使用XmlDocument将dropdownlist中显示的书名的其它信息读入到相应的文本框中

protected void Button1_Click(object sender, EventArgs e)

{

XmlNode node= xdoc.DocumentElement.SelectSingleNode("book[name='"+this.DropDownList1.Text+"']");

#region 方法一

foreach (XmlNode item in node.ChildNodes)

{

if(item.LocalName=="author")

{

this.TextBox1.Text = item.InnerText;

}

if (item.LocalName == "publisher")

{

this.TextBox2.Text = item.InnerText;

}

if (item.LocalName == "date")

{

this.TextBox3.Text = item.InnerText;

}

if (item.LocalName == "isbn")

{

this.TextBox4.Text = item.InnerText;

}

if (item.LocalName == "price")

{

this.TextBox5.Text = item.InnerText;

}

}

#endregion

#region 方法二

TextBox1.Text = node.SelectSingleNode("author").InnerText;

TextBox2.Text = node.SelectSingleNode("publisher").InnerText;

TextBox3.Text = node.SelectSingleNode("date").InnerText;

TextBox4.Text = node.SelectSingleNode("isbn").InnerText;

TextBox5.Text = node.SelectSingleNode("price").InnerText;

#endregion
