Answer 1

You can use two global DateTime variable and in click twice button diff to variable;

   private DateTime btn1Click ;
   private DateTime btn2click;


        private void btn1_Click(object sender, EventArgs e)
        {
            btn1Click = DateTime.Now;
        }

        private void btn2_Click(object sender, EventArgs e)
        {
            btn2click = DateTime.Now;
        }

and use this code for diff time:

 TimeSpan timespan = btn2click - btn1Click;

In same button :

  private DateTime btnClick1 ;
        private DateTime btnClick2;

  private void btn_Click(object sender, EventArgs e)
        {
            if (btnClick1==null)
            {
                btnClick1 = DateTime.Now;
            }
            else
            {
                btnClick2 = DateTime.Now;
            }
        }
