用代码实现Sharepoint2010的个人信息的照片上传(原创)

前言

Sharepoint2010的用户同步无法从AD中完全同步所有用户的照片信息到sharepoint2010的中来，经过查询微软资料需要打累计补丁http://support.microsoft.com/kb/2394320/zh-cn，累计补丁描述如下：

您尝试导入从 Active Directory thumbnailPhoto属性到 Microsoft SharePoint 服务器 2010 年的PictureURL属性在用户配置文件中的图片。设置导入PictureURL映射。然后，在 SharePoint 服务器执行完全同步。在这种情况下，图片不会添加到 SharePoint 服务器中的用户配置文件。

我在测试服务器上打了累计补丁，然后完全同步还是无法做到，再说累计补丁是微软没有经过测试的补丁，不敢在正式生产环境中打此类补丁。因此，需要考虑其他办法从AD或其他文件中同步用户的照片信息到sharepoint2010中来。

实现方法

实现思路

以管理员账号打开个人站点http://win-moss/my/,点【网站操作】-【查看所有网站内容】，如下图：

进入后找到【图片库】-【用户照片】如下图：

点击进入后可以看到MOSS个人站点下每个人的照片信息如下图：

可以看到每个用户都有3张照片，每张照片大小规格以及命名规则如下表格：

分为大中小三种图片，格式为JPG格式

明白这个后，其实我们就可以写代码操作图片库了，并把图片保存成3种大小规格，命名规则合符规定，最后更新UserProfile中的PictureUrl属性即可完成照片的上传。

实现方法

首先需要引用如下主要DLL，如下图：

Microsoft.Office.Server.dll

Microsoft.Office.Server.UserProfiles.dll

Microsoft.SharePoint.dll

microsoft.sharepoint.portal.dll

System.Drawing.dll

引用的命名空间如下：

using Microsoft.SharePoint;

using Microsoft.SharePoint.WebControls;

using System.IO;

using System.Drawing;

using Microsoft.Office.Server.UserProfiles;

using Microsoft.SharePoint.Portal.WebControls;

代码段：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Drawing;
using System.Reflection;
using Microsoft.SharePoint;
using Microsoft.SharePoint.WebControls;
using System.IO;
using Microsoft.Office.Server.UserProfiles;
using Microsoft.SharePoint.Portal.WebControls;
using System.Web;
using System.Threading;
using System.Globalization;
using System.Data;
using System.Collections;

测试结果：
在AD新建一个用户contoso\\test02,默认没有照片如下图：

在我的虚拟机C盘下建立一个文件夹（C:\photoFolder）并放上照片文件（Hydrangeas.jpg）如下图：

去【图片库】-【用户照片】也看不到test02的照片信息，如下图：


运行代码后：

去个人站点下的用户配置信息看照片如下图：



去【图片库】-【用户照片】可以看到如下图信息：
