检索排序列表SharePoint 2010 C＃的第一个列表项

Question

I just started SharePoint webpart programming today. I have list called "pagesList" and I want to order its list items using the field "sortField" in descending order. Then I want to get the first item in the list. here is what I tried so far but I don't know how to get the first item in the sorted list to assign it.

if (pagesList != null)
{
    SPQuery q = new SPQuery();
    q.Query = "<OrderBy><FieldRef Name='sortField' Ascending='False' /></OrderBy>";
    SPListItemCollection listItemCollection = pagesList.GetItems(q);
    CurrentIssueLinkButton.PostBackUrl = /* the first item of the sorted listitems goes here*/;
 }  

How can I get the first list item?

将SPQuery对象的RowLimit设置为1，以确保最多返回一项。
