how to retrive emails from outlook in asp.net c#?

i tried below code but it's not working.

try

{

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)

{

Console.WriteLine(ex.ToString());

}

finally

{

ns = null;

app = null;

inboxFolder = null;

}
