從XML文件讀取C＃

我正在嘗試讀取XML文檔。現在，如果我從「/ word/link1」中讀取信息，則可以調用信息，但只要我深入瞭解「buttons/word/link1」，就根本無法讀取InnerText。從XML文件讀取C＃

public void rxml() 
    { 
     XmlTextReader read = new XmlTextReader("C:\\myXmFile.xml"); 
     XmlDocument doc = new XmlDocument(); 
     doc.Load(read); 
     switch (P) 
     { 
      case "word": 
       label11.Text = "Microsoft Word Documents"; 

       l1 = doc.SelectSingleNode("buttons/word/link1").InnerText = "hello"; 
       p1 = doc.SelectSingleNode("buttons/word/path1").InnerText; 
       l2 = doc.SelectSingleNode("buttons/word/link2").InnerText = linkLabel2.Text; 
       p2 = doc.SelectSingleNode("buttons/word/path2").InnerText;

@Marshal我認爲這可能是一個好主意，發佈一個簡短的XML文件與此代碼失敗。 – spender 2012-02-20 11:27:54

爲了使訪問數據更容易，你應該accesing數據創建類。通過將問題分解到不同的級別，它可以讓整體更容易理解，調試並保持最新狀態。我已經開始使用this file of extensions創建了一個示例。

要使用下面你會得到的wordlink1有：

ButtonsXml buttons = new ButtonsXml("C:\\myXmFile.xml"); 
string link1 = buttons["word"][1].Link;

下面的代碼：

public class ButtonsXml 
{ 
    XElement self; 
    Dictionary<string, DataCollection> list = new Dictionary<string, DataCollection>(); 

    public ButtonsXml(string file) 
    { 
     self = XElement.Load(file); 
    } 

    public DataCollection this[string name] 
    { 
     get 
     { 
      if (list.ContainsKey(name)) 
       return list[name]; 
      DataCollection c = new DataCollection(self.GetElement(name)); 
      list.Add(name, c); 
      return c; 
     } 
    } 

    public void Save(string file) 
    { 
     self.Save(file); 
    } 
} 

public class DataCollection 
{ 
    XElement self; 
    public Dictionary<int, Element> list = new Dictionary<int,Element>(); 

    public DataCollection(XElement self) 
    { 
     this.self = self; 
    } 

    public Element this[int index] 
    { 
     get 
     { 
      if (list.ContainsKey(index)) 
       return list[index]; 
      Element e = new Element(self, index); 
      list.Add(index, e); 
      return e; 
     } 
    } 
} 

public class Element 
{ 
    XElement parent; 
    int index; 

    public Element(XElement parent, int index) 
    { 
     this.parent = parent; 
     this.index = index; 
    } 

    public string Path 
    { 
     get { return parent.GetString("path" + index.ToString(), string.Empty); } 
     set { parent.Set("path" + index.ToString(), value, XElementConversions.ELEMENT); } 
    } 

    public string Link 
    { 
     get { return parent.GetString("link" + index.ToString(), string.Empty); } 
     set { parent.Set("link" + index.ToString(), value, XElementConversions.ELEMENT); } 
    } 
}

如果你想要將其值設置爲路徑或鏈路，我已經添加的setter：它們將以相同的方式設置。那麼需要調用buttons.Save(file)來保存對文件的更改。

buttons["word"][1].Link = "new value";
