我有一个控制台应用程序,试图将文档上载到共享点文档库列表中。
我能够成功完成此操作,同时还能在使用C#上传文件时填充自定义Column(列名称为“类别”)值之一。
我尝试使用相同的过程填充另一个自定义列(列名称为:“相关资产”)值,但是我收到错误消息,指出所提供的列名称不存在,但是当我在实际的共享点门户中看到时存在。
因此无法解决此问题。甚至我尝试了如下所示的几种方法,但在该列不存在或它已被删除或无法识别的情况下,我得到了相同的错误消息。
请找到显示列列表的SharePoint屏幕快照:
请找到我到目前为止所拥有的将文档上载到SharePoint门户的代码。
public static async Task<string> UploadReleaseNoteDocumentintoSpPortal(string releasenotefilepath, string releasenotefilename, string clientid, string clientsecret)
{
string status = string.Empty;
try
{
Console.WriteLine("Trying to Upload Release note file into Share Point Portal...");
string siteUrl = "<<Sp site URL>>";
Console.WriteLine("Connecting to Share Point Portal...");
var ClientContext = new OfficeDevPnP.Core.AuthenticationManager().GetAppOnlyAuthenticatedContext(siteUrl, clientid, clientsecret);
ClientContext.Load(ClientContext.Web, p => p.Title);
await ClientContext.ExecuteQueryAsync();
Console.WriteLine(ClientContext.Web.Title);
var web = ClientContext.Web;
Console.WriteLine("Connected successfully to Share Point Portal...");
List DocumentsList = web.Lists.GetByTitle("Accelerators Documents");
ClientContext.Load(DocumentsList.RootFolder);
await ClientContext.ExecuteQueryAsync();
Console.WriteLine("Reading and loading the list named : Accelerators Documents from SP");
Console.WriteLine("Converting the release note document into byte array");
byte[] bytes = System.IO.File.ReadAllBytes(releasenotefilepath);
MemoryStream stream = new MemoryStream(bytes);
Console.WriteLine("Storing the release note Data into File Create information object of SharePoint");
FileCreationInformation FileCreateInfo = new FileCreationInformation();
FileCreateInfo.Content = bytes;
FileCreateInfo.ContentStream = stream;
FileCreateInfo.Overwrite = true;
FileCreateInfo.Url = DocumentsList.RootFolder.ServerRelativeUrl + @"\" + releasenotefilename;
Console.WriteLine("Adding file to SharePoint");
var ReleaseNoteFiledata = DocumentsList.RootFolder.Files.Add(FileCreateInfo);
ReleaseNoteFiledata.Update();
ReleaseNoteFiledata.ListItemAllFields["Category"] = "Release Notes";
//ReleaseNoteFiledata.ListItemAllFields["Related Assets"] = "<<Desired Value>>";
//IN Above commented line i get the error stating Microsoft.SharePoint.Client.ServerException:
//'Column 'Related Assets' does not exist. It may have been deleted by another user.
//But in actual site if we see it exists as you can see in above screenshot
ReleaseNoteFiledata.ListItemAllFields.Update();
ClientContext.Load(ReleaseNoteFiledata);
await ClientContext.ExecuteQueryAsync();
Console.WriteLine("Adding file to SharePoint Completed Successfully...");
return status = "Successful";
}
catch (Exception ex)
{
Console.WriteLine("Exception occured while trying to upload Release note file into CoP Portal :" + ex.Message);
return status = "Error/Exception";
}
}
请尝试在向SharePoint中存在的另一个自定义列添加值时发现错误消息: Microsoft.SharePoint.Client.ServerException:'列'相关资产'不存在。它可能已被其他用户删除。
即使我使用ReleaseNoteFiledata.SetFileProperties()
并将值作为包含列名及其值的字典键值对传递,那么对于第二个自定义列,我也会遇到相同的错误。如果我只保留类别自定义列,那么它可以完美工作而没有任何问题,如您在上面的屏幕快照中所见。
如果我选择记录并在SharePoint中查看详细信息或属性,则“相关资产”列符号类似于以下屏幕截图:
请让我知道支持文档是否还可以,或者我的问题还是无法理解的,以便我可以重新构图或提供更多屏幕截图。
请帮助我解决以上问题,或如何使该列在代码中可识别,可读或可识别。
预先感谢
致谢
