推荐答案
使用此方法
Use this method
public static string RenderControl(Control ctrl)
{
StringBuilder sb = new StringBuilder();
StringWriter tw = new StringWriter(sb);
HtmlTextWriter hw = new HtmlTextWriter(tw);
ctrl.RenderControl(hw);
return sb.ToString();
}
和通话功能为
and call function as
Msg.Body += RenderControl(datalist1);
希望它能解决您的问题。
