158-convert-json-to-xml-and-convert-xml-document-to-text-in-c

In previous article we discussed how to convert XML data to json format. Converting in opposite direction is as just as simple. So to convert json to XML in C# let’s assume that we have data in json format are stored in text file. We need to open this file first.

string str_file_to_open;
str_file_to_open = openFileDialog2.FileName;
string str_tex_to_read;
StreamReader sr_StreamReader = new StreamReader(str_file_to_open);
str_tex_to_read = sr_StreamReader.ReadToEnd();
sr_StreamReader.Close();

When data are stored into string, we can de-serialize them in one line of code

XmlDocument doc = JsonConvert.DeserializeXmlNode(str_tex_to_read);

if, of course we have Newtonsoft.Json framework already installed and namespace

using Newtonsoft.Json;

included. Having data in XML format, we might want to convert XML document to text in C#. For that purpose, we can use StringWriter object and it’s GetStringBuilder() method.

string str_xml_to_text;
using (var stringWriter = new StringWriter())
{

using (var xmlTextWriter = XmlWriter.Create(stringWriter))
{

doc.WriteTo(xmlTextWriter);
xmlTextWriter.Flush();
str_xml_to_text = stringWriter.GetStringBuilder().ToString();

}

}

Whole code is:

if( openFileDialog2.ShowDialog() == DialogResult.OK)
{

string str_file_to_open;
str_file_to_open = openFileDialog2.FileName;
string str_tex_to_read;
StreamReader sr_StreamReader = new StreamReader(str_file_to_open);
str_tex_to_read = sr_StreamReader.ReadToEnd();
sr_StreamReader.Close();

XmlDocument doc = JsonConvert.DeserializeXmlNode(str_tex_to_read);
string str_xml_to_text;
using (var stringWriter = new StringWriter())
{

using (var xmlTextWriter = XmlWriter.Create(stringWriter))
{

doc.WriteTo(xmlTextWriter);
xmlTextWriter.Flush();
str_xml_to_text = stringWriter.GetStringBuilder().ToString();

}

}
textBox1.Text = str_xml_to_text;

}
