如何获得当前登录INFOPATH用户的用户组

在表单的启动事件中插入如下的代码，就可以获得当前用户的所有用户组：

 

using Microsoft.Office.InfoPath;
using System;
using System.Xml;
using System.Xml.XPath;
using Microsoft.SharePoint;

namespace 得到用户的组
{
    public partial class FormCode
    {
        // 启用浏览器功能的表单不支持成员变量。
        // 请使用代码从 FormState 词典
        // 写入和读取这些值，如下所示:
        //
        // private object _memberVariable
        // {
        //     get
        //     {
        //         return FormState["_memberVariable"];
        //     }
        //     set
        //     {
        //         FormState["_memberVariable"] = value;
        //     }
        // }

        // 注意: 以下是 Microsoft Office InfoPath 所需的过程。
        // 可以使用 Microsoft Office InfoPath 对其进行修改。
        public void InternalStartup()
        {
            EventManager.FormEvents.Loading += new LoadingEventHandler(FormEvents_Loading);
        }

        public void FormEvents_Loading(object sender, LoadingEventArgs e)
        {
            // 在此处编写代码。

         

            try
            {

                string userString = System.Environment.UserDomainName + "\\" + System.Environment.UserName;

                 SPSecurity.RunWithElevatedPrivileges(delegate()      //用此方法模拟管理员账户运行此事件处理程序
        {

 

                SPSite site = new SPSite("http://www.dosboy.net/");
                SPWeb myweb = site.RootWeb;
                myweb.AllowUnsafeUpdates = true;

                SPUser user = myweb.EnsureUser(userString);

                XPathNavigator myN = MainDataSource.CreateNavigator().SelectSingleNode("/my:myFields/my:field2", NamespaceManager);
                myN.SetValue(user.Name);

                SPGroupCollection groups = user.Groups;
                string ss = "";
                foreach (SPGroup group in groups)
                {
                    ss += group.ToString() + ";";

                }

                myN = MainDataSource.CreateNavigator().SelectSingleNode("/my:myFields/my:field2", NamespaceManager);
                myN.SetValue(ss);

             });

 

            }

            catch (Exception ex)
            {
               XPathNavigator  myN2 = MainDataSource.CreateNavigator().SelectSingleNode("/my:myFields/my:field2", NamespaceManager);
                myN2.SetValue(ex.Message );
 
            }

 

      

           

        }
    }
