如何讀取XML文件內容

下面是通過讀取XML文件中的內容並顯示在textbox的例子：

using System;
using System.Data;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.XML;
using System.XML.XPath;

public partial class _Default : System.Web.UI.Page
{
    public string[] x = new string[4];
    protected void Page_Load(object sender, EventArgs e)
    {

        XmlDocument xmlDoc = new XMLDocument();
        xmlDoc.Load(Server.MapPath("table.xml"));//你的XML文件
        XmlNodeList xmlList = XMLDoc.SelectSingleNode("MapSheet").ChildNodes;
        foreach (XmlNode xmlNo in XMLList)
        {
            //XmlNodeList xe = (XmlNodeList)XMLNo;
            XmlElement xe = (XmlElement)XMLNo;
            {
                if (xe.Name == "TableName")
                {
                    y[0] = xe.InnerText;
                }

                if (xe.Name == "DataSource")
                {
                    y[1] = xe.InnerText;
                }

                if (xe.Name == "UserName")
                {
                    y[2] = xe.InnerText;
                }

                if (xe.Name == "PassWord")
                {
                    y[3] = xe.InnerText;
                }
            }
        }
        TextBox1.Text=y[0];
        TextBox2.Text = y[1];
        TextBox3.Text = y[2];
        TextBox4.Text = y[3];
    }

}該程序已經過測試，沒有問題。
