JSON to C# Objects Conversion: A Simplified Guide
JSON (JavaScript Object Notation) is a convenient data format for exchanging information between systems. In C#, converting JSON text into objects allows you to easily access and manipulate data. Here's a step-by-step guide to achieve this:
Step 1: Install Newtonsoft.Json via NuGet
To deserialize JSON into C# objects, you need the Newtonsoft.Json library. Install it through the NuGet Package Manager in your project.
Step 2: Use Json.NET's JsonConvert Class
Once installed, deserialize the JSON text using the JsonConvert class:
// Replace "jsonString" with your JSON content Rootobject r = Newtonsoft.Json.JsonConvert.DeserializeObject<Rootobject>(jsonString);
Step 3: Define the Root Object Class
In Visual Studio, paste the JSON text and select "Edit" > "Paste Special" > "Paste JSON as Classes." This creates a C# class that matches the JSON structure. Alternatively, you can manually create this class based on the JSON response.
public class Rootobject
{
public string err_code { get; set; }
public string org { get; set; }
public string des { get; set; }
public string flight_date { get; set; }
public List<Schedule> schedule { get; set; }
}
Step 4: Access Data from Objects
Once the class is created, you can access its properties to manipulate the data in the JSON response. For instance, you can access the err_code property to check the success or failure status of the response.
Example Usage:
// Get the first schedule item Schedule scheduleItem = r.schedule[0]; // Access properties from the schedule item string flightNumber = scheduleItem.flight_number; string departureDate = scheduleItem.departure_date; string departureTime = scheduleItem.departure_time;
By following these steps, you can effortlessly convert JSON text into C# objects, making it easy to work with structured data in your applications.

C Polymorphism : is function overloading a kind of polymorphism?
Jun 20, 2025 am 12:05 AM
Yes, function overloading is a polymorphic form in C, specifically compile-time polymorphism. 1. Function overload allows multiple functions with the same name but different parameter lists. 2. The compiler decides which function to call at compile time based on the provided parameters. 3. Unlike runtime polymorphism, function overloading has no extra overhead at runtime, and is simple to implement but less flexible.
What Are the Different Kinds of Polymorphism in C ? Explained
Jun 20, 2025 am 12:08 AM
C has two main polymorphic types: compile-time polymorphism and run-time polymorphism. 1. Compilation-time polymorphism is implemented through function overloading and templates, providing high efficiency but may lead to code bloating. 2. Runtime polymorphism is implemented through virtual functions and inheritance, providing flexibility but performance overhead.
C : Is Polymorphism really useful?
Jun 20, 2025 am 12:01 AM
Yes, polymorphisms in C are very useful. 1) It provides flexibility to allow easy addition of new types; 2) promotes code reuse and reduces duplication; 3) simplifies maintenance, making the code easier to expand and adapt to changes. Despite performance and memory management challenges, its advantages are particularly significant in complex systems.

Polymorphism in C : A Comprehensive Guide with Examples
Jun 21, 2025 am 12:11 AM
Polymorphisms in C are divided into runtime polymorphisms and compile-time polymorphisms. 1. Runtime polymorphism is implemented through virtual functions, allowing the correct method to be called dynamically at runtime. 2. Compilation-time polymorphism is implemented through function overloading and templates, providing higher performance and flexibility.
C tutorial for people who know Python
Jul 01, 2025 am 01:11 AM
People who study Python transfer to C The most direct confusion is: Why can't you write like Python? Because C, although the syntax is more complex, provides underlying control capabilities and performance advantages. 1. In terms of syntax structure, C uses curly braces {} instead of indentation to organize code blocks, and variable types must be explicitly declared; 2. In terms of type system and memory management, C does not have an automatic garbage collection mechanism, and needs to manually manage memory and pay attention to releasing resources. RAII technology can assist resource management; 3. In functions and class definitions, C needs to explicitly access modifiers, constructors and destructors, and supports advanced functions such as operator overloading; 4. In terms of standard libraries, STL provides powerful containers and algorithms, but needs to adapt to generic programming ideas; 5
