If the item has an attachment it will save it to the path specified.
To begin with Add a Outlook interop assembly to the reference in the project
Once added please copy paste the below code to run the sample
Code Snippet
- try
- {
- Microsoft.Office.Interop.Outlook.Application MyApp = new Microsoft.Office.Interop.Outlook.Application();
- Microsoft.Office.Interop.Outlook.NameSpace MailNS = MyApp.GetNamespace("mapi");
- MailNS.Logon(MyApp.DefaultProfileName, Missing.Value, false, true);
- Microsoft.Office.Interop.Outlook.MAPIFolder MyInbox = null;
- MyInbox = MailNS.GetDefaultFolder(Microsoft.Office.Interop.Outlook.OlDefaultFolders.olFolderInbox);
- Microsoft.Office.Interop.Outlook._MailItem InboxMailItem = null;
- Microsoft.Office.Interop.Outlook.Items oItems = MyInbox.Items;
- ////string Query = "[Subject] = '" + Properties.Settings.Default.EmailSubject + "'";
- string Query = "[Subject] = 'my sample search text'";
- InboxMailItem = (Microsoft.Office.Interop.Outlook._MailItem)oItems.Find(Query);
- while (InboxMailItem != null)
- {
- ListViewItem myItem = lvwMails.Items.Add(InboxMailItem.SenderName);
- myItem.SubItems.Add(InboxMailItem.Subject);
- string AttachmentNames = string.Empty;
- foreach (Microsoft.Office.Interop.Outlook.Attachment item in InboxMailItem.Attachments)
- {
- AttachmentNames += item.DisplayName;
- ////item.SaveAsFile(this.GetAttachmentPath(item.FileName, Properties.Settings.Default.ReceiveAttachmentPath));
- item.SaveAsFile(this.GetAttachmentPath(item.FileName, "c:\\test\\attachments\\"));
- }
- myItem.SubItems.Add(AttachmentNames);
- InboxMailItem.Delete();
- InboxMailItem = (Microsoft.Office.Interop.Outlook._MailItem)oItems.FindNext();
- }
- ////MailMsg.Send();
- MailNS.Logoff();
- MailNS = null;
- MyInbox = null;
- InboxMailItem = null;
- ((Microsoft.Office.Interop.Outlook._Application)MyApp).Quit();
- ////MyApp.Quit();
- MyApp = null;
- }
- catch (Exception ex)
- {
- MessageBox.Show(ex.Message);
- }
the getattachmentpath method implementation is below. This method will check for any existing attachment with the same name and adds running number if exists
Code Snippet
- private string GetAttachmentPath(string AttachfileName, string AttachPath)
- {
- string filename = Path.GetFileNameWithoutExtension(AttachfileName);
- string ext = Path.GetExtension(AttachfileName);
- int app = 0;
- if (File.Exists(AttachPath + filename + ext))
- {
- while (File.Exists(AttachPath + filename + app + ext))
- {
- app++;
- }
- filename = filename + app;
- }
- return AttachPath + filename + ext;
- }
