第一种方法:
需要使用命名空间System.Runtime.Serialization.Json
下面有JsonReaderWriterFactory
XmlDictionaryReader reader = JsonReaderWriterFactory.CreateJsonReader(Encoding.UTF8.GetBytes(sJson), XmlDictionaryReaderQuotas.Max);
XmlDocument doc = new XmlDocument();
doc.Load(reader);
需要使用的命名空间 System.Web.Script.Serialization.JavaScriptSerializer
下面有JavaScriptSerializer
// json字符串转换为Xml对象
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<string, object> Dic = (Dictionary<string, object>)oSerializer.DeserializeObject(sJson);
XmlDocument doc = new XmlDocument();
XmlDeclaration xmlDec;
xmlDec = doc.CreateXmlDeclaration("1.0", "gb2312", "yes");
doc.InsertBefore(xmlDec, doc.DocumentElement);
XmlElement nRoot = doc.createElement_x("root");
doc.AppendChild(nRoot);
foreach (KeyValuePair<string, object> item in Dic)
{
XmlElement element = doc.createElement_x(item.Key);
KeyValue2Xml(element, item);
nRoot.AppendChild(element);
}
return doc;
}
private static void KeyValue2Xml(XmlElement node, KeyValuePair<string, object> Source)
{
object kValue = Source.Value;
if (kValue.GetType() == typeof(Dictionary<string, object>))
{
foreach (KeyValuePair<string, object> item in kValue as Dictionary<string, object>)
{
XmlElement element = node.OwnerDocument.createElement_x(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_x("Item");
KeyValuePair<string, object> item = new KeyValuePair<string, object>("Item", o[i]);
KeyValue2Xml(xitem, item);
node.AppendChild(xitem);
}
}
else
{
XmlText text = node.OwnerDocument.CreateTextNode(kValue.ToString());
node.AppendChild(text);
}
}
