LumiSoft.Net.IMAP收邮件问题
我用LumiSoft.Net.IMAP收邮件时，为何未读邮件没有变为已读啊？怎么才能让读取未读邮件时，会改变为已读呢？或者删掉算了。求告诉帮帮忙啊！！感激不尽
部分代码：
/// <summary>
/// 根据邮件编号返回邮件内容
/// </summary>
/// <param name="uid">邮件编号</param>
/// <returns>成功返回邮件内容，失败返回空字符串</returns>
public string LoadMessage(long uid)
{
try
{
/* NOTE: IMAP_Client_FetchHandler provides events to handle IMAP server returned
* fetch data items for requested message(s).
*/
string html = "";
IMAP_Client_FetchHandler fetchHandler = new IMAP_Client_FetchHandler();
fetchHandler.Rfc822 += new EventHandler<IMAP_Client_Fetch_Rfc822_EArgs>(delegate(object s, IMAP_Client_Fetch_Rfc822_EArgs e)
{
MemoryStream storeStream = new MemoryStream();
e.Stream = storeStream;
e.StoringCompleted += new EventHandler(delegate(object s1, EventArgs e1)
{
storeStream.Position = 0;
Mail_Message mime = Mail_Message.ParseFromStream(storeStream);
//this.tmimin.Tag = mime;
//m_pTabPageMail_MessageAttachments.Tag = mime;
foreach (MIME_Entity entity in mime.Attachments)
{
//ListViewItem item = new ListViewItem();
if (entity.ContentDisposition != null && entity.ContentDisposition.Param_FileName != null)
{
//this.tmimin.Text += "附件：" + entity.ContentDisposition.Param_FileName;
}
else
{
//this.tmimin.Text += "附件： untitled";
}
//item.ImageIndex = 0;
//item.Tag = entity;
//m_pTabPageMail_MessageAttachments.Items.Add(item);
}
if (mime.BodyHtmlText != null)
{
html = mime.BodyHtmlText;
}
else if (mime.BodyText != null)
{
html = mime.BodyText;
}
else
{
html = "";
}
});
});
IMAP_SequenceSet seqSet = new IMAP_SequenceSet();
seqSet.Parse(uid.ToString());
// Start fetching (IMAP_Client_FetchHandler events are rised when IMAP server returns any data).
this.imap.Fetch(
true,
seqSet,
new IMAP_Fetch_DataItem[]{
new IMAP_Fetch_DataItem_Rfc822()
},
fetchHandler
);
return html;
}
catch //(Exception x)
{
return "";
//MessageBox.Show(this, "Error: " + x.ToString(), "Error:", MessageBoxButtons.OK, MessageBoxIcon.Error);
}
}
