我在SharePoint 2010中有一个列表,其中包含“title,count”字段。字段(count)可能会更改。
我想访问此属性的最新版本。通过这个article:但还没有接受答案。
File file;
FileVersionCollection versions;
ClientContext clientContext;
IEnumerable<Microsoft.SharePoint.Client.FileVersion> oldVersions;
clientContext = new ClientContext(siteUrl);
clientContext.Credentials = new NetworkCredential(user, password, shp.domainname);
Web web = clientContext.Web;
clientContext.Load(web);
clientContext.ExecuteQuery();
string path = web.ServerRelativeUrl + "/Lists/" + listname + "/" + id1 + "_.000"; // it represet list id 7
file = web.GetFileByServerRelativeUrl(path);
ListItem versionListItem = file.ListItemAllFields;
clientContext.Load(versionListItem);
clientContext.ExecuteQuery();
versions = file.Versions;
clientContext.Load(versions);
oldVersions = clientContext.LoadQuery(versions.Where(v => v != null));
clientContext.ExecuteQuery();
if (oldVersions != null)
{
foreach (Microsoft.SharePoint.Client.FileVersion _version in oldVersions)
{
DateTime date = new DateTime();
date = _version.Created.Date;
这里我可以访问属性,但这里不存在“count”。
我希望像SharePoint这样的最新版本存在差异
我有其他方法(找到它here),它返回给我最后一个属性值
ClientContext clientContext = new ClientContext("http://basesmc2008");
Web site = clientContext.Web;
clientContext.Load(site);
clientContext.ExecuteQuery();
File file = site.GetFileByServerRelativeUrl("/Shared Documents/test.tif");
clientContext.Load(file);
clientContext.ExecuteQuery();
ListItem currentItem = file.ListItemAllFields;
clientContext.Load(currentItem);
clientContext.ExecuteQuery();
FileVersionCollection versions = file.Versions;
IEnumerable<FileVersion> oldVersions = clientContext.LoadQuery(versions.Where(v => v.VersionLabel == "1.0"));
clientContext.ExecuteQuery();
if (oldVersions != null)
{
foreach (FileVersion oldFileVersion in oldVersions)
{
File oldFile = site.GetFileByServerRelativeUrl("/" + oldFileVersion.Url);
clientContext.Load(oldFile);
clientContext.ExecuteQuery();
ListItem oldItem = oldFile.ListItemAllFields;
clientContext.Load(oldItem);
clientContext.ExecuteQuery();
//error here
}
错误
发生错误。“,”ExceptionMessage“:”值不在其中 预期范围
有没有比此更短的解决方案来检索特定字段的所有最后值?
答案 0 :(得分:1)
可悲的是,CSOM无法提供实际版本数据。您可以通过从 / _ layouts / Versions.aspx?list = {[THE LIST ID]}&amp; ID = [THE ITEMID]&amp; IsDlg = 1 ;
中提取数据来获取数据我使用HTMLAgilityPack来解析我正在寻找的数据(特定字段的过去值)
HtmlDocument doc = new HtmlDocument();
doc.LoadHtml(DownloadedPageContent);
HtmlNodeCollection n = doc.DocumentNode.SelectNodes("//tr[@id='vv" + VersionId + FieldName +"']/td");
String value = n[1].InnerText.Trim();
