I have seen the difference between pst and ost files and currently working on accessing the outlook pst file through the following code given below. Is there any way to use the same code for accessing ost file? Can someone refer me to this?

private DataTable GetInboxItems()
{
    DataTable inboxTable;
    //try
    //{
    filter = "[ReceivedTime] >= '" + dtpStartDate.Value.ToString("dd/MM/yyyy 12:00 AM")   + "' and [ReceivedTime] <= '" + dtpEndDate.Value.ToString("dd/MM/yyyy  11:59 PM") + "'";
    Outlook.Application outlookApp = GetApplicationObject();
    Outlook.Folder root = outlookApp.Session.DefaultStore.GetRootFolder() as  Outlook.Folder;
    EnumerateFolders(root);
    //string filter = "[ReceivedTime] > '" + dtpStartDate.Value.ToString("dd/MM/yyyy")  + "'";

    //inbox
    Outlook.MAPIFolder inboxFolder =  outlookApp.Session.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderInbox);
    inboxTable = CreateTable();
    int count = 0;


    if (inboxFolder.Items.Count > 0)
    {

        var restrictedItems = inboxFolder.Items.Restrict(filter);
        restrictedItems.Sort("[ReceivedTime]", true); //descending
        //foreach (var item in inboxFolder.Items)
        foreach (var item in restrictedItems)
        {
            var mail = item as Outlook.MailItem;
            if (mail != null)
            {
                //try
                //{
                DataRow row = inboxTable.NewRow();
                //row["sn"] = (++count).ToString();
                row["sn"] = mail.EntryID + " " + mail.ReceivedByEntryID;
                row["MailType"] = "Inbox";
                row["SenderName"] = mail.SenderName;
                row["SenderEmail"] = mail.SenderEmailAddress;
                row["ReceivedDate"] = mail.ReceivedTime;
                row["Subject"] = mail.Subject;
                row["Body"] = mail.Body != null ? (mail.Body.Length > 25 ?  mail.Body.Substring(0, 25) : mail.Body) : null;
                //row["Body"] = mail.Body != null ? mail.Body : "";
                row["MailSize"] = mail.Size.ToString();
                string attachments = null;
                if (mail.Attachments.Count > 0)
                {
                    foreach (var attachment in mail.Attachments)
                    {
                        if (((Outlook.Attachment)attachment) != null)
                            //attachments = ((Outlook.Attachment)attachment).FileName +  " " + ((Outlook.Attachment)attachment).Size.ToString() + ", ";
                            attachments += (((Outlook.Attachment)attachment).Size / 1024).ToString() + " KB, ";
                    }
                }


                row["AttachmentCount"] = mail.Attachments.Count;
                if (attachments != null)
                    row["AttachmentSize"] = attachments.Substring(0, attachments.Length - 2);

                inboxTable.Rows.Add(row);
            }
            //catch (Exception ex)
            //{

            //    return null;
            //}

        }
    }

    return inboxTable;
}

推荐答案

您需要对OST/PST进行了解，因为对它们的访问没有太大区别，两者都是

You need to educate yourself on what OST/PST is as the access to them is not much different, both are Store objects so they have the same interface.
