachments as,

    foreach(Outlook.Attachment Atmt in t.Attachments){
       'save the attachment to some filename, just for ex., c:\test.doc
        Atmt.SaveAsFile "C:\test.doc"
    }

}

Try this part of code, its in vb, convert to c#

Dim _objItem As Outlook.MailItem = Nothing
Dim _objInboxFolder As Outlook.MAPIFolder = Nothing
Dim _objSubfolder As Outlook.MAPIFolder
Dim _outlook As Outlook.MailItemClass
Dim _outlookObj As New Outlook.Application
Dim _outlookNamespace As Outlook.NameSpace
_outlookNamespace = _outlookObj.GetNamespace("MAPI")
_outlookNamespace.Logon(Nothing, Nothing, False, False)
_objInboxFolder = _outlookNamespace.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderInbox)
_objSubfolder = _objInboxFolder.Folders(1);

console.Write("Folder Name: " & _objSubfolder.Name & " Entry ID" & _objSubfolder.EntryID)
console.Write("Num Items: " & _objSubfolder.Items.Count)
Dim _itemCount As Integer = _objSubfolder.Items.Count
While (_itemCount <> 0)
_objItem = CType(_objSubfolder.Items(_itemCount), Outlook.PostItem)
console.Write("Item " & _objItem.Subject.ToString)
_itemCount -= 1
End While

Outlook.Application app = new Outlook.ApplicationClass();

Outlook.NameSpace NS = app.GetNamespace("MAPI");

Outlook.MAPIFolder inboxFld = NS.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderInbox);

This will give you access to inboxFld, which will allow you to iterate through the contents of the inbox!  You can also change this to iterate through notes, or through calendar entries, tasks, etc. as you want.

For example, to iterate through your mail you can do:

Console.WriteLine(t.Subject);

}

using OutLook = Microsoft.Office.Interop.Outlook;
