我正在将文档上传到sharepoint ..但是我想提供一个自定义名称而不是它继承我上传的文件的名称.
我的代码基于这个解决方案:http://www.codeproject.com/Articles/103503/How-to-upload-download-a-document-in-SharePoint-20.aspx 但这不起作用. 另外,我还想提供文件的标题: uploadFile.ListItemAllFields.FieldValues["Title"] = "my custom title"; 但是,一旦文件完成其upload..i登录到sharepoint并注意标题尚未应用. 我如何整合上传文件并应用新名称? 非常感谢, 编辑: using (var clientContext = GetNewContext()) { var uploadLocation = string.Format("{0}{1}/{2}",SiteUrl,Helpers.ListNames.RequestedDocuments,Path.GetFileName(document)); //Get Document List var documentslist = clientContext.Web.Lists.GetByTitle(Helpers.ListNames.RequestedDocuments); var fileCreationInformation = new FileCreationInformation { Content = System.IO.File.ReadAllBytes(document),//Assign to content byte[] i.e. documentStream Overwrite = true,//Allow owerwrite of document Url = uploadLocation //Upload URL,}; var uploadFile = documentslist.RootFolder.Files.Add(fileCreationInformation); uploadFile.ListItemAllFields.FieldValues["Title"] = title; uploadFile.ListItemAllFields.Update(); clientContext.ExecuteQuery(); } site.SubmitChanges(ConflictMode.FailOnFirstConflict,true); 解决方法
将文件添加到Files集合后,您将缺少对clientContext.Load的调用.有关更多信息,请参阅这些博文:
