Your Debug.CallObjectEvent()<\/code> method explicitly instantiates a Call<\/code> object and calls the overridden method in that class:<\/p>\n

public static class Debug\n{\n    internal static void CallObjectEvent(string log)\n    {\n        new Call().CallEvent(new Log(log, Timer.GetTime()));\n    }\n}\n<\/code><\/pre>\n
The CallEvent()<\/code> method in the Call<\/code> class simply calls base.Event()<\/code>, which resolves to IDebug.Event()<\/code>. The Program.Event()<\/code> override is never invoked because Program<\/code> is not in the class hierarchy at the point of the call.<\/p>\n
When you override a method or property, the override applies only to the class where it is defined (and all of its child classes, of course). Since Program<\/code> isn’t a parent class of Call<\/code> there’s no reason why its overrides would ever be referenced.<\/p>\n
From what you’ve written it looks like you’re trying to set up a system for handling different log outputs depending on the program’s requirements. You need a way to register the appropriate log writer for your program. Something like:<\/p>\n
public interface ILogWriter\n{\n    void Event(Log item);\n}\n\nprivate class DefaultLogWriter : ILogWriter\n{\n    public void Event(Log item)\n    {\n        Console.WriteLine($\"[test] {item.Time} {item.Message}\");\n    }\n}\n\ninternal static class Debug\n{\n    private static ILogWriter _writer = null;\n\n    public static ILogWriter Writer \n    { \n        get\n        {\n            if (_writer == null)\n                _writer = new DefaultLogWriter();\n            return _writer;\n        }\n        set => _writer = value;\n    }\n\n    internal static void CallObjectEvent(string log)\n    {\n        Writer.Event(new Log(log, Timer.GetTime()));\n    }\n}\n\nclass Program\n{\n    private class MyLogWriter : ILogWriter\n    {\n        public void Event(Log item)\n        {\n            Console.WriteLine($\"[MyLogWriter] {item.Time} {item.Message}\");\n        }\n    }\n\n    static void Main()\n    {\n        Debug.Writer = new MyLogWriter();\n\n        Debug.CallObjectEvent(\"Test message.\");\n    }       \n}\n<\/code><\/pre>\n<\/p><\/div>\n
