更新的列表项属性不会改变commiting到SharePoint [英] updated listitem attributes aren't commiting changes to sharepoint

问题描述

即时上传文件到SharePoint。不过我想提供一个自定义的名称，而不是它继承了文件，IM上传的名称。

我的代码是基于该解决方案：的 http://www.codeproject.com/Articles/103503/How-to-upload-download-a-document-in-SharePoint-20.aspx

然而，这并不工作。

此外，我也想提供该文件的标题：
，所以我想更新标题

  uploadFile.ListItemAllFields.FieldValues [标题] =我的自定义标题; 
  

然而，一旦该文件已完成了upload..i登录到SharePoint并注意标题已处理不当应用。

我怎么能G642.44各级上传文件并应用新的名字吗？

千恩万谢，

编辑：

 （VAR clientContext = GetNewContext（））
 {
 VAR uploadLocation =的String.Format（{0} {1} / {2}，主页，Helpers.ListNames.RequestedDocuments，Path.GetFileName（文件））; 
 
 //获取文档列表
 VAR documentslist = clientContext.Web.Lists.GetByTitle（Helpers.ListNames.RequestedDocuments）; 
 
变种fileCreationInformation =新FileCreationInformation 
 {
含量= System.IO.File.ReadAllBytes（文件），//分配给内容的byte []即documentStream 
覆盖= TRUE，//允许owerwrite文件
 URL = uploadLocation // URL上传，
 
}的; 
 
 VAR uploadFile = documentslist.RootFolder.Files.Add（fileCreationInformation）; 
 
 uploadFile.ListItemAllFields.FieldValues [标题] =称号; 
 
 uploadFile.ListItemAllFields.Update（）; 
 
 clientContext.ExecuteQuery（）; 
} 
 site.SubmitChanges（ConflictMode.FailOnFirstConflict，真）; 
  

解决方案

您缺少一个电话后，你clientContext.Load将文件添加到文件的集合。看到这些博客文章以了解更多信息：

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.

my code was based on this solution: http://www.codeproject.com/Articles/103503/How-to-upload-download-a-document-in-SharePoint-20.aspx

however this doesnt work.

Additionally, i would also like to provide a title of the file: so i wanted to update the title:

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.

how can i intergrate uploading the file and applying a new name?

many thanks,

EDIT:

        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);

解决方案

You are missing a call to clientContext.Load after you add the file to the Files collection. See these blog posts for more information:
