Question

I want to write a simple stopwatch program, I can make it work with the following code

    public Form1()
    {
        InitializeComponent();
    }
    Syst         


        

Answer 1

• additional SetOffset() method
• additional initialization with offset;
• overrides all of needed methods
• have the same class name, so no need to change your project code

.

using System;

public class Stopwatch : System.Diagnostics.Stopwatch
{
    TimeSpan _offset = new TimeSpan();

    public Stopwatch()
    {
    }

    public Stopwatch(TimeSpan offset)
    {
        _offset = offset;
    }

    public void SetOffset(TimeSpan offsetElapsedTimeSpan)
    {
        _offset = offsetElapsedTimeSpan;
    }

    public TimeSpan Elapsed
    {
        get{ return base.Elapsed + _offset; }
        set{ _offset = value; }
    }

    public long ElapsedMilliseconds
    {
        get { return base.ElapsedMilliseconds + _offset.Milliseconds; }
    }

    public long ElapsedTicks
    {
        get { return base.ElapsedTicks + _offset.Ticks; }
    }
}
