Create a new Console Application Install Newtonsoft.Json: Right-click on your project in Solution Explorer, select "Manage NuGet Packages," search for "Newtonsoft.Json," and install it. Write Code to Read JSON: Replace the contents of your Program.cs file with the following code: using System; using Newtonsoft.Json; using System.IO; class Program { static void Main() { try { // Replace "sample.json" with the path to your JSON file string filePath = "sample.json"; // Read the JSON file content string jsonContent = File.ReadAllText(filePath); // Deserialize JSON to an object MyObject myObject = JsonConvert.DeserializeObject (jsonContent); // Display the deserialized object Console.WriteLine($"Name: {myObject.Name}"); Console.WriteLine($"Age: {myObject.Age}"); } catch (Exception ex) { Console.WriteLine($"An error occurred: {ex.Message}"); } } } class MyObject { public string Name { get; set; } public int Age { get; set; } } Hope this will help.

Hello, You need to install " Newtonsoft.Json" package NuGet in your project then need to deserialize your JSON content to object. YourClassModel objClassModel = JsonConvert.DeserializeObject (jsonContent);

To create a simple application that can read JSON files using the Newtonsoft.Net library, you will need to follow a few steps. First, make sure you have the Newtonsoft.Net library installed in your project. You can do this by using the NuGet package manager in Visual Studio or by manually adding the library to your project. Once you have the library installed, you can start by creating a new console application in Visual Studio. In the Program.cs file, add the necessary using statement to import the Newtonsoft.Net library: using Newtonsoft.Json; Next, you can create a method to read the JSON file. Here's an example of how you can do this: static void ReadJsonFile(string filePath) { // Read the JSON file contents string json = File.ReadAllText(filePath); // Deserialize the JSON into an object var jsonObject = JsonConvert.DeserializeObject(json); // Access the properties of the object // ... // Process the JSON data // ... } In the Main method, you can call the ReadJsonFile method and pass the path to the JSON file as an argument: static void Main(string[] args) { string filePath = "path/to/your/json/file.json"; ReadJsonFile(filePath); } Remember to replace "path/to/your/json/file.json" with the actual path to your JSON file. By following these steps, you should be able to create a simple application that can read JSON files using the Newtonsoft.Net library. Feel free to customize the code according to your specific requirements and data structure.

Here is a simple console application in C# that uses the Newtonsoft.Json library to read JSON files: using System; using System.IO; using Newtonsoft.Json; class Program { static void Main(string[] args) { string filePath = "path_to_your_json_file.json"; // Replace with your JSON file path try { // Read the file as a string string json = File.ReadAllText(filePath); // Deserialize the JSON string into a dynamic object dynamic obj = JsonConvert.DeserializeObject(json); // Print the JSON object Console.WriteLine(obj); } catch (Exception ex) { Console.WriteLine($"An error occurred: {ex.Message}"); } } } This program reads a JSON file from the specified path, deserializes it into a dynamic object using JsonConvert.DeserializeObject , and then prints the object to the console. Please replace "path_to_your_json_file.json" with the actual path to your JSON file. Remember to install the Newtonsoft.Json package in your project before running this code. You can do this via the NuGet Package Manager in Visual Studio, or by running the following command in the Package Manager Console: Install-Package Newtonsoft.Json Please note that this is a basic example. Depending on the structure of your JSON file, you might need to adjust the code to properly read and handle the data. If your JSON corresponds to a specific class, you can replace dynamic with that class for stronger typing. If you’re reading a large JSON file, consider using JsonTextReader for better performance.
