ASP.Net 向xml文件中添加数据(insert操作)
废话不说,代码如下:XML文件请见ASP.Net中实现XMl的标识列(ID列)或自增长列
private bool Insert_XML()
{
try
{
XmlDocument doc = new XmlDocument();
string filename = Server.MapPath(".//XML//User.xml");
doc.Load(filename);
XmlNode root = doc.DocumentElement;
XmlNode user = doc.CreateElement("user");
DataSet ds = new DataSet();
ds.ReadXml(filename);
int userid = ds.Tables[0].Rows.Count+1;
//写入userid
XmlElement elem6 = doc.CreateElement("userid");
elem6.InnerText = userid.ToString();
user.AppendChild(elem6);
//写入用户名
XmlElement elem1 = doc.CreateElement("username");
elem1.InnerText = this.Txt_username.Text.Trim();
user.AppendChild(elem1);
//写入密码
XmlElement elem2 = doc.CreateElement("userpass");
elem2.InnerText = this.Txt_pasw.Text.Trim();
user.AppendChild(elem2);
//写入Email
XmlElement elem3 = doc.CreateElement("usermail");
elem3.InnerText = this.Txt_usermail.Text.Trim();
user.AppendChild(elem3);

elem5.InnerText = this.Txt_msn.Text.Trim();
user.AppendChild(elem5);
//写入日期
XmlElement elem8 = doc.CreateElement("ndate");
elem8.InnerText = DateTime.Now.ToString();
user.AppendChild(elem8);
root.AppendChild(user);
doc.Save(filename);
this.Lab_flag.Text = "注册成功!";
this.HyperLink1.Visible=true;

return true;
}
catch(Exception ex)
