Question

我有这个xml文件：

<?xml version='1.0'?>
<!-- This file represents a fragment of a book store inventory database -->
<root>
  <radio>
    <title>The Autobiography of Benjamin Franklin</title>
    <url>https://www.google.com</url>

  </radio>
  <radio>
    <title>The Autobiography of n Franklin</title>
    <url>https://www.facebook.com</url>

  </radio>
  <radio>
    <title>The Autobiography of Benjaminin</title>
    <url>https://www.yahoo.com</url>

  </radio>

</root>

我通过以下代码在组合框中显示了标题标记：

Dim doc As New XmlDocument()
    doc.Load("books.xml")
Dim elemList As XmlNodeList = doc.GetElementsByTagName("title")
    Dim i As Integer
    For i = 0 To elemList.Count - 1
        ComboBox1.Items.Add(elemList(i).InnerXml)
    Next i

所以我想当用户点击组合框中的标题时，网页浏览器导航到与xml文件中的标题链接的网址。

C＃

将xml加载到匿名类型列表。将它绑定到组合框。

var xmlDoc = XElement.Load("books.xml");

var nodes = xmlDoc.Elements("radio")
    .Select(elem => new
    {
        Title = elem.Element("title").Value,
        Url = elem.Element("url").Value
    })
    .ToList();

comboBox.DisplayMember = "Title";
comboBox.ValueMember = "Url";
comboBox.DataSource = nodes;

导航至网址。

private void ComboBox_SelectedIndexChanged(object sender, EventArgs e)
{
    webBrowser.Navigate(comboBox.SelectedValue.ToString());
}

将数据从xml文件检索到WebBrowser
