How to read data from a file which contains data in JSON syntax and store requird keys and values as a variable

Question

I have to say this is not a perfect world stackoverflow problem where I'm stuck with a code level problem But I want to know how I can full fill the following requirement. Any Suggestion/advice would be great

I have a main folder , which contains many sub-folders . Each of these subfolders are expected to have a FieServer.config file which has data in JSON format as shown in the code below.

{
  "name": "Max",
  "age": "six",
  "gender": "Male",
  "country": "india",
}

I want to know how I can Read from the file and store the 2 keys "Name" and "Country" along with its respective values as variables to be used in my C# project.

Any suggestions for the above requirement

You can first read the FieServer.config file as string and then use the Newtonsoft.Json library to read/deserialize the json string. newtonsoft.com/json/help/html/… newtonsoft.com/json/help/html/JObjectProperties.htm — Jaydeep Jadav

Your best option will be to first prepare an object to be used for the data. i.e.

public class FileConfigData 
{ 
  public string Name { get; set; }
  public string Country {get; set; }
}

Then just use any json serializer to transform the JSON to an object. Here's an example with json.Net lib: var configData = JsonConvert.DeserializeObject(File.ReadAllText(CONFIG_FILE_PATH)));

To get all the files into a array you can use:

string[] fileConfigs = Directory.GetFiles("path/to/dir", "FieServer.config", SearchOption.AllDirectories);

and then iterate the array like this:

List<FileConfigData> configList = new List<FileConfigData>();
foreach (var file in fileConfigs){
   var configData = JsonConvert.DeserializeObject<FileConfigData>(File.ReadAllText(CONFIG_FILE_PATH)));
configList.Add(configData);
 }
