如何读取XML文件内容

下面是通过读取xml文件中的内容并显示在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];
}

}该程序已经过测试，没有问题。
