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
WebForm1.aspx<%@ 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=" 100%;">
<tr>
<td style="100px;">
任务标题:</td>
<td>
<asp:TextBox ID="TextBox2" runat="server" Width="500px"></asp:TextBox>
</td>
</tr>
<tr>
<td style="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="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"
onclick="Button1_Click" />
</td>
</tr>
</table>
</div>
</form>
</body>
</html>
WebForm1.aspx的后台代码如下
WebForm1.aspx.csusing 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
WebForm2.aspx页面文件，没有后台代码
WebForm2.aspx<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm2.aspx.cs" Inherits="WebApp.WebForm2" %>
<!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>
<iframe src="ADOperTest.aspx" id="iframe1" width="1600px" height="1400px"></iframe>
</body>
</html>
后台代码

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。
