本文的需求来自进来SharePoint开发中的人员选择，基础中国的用户更加喜欢通过组织结构来选择人员，这样可以清晰的知道选择人员的部门，通过组织结构选择人员是本文的讨论点。 我也是集合了前人的思路，进行了整合，参考了下面的博客 基于AD的用户组织目录树选择工具的解决方案 asp.net(C#)弹出窗口返回值并刷新主窗体 使用C＃中的DirectorySearcher来获得活动目录中的组织结构与用户等信息，并在展示成树形结构(附源代码) 感谢三位作者的无私奉献，为我的这篇博客提供了资料。 我的整个实现是由三个页面组成，首先是一个信息填写页面WebForm1.aspx，有一栏为选择任务的执行人员 
WebForm1.aspx页面代码如下 
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="WebApp.WebForm1" %><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml" ><head runat="server"> <title>无标题页</title> <style type="text/css"> body { font-size:12px; } </style></head><body> <form id="form1" runat="server"> <div> <table style="width: 100%;"> <tr> <td style="width:100px;"> 任务标题:</td> <td> <asp:TextBox ID="TextBox2" runat="server" Width="500px"></asp:TextBox> </td> </tr> <tr> <td style="width:100px;"> 任务内容:</td> <td> <asp:TextBox ID="TextBox3" runat="server" Height="117px" TextMode="MultiLine" Width="500px"></asp:TextBox> </td> </tr> <tr> <td style="width:100px;"> 代办人:</td> <td> <asp:TextBox ID="TextBox1" runat="server" Width="500px">这是初始值，将被传递到新窗口。</asp:TextBox> <asp:Button ID="Button1" runat="server" Text="打开窗口" Width="96px" οnclick="Button1_Click" /> </td> </tr> </table> </div> </form></body></html> WebForm1.aspx的后台代码如下 using System;using System.Collections;using System.Configuration;using System.Data;using System.Linq;using System.Web;using System.Web.Security;using System.Web.UI;using System.Web.UI.HtmlControls;using System.Web.UI.WebControls;using System.Web.UI.WebControls.WebParts;using System.Xml.Linq;namespace WebApp{ public partial class WebForm1 : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { if (!ClientScript. IsClientScriptBlockRegistered("clientScript")) { System.Text.StringBuilder sbScript = new System.Text.StringBuilder(); sbScript.Append("<script>"); sbScript.Append("function OpenWin(){"); sbScript.Append(Environment.NewLine); sbScript.Append("var str=window.showModalDialog('WebForm2.aspx',document.form1.TextBox1.value,'dialogWidth=800px;dialogHeight=700px','scroll:yes');"); sbScript.Append(@"if(str!=null) { var users=str; document.form1.TextBox1.value=users.substring(0,users.lastIndexOf(',')); } "); sbScript.Append("}"); sbScript.Append("</script>"); ClientScript. RegisterClientScriptBlock(this.GetType(),"clientScript", sbScript.ToString()); } Button1.Attributes.Add("onclick", "OpenWin()"); } protected void Button1_Click(object sender, EventArgs e) { } }} 弹出窗口如下图，是用一个页面，里面嵌套一个iframe，防止回发之后页面消失WebForm2.aspx嵌套 ADOperTest.aspx

这个东西本来是SharePoint开发过程中出来的需求，可是返回的只是一个组合了用户姓名的字符串，不能变成SPUser对象，SPUser对象又没有构造函数，有没有研究过这个呢，如果有的话，可以给我留言，谢谢了。
