Question

I have the following code

internal abstract class Base
{
    public DateTime Time;
    public string Message;
    public string Log;
    public abstract void Invoke(string message);
}

internal class SubA : Base
{
    public override void Invoke(string message)
    {
        Time = DateTime.Now;
        // Do A
    }
}

internal class SubB : Base
{
    public override void Invoke(string message)
    {
        Time = DateTime.Now;
        // Do B
    }
}

I have these SubA and SubB classes which inherits from Base class, you can see that i have a code that repeating it self which is setting the Time, is there a way to move the setting of the time to the base class?

There a many possible solutions.

This depends on when you want to have this propertie set.

If you want it immediately you can do this in the constructor of your Base class.

internal abstract class Base
{
    public DateTime Time;
    public string Message;
    public string Log;
    public abstract void Invoke(string message);

    public Base()
    {
        Time = DateTime.Now;
    }
}

internal class SubA : Base
{
    public override void Invoke(string message)
    {
        // Do A
    }
}

internal class SubB : Base
{
    public override void Invoke(string message)
    {
        // Do B
    }
}
