C# Self Initated class – how to use in project

I have created a class and self initialized it in the file – is this the best way to use it? I have another Constant class that I can use but I am unable to use this for some reason in my project, do they need to be consts?

File: test.cs

using System;
using System.Collections.Generic;
using System.Text;

namespace DH.Models
{
    public class test
{
        public string testSourceCollection { get; set; }
        public string testSourceKey { get; set; }
        public string testSourceDatabase { get; set; }
        public string testSourceCluster { get; set; }
        public string testSourceTimestamp { get; set; }

        public test[] testDetails = {
                    new test{
                        testSourceCollection = "SourceCollection",
                        testSourceDatabase = "SourceDatabase ",
                        testSourceKey = "SourceKey ",
                        testSourceTimestamp = "SourceTimestamp "
                    },
                    new ProviderRecon
                    {
                        testSourceCollection = "testSourceCollection2",
                        testSourceDatabase = "testSourceDatabase2",
                        testSourceKey = "testSourceKey2",
                        testSourceTimestamp = "testSourceTimestam2",
                        testSourceCluster = "testSourceCluster2"
                    }
                    };
        }
    
}

I would like to use in my Worker.cs file as such

public class Worker : BackgroundService
        {
           var test = test.testDetails;
           Console.WriteLine("2nd test: " + test.testSourceCluster )
           //Prints "2nd test: testSourceCluster2"
        }

>Solution :

You probably want testDetails to be static. You can’t access (non-static) members using a type. Change public test[] testDetails = ... to public static test[] testDetails =...

However, you have a lot of non-standard namings there, which make this code confusing to read. The class test should be called Test instead. The line var test = test.testDetails; is hard to read otherwise (and probably won’t compile). Same is true for your Worker class. That piece of code won’t compile.
