windowsphone socket聊天

private void OutputMessage(string data)
{

// 在聊天文本框中输出指定的信息，并将滚动条滚到底部
this.Dispatcher.BeginInvoke(
delegate
{
chatmessage.Items.Add(tblock.Text + DateTime.Now.ToShortTimeString() + "\r\n" + data + "\r\n");
//chatmessage.Items.Add( data + "\r\n");

}
);
}
为什么使用chatmessage.Items.Add(tblock.Text + DateTime.Now.ToShortTimeString() + "\r\n" + data + "\r\n");服务器转发会发很多空信息
而使用chatmessage.Items.Add( data + "\r\n");就不会。

你debug了吗？看看data里面的结果是否一样？如果一样，那么就在转发的过程中第一条add的值(tblock.Text)存在某些服务器的关键字，被疲敝了。最好的办法就是debug。不过，你的意思是偶尔会出现空信息？还是只要用第一个add就会出现空信息？

引用 3 楼 littleluoron 的回复:

你可以尝试一下把第一条的replace("\r\n","#")之后，到了server再replace("#","\r\n")试试。我觉得可能是不能有\r\n。但是好像我的软件用Socket没有这个情况。所以我就不太清楚你的了不过，能否把两个add的值写出来？俺分析分析
