C#

protected void Timer1_Tick(object sender, System.EventArgs e)
	{
		DateTime mydate2 = DateTime.Now;
		DateTime mydate3 = default(DateTime);

		try {
            mydate3 = (mydate - mydate2).ToString();
			this.Label5.Text = "Time Left: " + mydate3.ToShortTimeString();
		} catch (Exception ex) {
			this.Label5.Text = "Error Setting up the Timer. Contact Admin";
		}

        
		if (mydate3.ToShortTimeString() == "00:00:00") {
			int marks = 0;
			Session["Answered"]=dt ;

			foreach (object x_loopVariable in dt.Rows) {
				 x=x_loopVariable ;
				if (x("Selected") + 1 == x("correct")) {
					marks += 1;

				}
			}

I got errors in this code:

C#

mydate3 = (mydate - mydate2).ToString();

C#

foreach (object x_loopVariable in dt.Rows) {
				 x=x_loopVariable ;
				if (x("Selected") + 1 == x("correct")) {
					marks += 1;

C#

mydate3 = (mydate - mydate2).ToString(); // ToString returns a String.

mydate3 is a DateTime and you are trying to assign a String to it.

C#

if (x("Selected") + 1 == x("correct")

You might need to explicitly convert x("Selected") and x("correct") to ints. They are now objects.

C#

if (Convert.ToInt32(x("Selected")) + 1 == Convert.ToInt32(x("correct"))

Solution 2

Index accessors in c# are between brackets and not parenthesis =>

if (Convert.ToInt32(x["Selected"]) + 1 == Convert.ToInt32(x["correct"])

if (Convert.ToInt32(x["Selected"]) + 1 == Convert.ToInt32(x["correct"])

this also not working
