A suggestion to add to the solutions below - store dates on your database as DateTime or Date column types in preference to varchars - you can take advantage of database-side calculations and avoid the pitfalls of date formatting (especially across cultures)

Hi,

Try below code.

C#

DateTime dt1 = DateTime.ParseExact(In1, "HH:mm:ss", new DateTimeFormatInfo());
DateTime dt2 = DateTime.ParseExact(Out1, "HH:mm:ss", new DateTimeFormatInfo());
TimeSpan ts = dt1.Subtract(dt2);

C#

DateTime in1 = DateTime.Parse(dt_display.Rows[i]["In1"].ToString());
                    DateTime out1 = DateTime.Parse(dt_display.Rows[i]["Out1"].ToString());
                    TimeSpan diff = out1.Subtract(in1);

You can use timespan[^] to calculate time diff in c#.
Have a look:

C#

DateTime dt1=Textbox1.Text; 
DateTime dt2=Textbox2.Text; 

TimeSpan t=dt2.Subtract(dt1);

string diff = t.Hours.ToString()+":"+t.Minutes.ToString() + ":" + t.Seconds.ToString();
