Getting null value for NotesDocument for Mail Item : C#

Question

Hi,

I am accessing From value of each mail from nsf file. As:

NotesView sent = _NotesDatabase.GetView("($Sent)");

if (sent != null)

{

NotesDocument docSent = sent.GetFirstDocument();

if (docSent != null)

{

   while (docSent != null)

   {

    String Subject = ( (object[]) DocSent.GetItemValue("Subject"))[0] as String;

    Message.Show(Subject);

    docSent = sent.GetNextDocument(docSent);    

   }//while

}

}

But there are some mails for which i am getting "null" value (it contains SendTo,Subject e.t.c values: viewed in lotus notes).

So i can't access Subject of it. Why it is happening? i checked Form value it is "Memo"

If you're getting a null value from GetItemValue, then the field is probably not on the document. You can check for this condition using the HasItem method of the NotesDocument class, as in:

if (docSent.hasItem("Subject")) {
    ...
}
