Answer 1

Hello,

Welcome to Microsoft Q&A!

1. Read the json content from file .
2. Deserialize the content into object .
3. Add a new property named image in model and assign the value to it .
4. Serialize the object into json string .
5. Write the string into file .

Model

   public class RootObject  
       {  
           public string name { get; set; }  
           public string id { get; set; }  
           public string image { get; set; }  // add this property  
       }  

Original json data

   {"name":"cole" , "id" : "123"}  

Handling

   var file = Path.Combine(System.Environment.GetFolderPath(System.Environment.SpecialFolder.Personal), "test.json");  
     
               if (File.Exists(file))  
               {  
                   string text = File.ReadAllText(file);  
     
                   RootObject obj = JsonConvert.DeserializeObject<RootObject>(text);  
     
                   obj.image = "https://us.v-cdn.net/5019960/uploads/userpics/468/p1NMCBY2PV254.jpeg";  
     
                   string json = JsonConvert.SerializeObject(obj);  
     
                   File.WriteAllText(file, text);  
               }  

(Embedding resource does not support writing operation , so we can't use it . )
