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();

这样做的原因ds.Tables[0]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XML上的答案集一样多的行,而第二个表将包含来自所有XML的所有行.一套答案.

LinqPad显示它的方式如下:

更新:

string xml=@"<?xml version=""1.0""?>
