How Can I Efficiently Create JSON Strings in C#?

Create JSON string in C#

When building an HTTP response, you often need to send data in different formats, including JSON. This question explores how to create JSON strings in C# using string builders and external libraries such as Newtonsoft.Json.

Answer:

The JSON creation process can be simplified using the Newtonsoft.Json library:

Product product = new Product();
product.Name = "Apple";
product.Expiry = new DateTime(2008, 12, 28);
product.Price = 3.99M;
product.Sizes = new string[] { "Small", "Medium", "Large" };

string json = JsonConvert.SerializeObject(product);

Newtonsoft.Json provides a comprehensive set of methods for serializing and deserializing various data types to and from JSON. As shown in the above example, a custom object can be easily converted into a JSON string by using its "SerializeObject" method.

In addition, please refer to the following documentation:
