How to hold particular url key from .json file based on the value given in the function parameter

Question

API Testing using RestSharp

I have added config.json file and maintaining all the URL in the file. Example

{
   "Url1": "http://localhost:45677",
   "Url2": "http://localhost:45897"
}

I would like to fetch particular URL from the config.json based on the given parameter added in class2

public class class2
{
    public void Url1_Request()
    {
        var client = class1.RestClient("Url1");
    }
    public void Url2_Request()
    {
        var client = class1.RestClient("Url2");
    }
}


public class class1
{
    public static RestClient RestClient(string url)
    {

        var client = new RestClient(url);
        return client;
    }
}

Answer 1

you can use this code

using Newtonsoft.Json;
.....

public static RestClient restClient()
{
    string json = string.Empty;
    using (StreamReader r = new StreamReader(@"C:\...\config.json"))
        json = r.ReadToEnd();
        
    var jsonObject=JObject.Parse(json);
    
    var url=GetUrl(jsonObject,"Url1");
   return new RestClient(url);
}
    
public string GetUrl(JObject jsonObject, string url)
{
    return  (string) jsonObject[url];
}

url

http://localhost:45677
