Answer 1

我能想到将XML绑定到gridview的最简单方法是将xml加载到DataSet，然后将DataSet绑定到gridview：

StringReader sr= new StringReader(xml); 
DataSet ds = new DataSet();
ds.ReadXml(sr);

Gridview.DataSource=ds.Tables[1];
Gridview.DataBind();

执行ds.Tables[0]的原因是您的示例包含2组Answers，当您使用XML加载DataSet时，第一个DataTable将包含与您在答案上的答案集一样多的行XML，而第二个表将包含所有答案集中的所有行。

LinqPad显示的方式如下：

StringReader sr= new StringReader(xml); 
 DataSet ds = new DataSet();
