正好这段时间在研究这个功能，还是得感谢这位大神，没有他的引路，我就不可能把站内信做出来。
http://www.cnblogs.com/grenet/archive/2010/03/08/1680655.html
哈哈，再次感谢。
我们先来说说单点传送站内信，所谓的单点传送，就是用户与用户之间的短信发送，这里的用户可以是一个人，也可以是多个人，
上面的文章大家如果看了的话，想必有一个疑问，就是用户的阅读状态怎么定义？
我这里给大家一种解决方案，再建立一张表，也就是说，建立一张用户阅读状态表，因为每个用户的阅读状态都是不同的，如果照上面的方法，
肯定是不行的，一个人改变了状态，另外的人也改变了。
上面的是我建立的3张表，具体的SQL如下，包含注释
--短信表 create table cms_message ( id varchar(50) primary key, senduserid varchar(50), --发送用户的ID recuserid varchar(50), --接收用户的ID messageid varchar(50), --短信ID Msgstatus varchar(10) --查看状态（是否被查询） ) --短信内容表 create table cms_messagetext ( idc varchar(50) primary key, messagetext text, --站内信内容 pdate varchar(50) --站内信发送时间 ) --阅读状态表 create table cms_message_read ( uniqueid varchar(50) primary key, idm varchar(50) ,--和MESSAGEID相同 userid varchar(50), --用户ID flag varchar(5) --阅读状态：0未读，1：已读，2：删除 )
大家也许会问一个问题，你已经在阅读状态表里定义了阅读状态，为什么还要短信表里再定义一次呢？这个其实是有用的，尤其是在发件箱功能里要标记自己的信件的时候，稍后会提到哦。
先让大家来看看主界面。
其中有发件箱，未读信息和已读消息。
发件箱的功能就是查看自己已经发送的信件，未读和已读信息就是表示自己是否已经点击过短信。
下面给大家来看一下发送短信的界面。
下面是普通的点对点发送。
下面是短信群发的界面，我这里的群发是选择发送给某个用户组。
我先把代码都放出来，然后我们再来慢慢分析。
其中有用到公司的框架，大家知道意思就行，没必要过分纠结。
这是发送短信的窗口的代码

Send.aspx.cs
下面我们就来详细解释一下代码，首先我们要知道一件事情，就是：我给很多人发了同一条信息，然后有的人看过了，有的人没有看，所以就有不同的状态，
而这种不同的状态，是以一个用户名+短信ID来确定的一个唯一的值。
明白这点就好办了。而删除也不是真正的删除，而是改变阅读的状态，让它查询不到。
还有一点大家要注意，就是怎么实现：点一下短信，让短信变成已读，这个问题困扰了我很久，因为这个链接是在GRIDVIEW里面。
我们其实只要用这个链接的ONCLICK事件，然后跳到前台，从前台去改变数据库里的值就行了。
如下：
function winOpens(id)
{
//return winOpen( 450 , 370 , "新增短信" , "MsgSend/AdminSend.aspx?id="+id );
<%
//更新状态表
bool flag = this.DataManager.Execute("update cms_message_read set flag=1 where idm=‘" + ids.Value + "‘ and userid=‘" + idsUser.Value + "‘");
// Response.Write(flag);
%>
window.showModalDialog( "AdminSend.aspx?id="+id ,"查询短信","dialogWidth=450px;dialogHeight=370px");
}
这样就OK了。
还有一点大家要注意一下，就是发件箱的删除功能和未读已读是2个不同的概念，因为发件箱里查询到的是自己的信息，
而未读，已读，是在状态表里存放的状态，这就是为什么发件箱里面也要有一个阅读状态的列，其作用就是：判断是否删除（假删）。
而要改变未读，已读里的状态，先要找到状态表里的ID，ID怎么找，找唯一项，唯一项，就是短信ID+用户名的组合。
如下。
//未读信息删除方法(假删)
protected void delMsg_UnRead(object sender,EventArgs e)
{
string[] ids = this.txtIDS.Value.Split(new string[] { "," }, StringSplitOptions.RemoveEmptyEntries);
//方法：先是找到对应的的一张表的ID，然后根据用户名找到第三张表对应的UniqueID,根据UNIQUEID进行UPDATE操作
//第一张表：cms_message ，第三张表：cms_message_read
string ids_Package = "";
for (int i = 0; i < ids.Length; i++)
{
ids_Package += ",‘" + ids[i] + "‘";
}
DataSet setUnread_Dels = this.DataManager.Fill("select c.uniqueid from cms_message a,cms_messagetext b,cms_message_read c where a.messageid=b.idc and c.idm=b.idc and c.flag=0 and c.userid=‘" + cms.Web.AppContext.CuurentUser.ID + "‘ and a.id in("+ids_Package.Substring(1)+")");
foreach (DataRow Row in setUnread_Dels.Tables[0].Rows)
{
//更新数据库
string update_Sql = "update cms_message_read set flag=2 where uniqueid=‘" + Row["uniqueid"].ToString() + "‘";
this.DataManager.Execute(update_Sql);
}
}
站内信关键是思路上的问题，其实并不是很难。
