我需要一种方法来使用.NET

更改xml文件中的数据（编辑/删除）

Answer 1

如果您不想使用XmlDataSource控件，还可以使用LINQ to XML从文件中创建数据源对象：

XDocument doc = XDocument.Load("somefile.xml");

var results = from answer in doc.Descendants("Answer")
              select new
              {
                  Question = answer.Attribute("questionId").Value,
                  Answer = answer.Value
              };

GridView1.DataSource = results;
GridView1.DataBind();

Answer 2

System.Web.UI.WebControls.XmlDataSource类将返回给定XML文件的ASP.NET DataSource。给定的链接包括示例代码和演练。

请注意，如果必须使用XML属性作为键，则XPath expressin将包含Answer[@MRN]之类的内容。

如何将XML文件转换为DataSource？
