finding the Last Monday Date

[litton1]

What is the best way to find the date of the previous Monday?

At the moment I am using a DateTime type and subtracting 1 out of the constructor until I get to a Monday. Must be better way…? Thx T

Sorry, what I did was, I used a date time picker just for this, I made it visible = false so it wasn’t actually viewable. Then I wrote this function

		private void SetDTPToLastMonday()
		{
			string aDay = dtpMonday.Value.DayOfWeek.ToString();

			//create a time span object of one day
			System.TimeSpan ad = new TimeSpan(1,0,0,0);
			if(aDay != "Monday")
			{
				do 
				{
					dtpMonday.Value = dtpMonday.Value.Subtract(ad);
					aDay = dtpMonday.Value.DayOfWeek.ToString();
                }while (aDay != "Monday");
			}
			
		}

a nice recursive algorithm would do just as well

somtehing like

 private void button1_Click(object sender, EventArgs e)
        {
            textBox1.Text = searchlastmonday(1).ToString("dd/MM/yyyy");   

        }

        private DateTime searchlastmonday(int tosubstract)
        {
            if ((System.DateTime.Today.AddDays(-tosubstract)).DayOfWeek != System.DayOfWeek.Monday)
            {
                searchlastmonday(tosubstract -= 1);
            }
            return System.DateTime.Today.AddDays(-tosubstract);
        }
