Question

例如，我有一个带有BookDetails的xml文件，我将它显示在GridView表单上。现在我想为GridView提供添加，编辑，删除选项。当我们从SQL数据源使用DataBinding时，我知道如何为gridview添加，编辑和删除选项，但在这里我们应该将数据存储到现有的xml文件中。

包含数据的Xml文件：

 <books>
    <book>
        <title>CLR via C#</title>
        <isbn>0735667454</isbn>
        <author>Jeffrey Richter</author>
    </book>
    <book>
        <title>Pro C# 5.0 and the .NET 4.5 Framework</title>
        <isbn>1430242337</isbn>
        <author>Andrew Troelsen</author>
    </book>
    <book>
        <title>Building Windows 8 Apps with C# and XAML</title>
        <isbn>0321822161</isbn>
        <author>Jeremy Likness</author>
    </book>
</books>

ASP.NET代码

<html xmlns="http://www.w3.org/1999/xhtml">
    <head>
        <title>Book Store</title>
    </head>
    <body>
        <form id="form1" runat="server">
            <div>
                <asp:GridView ID="gvBooks" runat="server">
                </asp:GridView>
            </div>
        </form>
    </body>
</html>

C＃代码

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

public partial class Default : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        bindXml();
    }
    private void bindXml()
    {
        //Create a DataSet
        DataSet ds = new DataSet();
        //Load the XML data into the DataSet
        ds.ReadXml(Server.MapPath("books.xml"));

        //Bind the DataSet to the GridView control
        gvBooks.DataSource = ds;
        gvBooks.DataBind();
    }
}

将数据添加到按钮上的Xml文件中单击C＃
