JSON goto XML

The first method:

You need to use a namespace System.Runtime.Serialization.Json

There are jsonreaderwriterfactory below.

XmlDictionaryReader reader = Jsonreaderwriterfactory.createjsonreader (Encoding.UTF8.GetBytes (Sjson), Xmldictionaryreaderquotas.max);
XmlDocument doc = new XmlDocument ();
Doc. Load (reader);

The namespace System.Web.Script.Serialization you need to use. JavaScriptSerializer

Below are JavaScriptSerializer

JSON string conversion to XML object
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);
}
}
