I have simple C# object instantiated like:
User theUser = new User("John", "Doe");
Now I need to load it to my Node.js file like:
var theUser = {name:"John", lastName:"Doe"};
How can I do that? Do I have to save/write the output on a separate JSON file?
If you intend to use JSON as bridge from C# to Nodejs, use JavaScriptSerializer class to convert your C# class as JSON data.
https://msdn.microsoft.com/en-us/library/system.web.script.serialization.javascriptserializer.aspx
C#
// your data class
public class YourClassName
{
...
}
// Javascript serialization
using System.IO;
using System.Web.Script.Serialization;
String json = new JavaScriptSerializer().Serialize(YourClassName);
File.WriteAllText("json_file_path", json);
Node.js
// Async mode
var jsondata = require('fs').readFile('json_file_path', 'utf8', function (err, data) {
if (err) throw err; // throw error if not found or invalid
var obj = JSON.parse(jsondata);
});
// Sync mode
var jsondata = JSON.parse(require('fs').readFileSync('json_file_path', 'utf8'));
Node.js reference: How to parse JSON using Node.js?
Hopefully this is useful, CMIIW.
Why not just use Newtonsoft.Json - add a reference to this within your project.
To convert the object from a known type to json string;
string output = JsonConvert.SerializeObject(theUser);
To convert the object to a dynamic type;
dynamic json = JToken.Parse(theUser); - to dynamic
MSDN Link for extra help, if needed.
