Create a logger in a static class.

Question

I have a logger.

private static ILogger _logger;

To create it, I have the method:

private static void CreatePayTelLogger(string clientConfigurationFilePath)
 {
    var composableLoggerFactory = new ComposableLoggerFactory();
    _logger = composableLoggerFactory.CreateComposableLogger(clientConfigurationFilePath);
 }

Now I have a static class in the production code, there is no constructor in this class. All the methods are directly called. How to create the logger in this class?

public static class ConfigHelpers
    {
        private static ILogger _logger;// I want to create and use it in this static class.
        public static int loadIntegerSetting(string settingNameInt, int defaultValueInt)
        {
            int outputVar;

            if (!int.TryParse(ConfigurationManager.AppSettings[settingNameInt] ?? defaultValueInt.ToString(), out outputVar))
            {
                if (outputVar == 0) outputVar = defaultValueInt;
                _logger.LogInfo("Defaulting " + settingNameInt + " App.config setting to '" +
                    defaultValueInt + "' due to config read error.");
            }
            else
                _logger.LogInfo(settingNameInt + " set to " + outputVar + ".");

            return outputVar;
        }

        public static bool loadBoolSetting(string settingNameBool, bool defaultValueBool)
        {
            bool outputVar;
            string parseText = ConfigurationManager.AppSettings[settingNameBool] ?? defaultValueBool.ToString(); // "false";

            if (parseText.Substring(0, 1).ToUpper() == "Y") parseText = "true"; 
            else if (parseText.Substring(0, 1).ToUpper() == "N") parseText = "false"; 

            if (!bool.TryParse(parseText, out outputVar))
            {
                if (!outputVar) outputVar = defaultValueBool;
                _logger.LogInfo("Defaulting " + settingNameBool + " App.config setting to '" +
                    defaultValueBool + "' due to config read error.");
            }
            else
                _logger.LogInfo(settingNameBool + " set to " + outputVar + ".");

            return outputVar;
        }

Thanks,

Static classes can have static constructors, if that helps. A static constructor would be automatically called before any static members are referenced, although you have no control as to exactly when it would get called.
