Question
Below is the code:
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());
Irrespective of the changes done, it always shows 0.
Solution
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());
Even though I don't prefer creating token by yourself, this seems to be the only way which works as per my googling so far.
