how to create json file in c#

JavaScript
        //Create my object
        var my_jsondata = new
        {
            Host = @"sftp.myhost.gr",
            UserName = "my_username",
            Password = "my_password",
            SourceDir = "/export/zip/mypath/",
            FileName = "my_file.zip"
        };

        //Tranform it to Json object
        string json_data = JsonConvert.SerializeObject(my_jsondata);

        //Print the Json object
        Console.WriteLine(json_data);

        //Parse the json object
        JObject json_object = JObject.Parse(json_data);

        //Print the parsed Json object
        Console.WriteLine((string)json_object["Host"]);
        Console.WriteLine((string)json_object["UserName"]);
        Console.WriteLine((string)json_object["Password"]);
        Console.WriteLine((string)json_object["SourceDir"]);
        Console.WriteLine((string)json_object["FileName"]);
//open file stream
using (StreamWriter file = File.CreateText(@"D:\path.txt"))
{
     JsonSerializer serializer = new JsonSerializer();
     //serialize object directly into file stream
     serializer.Serialize(file, _data);
}//For any of the JSON parse, use the website 
//http://json2csharp.com/ 
//(easiest way) to convert your JSON into 
//C# class to deserialize your JSON into C# object.

public class FormatClass
{
	public string JsonName { get; set; }      
	public string JsonPass { get; set; }      
}
//Then use the JavaScriptSerializer (from System.Web.Script.Serialization),
// in case you don't want any third party DLL like newtonsoft.
public void Read()
{
  	using (StreamReader Filejosn = new StreamReader("Path.json"))
	{
   		JavaScriptSerializer jss = new JavaScriptSerializer();
   		var Items = jss.Deserialize<FormatClass>(Filejosn.ReadToEnd());
  		// Add Code here :)
	}
}
