How to convert large JSON file to XML?

Question

C++ / C#

Hello!
In general, the current implementation is as follows:

string file = File.ReadAllText("file.json");
XmlDocument doc = JsonConvert.DeserializeXmlNode("{\"dialog\":" + file + "}", "root");
file = doc.InnerXml.Replace("<root>", "<root><dialogs>");
doc = null;
file = file.Replace("</root>", "</dialogs></root>");
...
File.WriteAllText("output.xml", file);

instead of an ellipsis there are a few more Replaces. The JSON file weighs 400-700 MB and with this implementation OutOfMemoryException crashes at the first Replace.
How to be? What solutions can be given to this situation?
