How do I use my custom logging configuration?

using System;
using System.IO;
using NLog;
using NLog.Config;
using NLog.Targets;
using Newtonsoft.Json.Linq;

namespace LoggingExample
{
    class Logging
    {

        static void Logging()
        {

                var config = new LoggingConfiguration();

                var consoleTarget = new ColoredConsoleTarget();
                config.AddTarget("console", consoleTarget);
                var fileTarget = new FileTarget();
                config.AddTarget("file", fileTarget);

                consoleTarget.Layout = "${message}";

                fileTarget.FileName = "C:/log.txt";
                fileTarget.Layout = "${message}";


                consoleTarget.UseDefaultRowHighlightingRules = true;

                string json = File.ReadAllText("config.json");
                JObject jo = JObject.Parse(json);
                string debugLevel = (string) jo.SelectToken("Logging_Properties.LogLevel");

                LogLevel level = TestDebugLevel(debugLevel) ? LogLevel.FromString(debugLevel) : LogLevel.Info;

                LoggingRule rule1 = new LoggingRule("Console", LogLevel.Debug, consoleTarget);
                LoggingRule rule2 = new LoggingRule("File", level, fileTarget);

                config.LoggingRules.Add(rule1);
                config.LoggingRules.Add(rule2);

                LogManager.Configuration = config;



        }

        static bool TestDebugLevel(string level)
        {
            switch (level.ToLower())
            {
                case "info":
                    return true;
                case "debug":
                    return true;
                case "warn":
                    return true;
                case "error":
                    return true;
                case "fatal":
                    return true;
                default:
                    return false;

            }
        }
    }

My application must contain a programatically configured logger, the only issue is that I have no idea how to use it. I think everything is written correctly but I have no idea how to actually call the the logger within the application. I know I have to use Logmanager.GetLogger() with the logger I want to use, either the console or file logger but when I try to nothing gets logged.

You aren't logging anything, but only configuring NLog.

You need to log to the logger, in this case, after calling Log() (this could be in another class)

var appConsoleLogger = LogManager.GetLogger("ConsoleLogger");
appConsoleLogger.Info("info log to console");

var appFileLogger = LogManager.GetLogger("FileLogger");
appFileLogger.Info("info log to file");

PS: The name of your method is a bit confusing, I think it should "SetupLogging" instead of "Log"

I think you're missing one LogManager.ReconfigExistingLoggers()
