If you choose to use the TimeSpan, be aware about the Days part:

C#

TimeSpan t1 = TimeSpan.Parse("23:30");
TimeSpan t2 = TimeSpan.Parse("00:40:00");
TimeSpan t3 = t1.Add(t2);
Label1.Text = t3.ToString(); //to bind to label
Console.WriteLine(t3); // 1.00:10:00

With DateTime:

DateTime d1 = DateTime.Parse("23:30");
DateTime d2 = DateTime.Parse("00:40:00");
DateTime d3 = d1.Add(d2.TimeOfDay); 
Label2.Text = t3.ToString(); //to bind to label
Console.WriteLine(d3.TimeOfDay); // 00:10:00

Its very simple.
TimeSpan t1 = TimeSpan.Parse(variable1);
TimeSpan t2 = TimeSpan.Parse(variable2);
TimeSpan t3 = t1.Add(t2);
variable3=t3.ToString();
Label1.Text = t3.ToString(); //to bind to label
Console.WriteLine(t3); // 1.00:10:00

Solution 1

If you mean adding two dates this will help

C#

System.DateTime today = System.DateTime.Now;
System.TimeSpan duration = new System.TimeSpan(36, 0, 0, 0);
System.DateTime answer = today.Add(duration);
System.Console.WriteLine("{0:dddd}", answer);

you can find more details about this in links below

CS2011 I need sum of time in same date anyway thank you CS2011

CS2011 15-Feb-13 2:03am

if i understand you i think you need to add some Hr or min or second in the current time (or any time). TimeSpane has const for that.
for example if want to add Hr,min and sec you can use
TimeSpan(Int32, Int32, Int32) = Initializes a new instance of the TimeSpan structure to a specified number of hours, minutes, and seconds. and pass that to Add method. Hope this helps
