c# - 无法使用客户端对象模型从 SharePoint 库中检索文件信息

Question

我正在尝试使用客户端对象模型从 SharePoint 2010 库中的文件中读取一些属性。这是示例

using SP = Microsoft.SharePoint.Client;

SP.ClientContext clientContext = new SP.ClientContext( "http://path/to/the/site" );
clientContext.Load( clientContext.Web );
clientContext.ExecuteQuery();

SP.File spFile = clientContext.Web.GetFileByServerRelativeUrl("/TestLibrary/sample.pdf");
clientContext.Load(spFile);
clientContext.ExecuteQuery(); //here we'll catch exception

但我收到异常。

A first chance exception of type 'Microsoft.SharePoint.Client.ServerException' occurred in Microsoft.SharePoint.Client.Runtime.dll

附加信息:值不在预期范围内。

我做错了什么？

Answer 1

错误 Value does not fall in the expected range. 发生自 Web.GetFileByServerRelativeUrl method接受以下格式的 serverRelativeUrl 参数:

/Site_Name/SubSite_Name/Library_Name/File_Name

例子:

using (var ctx = new ClientContext("https://intranet.contoso.com/news"))
{
    var file = ctx.Web.GetFileByServerRelativeUrl("/news/Documents/SharePoint User Guide.docx");
    ctx.Load(file);
    ctx.ExecuteQuery();  
}
