[英]updated listitem attributes aren't commiting changes to sharepoint
i'm uploading a document to sharepoint.. however i would like to provide a custom name rather than it inherit the name of the file which im uploading.我正在将文档上传到 sharepoint .. 但是我想提供一个自定义名称,而不是继承我上传的文件的名称。
my code was based on this solution: http://www.codeproject.com/Articles/103503/How-to-upload-download-a-document-in-SharePoint-20.aspx我的代码基于此解决方案: http://www.codeproject.com/Articles/103503/How-to-upload-download-a-document-in-SharePoint-20.aspx
however this doesnt work.但是这不起作用。
Additionally, i would also like to provide a title of the file: so i wanted to update the title:此外,我还想提供文件的标题:所以我想更新标题:
uploadFile.ListItemAllFields.FieldValues["Title"] = "my custom title";
However, once the file has completed its upload..i login to sharepoint and notice the title hasnt been applied.但是,一旦文件完成上传..我登录到 sharepoint 并注意到标题尚未应用。
how can i intergrate uploading the file and applying a new name?我如何集成上传文件和应用新名称?
many thanks,非常感谢,
EDIT: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);
You are missing a call to clientContext.Load after you add the file to the Files collection.将文件添加到 Files 集合后,您缺少对 clientContext.Load 的调用。 See these blog posts for more information:

This code sample is from the first blog post linked above:此代码示例来自上面链接的第一篇博客文章:
public Boolean UploadDocument(String fileName, String filePath, List metaDataList)
{
SP.ClientContext ctx = new SP.ClientContext("http: //yoursharepointURL");
Web web = ctx.Web;
FileCreationInformation newFile = new FileCreationInformation();
newFile.Content = System.IO.File.ReadAllBytes(@"C: \TestFile.doc");
newFile.Url = " / " + fileName;
List docs = web.Lists.GetByTitle("Shared Documents");
Microsoft.SharePoint.Client.File uploadFile = docs.RootFolder.Files.Add(newFile);
context.Load(uploadFile);
context.ExecuteQuery();
SPClient.ListItem item = uploadFile.ListItemAllFields;
//Set the metadata
string docTitle = string.Empty;
item["Title"] = docTitle;
item.Update();
context.ExecuteQuery();
}
Are you calling Update after setting the field values?设置字段值后是否调用更新?
uploadFile.ListItemAllFields.Update();
instead of setting:而不是设置:
uploadFile.ListItemAllFields.FieldValues["Title"] = title;
uploadFile.ListItemAllFields.Update();
set it as follows:设置如下:
uploadFile.ListItemAllFields["Title"] = title;
uploadFile.ListItemAllFields.Update();
