How in C# create JSON object without class [dynamically]

C# create a JSON object dynamically: Here in this article, we are going to see how we can create JSON objects on the fly. Yes, we can create a JSON object dynamically in C# without creating a class object.  In C# application using newtonsoft library, makes working with JSON very easy.

First, we have to add Newtonsoft from the NuGet package manager into our project. Then add namespaces Newtonsoft.Json.Linq as written below:

 using Newtonsoft.Json.Linq;

C# code to generate a dynamic JSON string

We have created a method CreateJson() which returns us JSON string.

public string CreateJson() 
{
	dynamic obj = new JObject();
	obj.Name = "Satinder Singh";
	obj.Location = "Mumbai";
	obj.blog = "Codepedia.info";
	
	var jsonString = Newtonsoft.Json.JsonConvert.SerializeObject(obj);
	return jsonString;
} 

Here is the preceding code with JsonConvert.SerializeObject we serialize our object and get a JSON string.

Output:

Conclusion: By using dynamic datatype and Newtonsoft library we can easily able to create dynamic JSON in C# without any class.
