我正在开发一个软件,我可以在其中检索收件箱并从 Outlook 发送项目。我想要做的是将收件箱电子邮件与回复联系起来(如果有人回复了该电子邮件)。列表应按此顺序显示
Sender@abc.com 接收主题接收时间 sender@abc.com 回复主题 发送时间
我打算做的是检索一个数据表中的收件箱项目和另一个数据表中的已发送项目。它根据发件人电子邮件和主题逐一读取电子邮件,然后在已发送项目中搜索该发件人和电子邮件,如果匹配,则将其合并到第三个数据表中。
还有其他更好的方法吗?
这是代码:
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;
}
