如何從SharePoint 2010客戶端對象模型中獲取更改？

Question

下面是代碼：

 ClientContext context = new ClientContext("http://SPSite"); 
     context.Credentials = new NetworkCredential("user", "pwd", "domain"); 
     ChangeQuery cq = new ChangeQuery(true, true);     
     ChangeCollection col = list.GetChanges(cq);    
     context.Load(col); 
     context.ExecuteQuery(); 
     MessageBox.Show(col.Count.ToString()); 

所做的變化不論，它總是顯示爲0。

Answer 1

ClientContext context = new ClientContext("http://SPSite"); 
context.Credentials = new NetworkCredential("user", "pwd", "domain"); 
ChangeQuery cq = new ChangeQuery(true, true); 
cq.ChangeTokenStart = new ChangeToken(); 
cq.ChangeTokenStart.StringValue = "1;3;" + list.Id.ToString() + ";" + DateTime.UtcNow.AddHours(-1).Ticks.ToString() + ";-1";     
ChangeCollection col = list.GetChanges(cq);    
context.Load(col); 
context.ExecuteQuery(); 
MessageBox.Show(col.Count.ToString()); 

即使我不喜歡創造自己的道理，這似乎是唯一的根據我的谷歌搜索目前的工作方式。
