You can use [ScriptIgnore] attribute from System.Web.Script.Serialization on every property that you want to exclude from the object when serializing or deserializing:

  using System.Web.Script.Serialization;

  public class Product{
        public int ProductId { get; set; }
        public string ProductName { get; set; }

        [ScriptIgnore]
        public DataTable dt = new DataTable();
        [ScriptIgnore]
        public Category Category = new Category();
    }

JSON Object to properties, Lets say you have the following Json string yourJsonString = "{\"FIRST_NAME\":\" Foo\",\"LAST_NAME\":\"Bar\"}";. You could model this Json as: public class� The JSON property naming policy: Applies to serialization and deserialization. Is overridden by [JsonPropertyName] attributes. This is why the JSON property name Wind in the example is not upper case. Camel case dictionary keys. If a property of an object to be serialized is of type Dictionary<string,TValue>, the string keys can be converted to

In same class, create two functions returning boolean like this:

 public bool ShouldSerializedt()
 {
      return false;
 }

 public bool ShouldSerializeCategory()
 {
      return false;
 }

Function returns boolean. Its name is ShouldSerialize<<PropertyName>> and the return type of boolean controls serialization behavior

Working with JSON in MVC, JSON Java Script Object Notation is a very familiar and commonly used concept. JSON object and we explicitly specify few properties of the model and miss out on others, MVC framework Using JSON, AJAX, jQuery With ASP.NET MVC 4 Application - Part 2 � Convert JSON Data Into Data Grid Columns. A point to note here is that, when we assign/cast (actually) a model into JSON object and we explicitly specify few properties of the model and miss out on others, MVC framework is clever enough to first convert the model with each property into JSON and then assign default values to those properties which we have missed.

Best to use C# serialization mechanism. You may need separate class for the purpose of this "limited" serialization (in case you want these properties serialized in other scenarios) but that should do it. Take a look here: How to exclude property from Json Serialization

JsonResult Type in MVC, It helps to send the content in JavaScript Object Notation (JSON) format.

How to serialize and deserialize JSON using C#, NET objects (deserialize); Deserialization behavior; Serialize to formatted JSON; Customize JSON names and values; Exclude properties from serialization� JSON represents objects in structured text format and data stored in key-value pairs. Many third-party controls like Kendo UI grid supply data from client size to server-side in JSON string format so it is necessary to cast our JSON string to the appropriate object to access data.There are many ways for working with JSON in C# code.

How to write custom converters for JSON serialization, This article shows how to create custom converters for the JSON Deserialize inferred types to object properties. The factory pattern creates a class that determines, at run time, which specific type is required and dynamically creates C# Copy. using System; using System.Globalization; using System. [HttpPost] public ActionResult JsonCreateNew(Person person) { // the default ASP.NET MVC model binder isn't able to bind to this // in fact, the routing module does not even route the request to this // action, so this action never gets fired.

Serialization Attributes, JsonPropertyAttribute - Placed on fields and properties to control how they should be serialized as a property in a JSON object. JsonConverterAttribute - Placed on either classes or fields and properties to specify which JsonConverter should� The above code i am using in my controller , now when i deploy the view page its opening a download dialog in my browser , when open the file it gives me json object as i needed format.

  • One possible way is to return anonymous object like return Json(new { ProductId = dto.ProductId, ... });
  • Possible duplicate of Only serialize some specific properties of a class?
  • Can you tell me about Controller?
  • The controller is fine and does not need any changes.
  • Try [ScriptIgnore] from System.Web.Script.Serialization instead of [JsonIgnore] and let me know it's working.
  • use [ScriptIgnore] instead of [JsonIgnore] It's working. Thank you.
  • Glad it helped. And since you are using JavaScriptSerializer , [JsonIgnore] wouldn't work for you.
  • I don't understand, I am beginner.
  • In the same Product class where you are defining properties like ProductId , ProductName etc. define the functions I mentioned. Check the name of both functions. Name starts with "ShouldSerialize" and end with "dt" or "Category" which are names of properties which shouldn't be serialized. If such function returns false, then corresponding property won't get serialized.
  • I already try [JsonIgnore] It's not work. but use [ScriptIgnore] It's work. Answer from above.
