How to get Attachment value from “$File” Item? using C# (Lotus Notes)

问题

I am trying to access Attachment names form "$File" (Lotus Notes).

 NotesView inbox = _serverDatabase.GetView("($Inbox)");
 NotesDocument docInbox = inbox.GetFirstDocument(); 

 NotesItem file = docInbox.GetFirstItem("$File");

 String fileType = file.type.ToString();

( getting fileType value "ATTACHMENT" for mail containing attachments)

I am not getting solution given in:

How to Access attachments from Notes mail?

I got solution as:

object[] items = (object[])docInbox.Items; 

foreach (NotesItem nItem in items)

{

  if (nItem.Name == "$FILE")
   {

     NotesItem file = docInbox.GetFirstItem("$File");   

     string fileName = ((object[])nItem.Values) [0].ToString();

     NotesEmbeddedObject attachfile = (NotesEmbeddedObject)docInbox.GetAttachment(fileName);

     if (attachfile != null)
      {
        attachfile.ExtractFile("C:\\test\\" + fileName);
      }
 }

But here I am getting only first attachment value. Can anyone help me out in this?

Try something like this:

    NotesView inbox = _serverDatabase.GetView("($Inbox)"); 
    NotesDocument docInbox = inbox.GetFirstDocument();  
    if(docInbox.HasEmbedded )   {
       foreach (NotesEmbeddedObject o in docInbox.EmbeddedObjects) {
           if ( o.Type == 1454 ) {
            o.ExtractFile( "c:\samples\" & o.Source )    
    }
   }
}

Here is a link to Lotus Notes Designer Help - Really good as you can search for Classes etc to find out what options you have.

Show you all the methods and properties of various class.

Hi Preeti,

OK from the other code sample you are returning an array:

string fileName = ((object[])nItem.Values) [0].ToString();

Yet you are only selecting the first value, you need to recurse through the collection.

Try something like this.

foreach (object attachment in (object[])nItem.Values)
        {
            NotesEmbeddedObject attachfile = (NotesEmbeddedObject)docInbox.GetAttachment(attachment.ToString());

            if (attachfile != null)
            {
                attachfile.ExtractFile("C:\\test\\" + attachment.ToString());
            }

        }

Your above code snippet is very helpful to me. So, I tried the to save all attachments and finally found the below solution.

            NotesView nInboxDocs = NDb.GetView("$Inbox");
            NDoc=nInboxDocs.GetFirstDocument();
            while (NDoc != null)
            {
                if (NDoc.HasEmbedded && NDoc.HasItem("$File"))
                {
                    // To save only first attachment //
                    //pAttachment = ((object[])NDoc.GetItemValue("$File"))[0].ToString();
                    //pAttachment = CurItem.ToString();
                    //NDoc.GetAttachment(pAttachment).ExtractFile(@"C:\Documents and Settings\Administrator\Desktop\" + pAttachment);

                    // To save all attachment //
                    object[] AllDocItems = (object[])NDoc.Items;
                    foreach (object CurItem in AllDocItems)
                    {
                        NotesItem nItem = (NotesItem)CurItem;
                        if (IT_TYPE.ATTACHMENT == nItem.type)
                        {
                            pAttachment = ((object[])nItem.Values)[0].ToString();
                            NDoc.GetAttachment(pAttachment).ExtractFile(@"C:\Documents and Settings\Administrator\Desktop\" + pAttachment);
                        }
                    }
                }
                NDoc = nInboxDocs.GetNextDocument(NDoc);
            }
