读取XML并绑定至RadioButtonList

读取XML的文档，可以使用System.Data.DataSet类别中的ReadXml()方法。如下面的xml文档，放在站点的根目录之下：

YearOfBirth.xml

<?xml version="1.0" encoding="utf-8" ?>
<YearOfBirths>
  <YearOfBirth>
    <ID>1</ID>
    <Name>鼠</Name>
  </YearOfBirth>
  <YearOfBirth>
    <ID>2</ID>
    <Name>牛</Name>
  </YearOfBirth>
  <YearOfBirth>
    <ID>3</ID>
    <Name>虎</Name>
  </YearOfBirth>
  <YearOfBirth>
    <ID>4</ID>
    <Name>兔</Name>
  </YearOfBirth>
  <YearOfBirth>
    <ID>5</ID>
    <Name>龙</Name>
  </YearOfBirth>
  <YearOfBirth>
    <ID>6</ID>
    <Name>蛇</Name>
  </YearOfBirth>
  <YearOfBirth>
    <ID>7</ID>
    <Name>马</Name>
  </YearOfBirth>
  <YearOfBirth>
    <ID>8</ID>
    <Name>羊</Name>
  </YearOfBirth>
  <YearOfBirth>
    <ID>9</ID>
    <Name>猴</Name>
  </YearOfBirth>
  <YearOfBirth>
    <ID>10</ID>
    <Name>鸡</Name>
  </YearOfBirth>
  <YearOfBirth>
    <ID>11</ID>
    <Name>狗</Name>
  </YearOfBirth>
  <YearOfBirth>
    <ID>12</ID>
    <Name>猪</Name>
  </YearOfBirth>
</YearOfBirths>

使用一个属性来获取这个文档：

 private string XmlFile
    {
        get
        {
            return Server.MapPath("~/YearOfBirth.xml");
        }
    }

在aspx网页上拉一个RadioButtonList控件，用来显示XML的数据。

<asp:RadioButtonList ID="RadioButtonListYearOfBirth" runat="server" RepeatColumns="6" RepeatDirection="Horizontal"></asp:RadioButtonList>

接下来，用DataSet去读取刚才写好的获取XML文件的属性。

View Code

using System;
using System.Collections.Generic;
using System.Data;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

public partial class Default3 : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
            Data_Binding();

    }

    private void Data_Binding()
    {
        using (DataSet ds = new DataSet())
        {
            ds.ReadXml(XmlFile);
            this.RadioButtonListYearOfBirth.DataSource = ds;
            this.RadioButtonListYearOfBirth.DataTextField = "Name";
            this.RadioButtonListYearOfBirth.DataValueField = "ID";
            this.RadioButtonListYearOfBirth.DataBind();
        }
    }
}
