1、XML与String的相互转换

[1] XML 转为 String

//载入Xml文件XmlDocument xdoc = new XmlDocument();xdoc.Load("xml文件");string xmlStr = xdoc.InnerXml;

 

[2] String 转为 XML

//载入Xml字符串XmlDocument xdoc = new XmlDocument();xdoc.LoadXml("xml字符串");//保存为Xml文件xdoc.Save("xml文件");

 

2、XML 与 Json 的相互转换

[1] XML 转换为 Json

using System.Xml;  using Newtonsoft.Json;  string xml = "
     
      
       Test class
      
      
       100
      
      
       200
      
     ";  XmlDocument doc = new XmlDocument();  doc.LoadXml(xml);  string json = Newtonsoft.Json.JsonConvert.SerializeXmlNode(doc);

 

[2] Json 转换为 XML 

方法一：

string json = Newtonsoft.Json.JsonConvert.SerializeXmlNode(xml);  XmlDocument xmlDoc = Newtonsoft.Json.JsonConvert.DeserializeXmlNode(json);xmlDoc.Save("F:/example.xml");

 

方法二：

　　　　using System.Xml; 　　　　using System.Runtime.Serialization.Json; 　　　　using System.Web.Script.Serialization; 　　　　/// 
         /// json字符串转换为Xml对象         /// XmlDictionaryReader命名空间为using System.Runtime.Serialization.Json;       /// JavaScriptSerializer需添加System.Web.Extensions.dll引用 　　　　/// JavaScriptSerializer命名空间为System.Web.Script.Serialization;        /// 
         ///          /// 
              public static XmlDocument Json2Xml(string sJson)       {           //XmlDictionaryReader reader = JsonReaderWriterFactory.CreateJsonReader(Encoding.UTF8.GetBytes(sJson), XmlDictionaryReaderQuotas.Max);             //XmlDocument doc = new XmlDocument();             //doc.Load(reader);             JavaScriptSerializer oSerializer = new JavaScriptSerializer();           Dictionary
     
       Dic = (Dictionary
      
       )oSerializer.DeserializeObject(sJson);           XmlDocument doc = new XmlDocument();           XmlDeclaration xmlDec = doc.CreateXmlDeclaration("1.0", "UTF-8", "yes");           doc.InsertBefore(xmlDec, doc.DocumentElement);           XmlElement nRoot = doc.CreateElement("root");           doc.AppendChild(nRoot);           foreach (KeyValuePair
       
         item in Dic)           {               XmlElement element = doc.CreateElement(item.Key);               KeyValue2Xml(element, item);               nRoot.AppendChild(element);           }           return doc;       }       private static void KeyValue2Xml(XmlElement node, KeyValuePair
        
          Source)       {           object kValue = Source.Value;           if (kValue.GetType() == typeof(Dictionary
         
          ))           {               foreach (KeyValuePair
          
            item in kValue as Dictionary
           
            ) { XmlElement element = node.OwnerDocument.CreateElement(item.Key); KeyValue2Xml(element, item); node.AppendChild(element); } } else if (kValue.GetType() == typeof(object[])) { object[] o = kValue as object[]; for (int i = 0; i < o.Length; i++) { XmlElement xitem = node.OwnerDocument.CreateElement("Item"); KeyValuePair
            
              item = new KeyValuePair
             
              ("Item", o[i]); KeyValue2Xml(xitem, item); node.AppendChild(xitem); } } else { XmlText text = node.OwnerDocument.CreateTextNode(kValue.ToString()); node.AppendChild(text); } }
