.NET和讀取xml文件

Question

我想閱讀以下xml和填充知識標籤在一個組合框中，項目名稱標籤在文本框中，其餘的在組合框以及。任何代碼示例都會非常有幫助。

<?xml version="1.0" encoding="UTF-8"?> 
<swobs> 
    <item> 
      <knowledge>1</knowledge> 
      <knowledge>2</knowledge> 
      <knowledge>3</knowledge> 
      <knowledge>4</knowledge> 
      <itemname>INS Gator Operator</itemname> 
      <knowhow>1</knowhow> 
      <knowhow>2</knowhow> 
      <knowhow>3</knowhow> 
      <knowhow>4</knowhow> 
      <supervisor>1</supervisor>  
      <supervisor>2</supervisor>  
      <supervisor>3</supervisor>  
      <supervisor>4</supervisor> 
     </item>    
</swobs> 

如果我試試這個：

public void LoadXML() { 
    string myXMLfile = Server.MapPath("~/swobs.xml"); 
    DataSet dssowbs = new DataSet(); 
    try 
    { 
      dssowbs.ReadXml(myXMLfile); 
      DropDownList1.DataSource = dssowbs; 
      DropDownList1.DataValueField = "knowledge"; 
      DropDownList1.DataBind(); 
    } 
    catch (Exception ex) 
    { 
      Response.Write(ex.ToString()); 
    } 
} 

它拋出一個錯誤。

學會愛LINQ ......這是多麼簡單：

private void LoadData() 
     { 
      var allData = XElement.Load("yourdatafile.xml"); 
      this.comboKnowledge.ItemsSource = allData.Descendants("knowledge").Select(x => x.Value); 
      this.textItemName.Text = allData.Descendants("itemname").Select(x => x.Value).SingleOrDefault(); 
      this.comboKnowHow.ItemsSource = allData.Descendants("knowhow").Select(x => x.Value); 
      this.comboSupervisor.ItemsSource = allData.Descendants("supervisor").Select(x => x.Value); 
     }
