上传文件到 Sharepoint 的文档库中和下载 Sharepoint 的文档库的文件到客户端

文件操作应用场景：

如果你的.NET项目是运行在SharePoint服务器上的，你可以直接使用SharePoint服务器端对象模型，用SPFileCollection.Add方法

http://msdn.microsoft.com/zh-cn/library/ms454491%28office.12%29.aspx

如果不在同一台机器上，并且你的SharePoint是2010，你可以使用.NET客户端对象模型，用FileCollection.Add方法

http://msdn.microsoft.com/zh-cn/library/microsoft.sharepoint.client.filecollection.add(en-us).aspx

如果是SharePoint 2007，你可以用SharePoint Web Service里面的copy.asmx

Function: 支持上传文件到Sharepoint的文档库中；下载Sharepoint的文档库的文件到客户端

Support three ways as following:

1)通过调用SharePoint的Copy.asmx服务实现；只适用于SharePoint站点

IFileOperation fileOperation = new SPServiceOperation();

bool isSuccess = fileOperation.UploadFileToSPSite(domain, userAccount, pwd, documentLibraryUrl, localFilePath, ref statusInfo);

bool isSuccess = fileOperation.DownloadFileFromSPSite(domain, userAccount, pwd, documentUrl, downloadToLocalFilePath, ref statusInfo);

2)通过WebClient实现；适用于普通站点

IFileOperation fileOperation = new WebClientOperation();

3)通过WebRequest实现；适用于普通站点

IFileOperation fileOperation = new WebRequestOperation();

关键代码：

IFileOperation.cs

     }

 }

结果：

PS：如用第一种方式，就得在Visual Studio中添加Web Service，服务来源，例如：
