Convert object to json string with property name as string value of class

Question

I have the following class structure:

public class JsonModel
{
    public string PropertyName { get; set; }
    public string PropertyValue { get; set; }
}

And I have an instance of this class as follows:

var entry = new JsonModel { PropertyName = "foo", PropertyValue = "bar" };

I want to convert this to json, but I want it to come out like this:

{
    "foo": "bar"
}

How cant his be done?

Answer 1

assuming that your class has only 2 properties ( name and value) you can use this

var entry = new JsonModel { PropertyName = "foo", PropertyValue = "bar" };
    
var json=   GetJson(entry);
 
public string GetJson(object obj)
{  
    var prop= obj.GetType().GetProperties();
   
   var prop1=prop[0].GetValue(obj, null).ToString();
   var prop2= prop[1].GetValue(obj, null).ToString();

    return "{\n\"" + $"{prop1}\": \"{prop2}" + "\"\n}";
}

json

{
 "foo": "bar"
}

if you wnat to use a serializer, it can be done like this

public string GetJsonFromParsing(object obj)
{
    var json=JsonConvert.SerializeObject(obj);
    var properties=JObject.Parse(json).Properties().ToArray();

    var prop1 = properties[0].Value;
    var prop2 = properties[1].Value;

    return "{\n\"" + $"{prop1}\": \"{prop2}" + "\"\n}";
}
