導入XML類的屬性

我有XML格式如下：導入XML類的屬性

使用多個SessionTuning，現在我想在我的字符串數組導入此XML。

我的現有代碼：

public static clsSessionTuningData[] GetSessionTuningFromXMLFile(string FileName) 
     { 
      try 
      { 

       StreamReader objReader = new StreamReader(FileName); 
       string strData = objReader.ReadToEnd(); 
       objReader.Close(); 

       int nStart = 0, nEnd = 0; 
       nStart = strData.IndexOf("<SessionTuningData>"); 
       nEnd = strData.IndexOf("</SessionTuningData>"); 
       if (nStart > 0 && nEnd > 0) 
       { 

        nStart = nStart + "<SessionTuningData>".Length; 
        nEnd = nEnd + "</SessionTuningData>".Length; 
        strData = strData.Substring(nStart + 1, nEnd - nStart - 1); 
        string[] strSessionTuning = strData.Split('\r', '\n'); 
        clsSessionTuningData[] objSessionTuning = new clsSessionTuningData[1]; 
        clsDataType.XMLType objXML = new clsDataType.XMLType(); 

        int j = 0; 
        for (int i = 0; i < strSessionTuning.GetLength(0); i++) 
        { 
         objXML = clsCommonFunc.GetXML(strSessionTuning[i]); 

         if (objXML != null) 
         {

       return null; 
      } 
      catch (Exception ex) 
      { 
       clsErrorTrace.CreateLog("SessionTuning", ex); 
       return null; 
      } 
     }

但這個作品，如果我知道最後一個屬性是Tuning_ID。

有沒有一種簡單的方法去與此..？

哦，我的上帝！你有沒有聽說過有關'Serialization'？ – 2013-02-27 13:27:47

是的，我聽說過這個，但對此不知道。 – 2013-02-27 13:28:58

@VishalSuthar我建議你從學習xml序列化開始。它簡化了很多事情：http：// tech。pro/tutorial/798/csharp-tutorial-xml-serialization – Botz3000 2013-02-27 13:33:34

，你可以：

1）您的XML加載到一個XMLDocument，再通過其屬性（主要是ChildNodes）瀏覽文檔; 2）將XML加載到XMLDocument中，然後使用XPath查詢文檔，通過CreateNavigator創建導航器。

3）用XmlReader解析文檔。

4）創建一組與Xml架構密切相關的類，並使用XmlDeserializer將文件映射到一組對象（這很好，但設置起來很棘手，因爲XmlDeserializer可能有點頑固配置）。

如果我需要所有的數據，我會選擇（4），可能重新設計我的XML /模型類，使轉換更容易。

如果我需要一些值，我可能會去（2），因爲它只需要很少的代碼。查看（2）here的一些示例。

當然有更簡單的方法來做到這一點。其中一個名爲Serialization，您可以將整個類轉換爲某種類型的流，即XML和字節。你使用XmlSerializer這個類。下面是一個簡單的例子：

假設你有，你要存儲在一個類和XML文件：

[Serializable] // you should mark the class as serializable 
public class MyData 
{ 
    public int Value { get; set; } 
    public string Name { get; set; } 
    public string[] SubItems { get; set; } 
}

這個代碼把它轉換成XML文件：

MyData data = new MyData(); 
data.Name = "TestName"; 
data.Value = 100; 
data.SubItems = new string[] {"Item1", "Item2", "Item3"}; 
XmlSerializer ser = new XmlSerializer(typeof(MyData)); 
using (FileStream file = new FileStream(fileName, FileMode.Create, FileAccess.Write)) 
{ 
    ser.Serialize(file, data); 
}

這裏生成的文件：

<?xml version="1.0"?> 
<MyData xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> 
    <Value>100</Value> 
    <Name>TestName</Name> 
    <SubItems> 
    <string>Item1</string> 
    <string>Item2</string> 
    <string>Item3</string> 
    </SubItems> 
</MyData>

讀取該文件，您可以使用Deserialize方法：

using (FileStream file = new FileStream(fileName, FileMode.Open, FileAccess.Read)) 
{ 
    ser.Deserialize(file, data); 
}

另一種選擇是使用專門的類別中的一個.NET框架讀取XML文件：

XDocument doc = XDocument.Load(fileName); 
List<clsSessionTuningData> objSessionTuning = new List<clsSessionTuningData>() 
foreach (var session in doc.Descendants("SessionTuningData")) 
{ 
    XElement elem; 
    clsSessionTuningData data = new clsSessionTuningData(); 
    elem = session.Element("Revision2"); 
    if (elem != null) 
     data.bRevision2 = elem.Value; 

    // and so on... 
}
