    //obj.UserDocumentList = ThidDb.UserDocument.Where(x => x.CreatedBy == UserId).ToList();
    {
        VM_TimeSheet ObjVM_TimeSheet = new VM_TimeSheet();
        int LoggedUser = User.KEY();
        string LoggedUserName = User.UserName();
        string UserEmail = User.EmailID();
        DateTime TimeIn, TimeOut;

        using (SecurenetDB SecurenetDB = new SecurenetDB())
        {
            ObjVM_TimeSheet.TimesheetList = SecurenetDB.AD_TimeSheet.Where(x => DbFunctions.TruncateTime(x.ActivityDate.Value) == DbFunctions.TruncateTime(CurrentDate) && x.UserKEY == LoggedUser).ToList();
            TimeIn = SecurenetDB.AD_CardPunching.Where(x => DbFunctions.TruncateTime(x.EventDate) == DbFunctions.TruncateTime(CurrentDate) && x.UserName == LoggedUserName).Select(x => x.Time_In).FirstOrDefault();
            TimeOut = SecurenetDB.AD_CardPunching.Where(x => DbFunctions.TruncateTime(x.EventDate) == DbFunctions.TruncateTime(CurrentDate) && x.UserName == LoggedUserName).Select(x => x.Time_Out).FirstOrDefault();
            TimeInn = TimeIn.ToString("hh:mm tt");
            TimeOuut = TimeOut.ToString("hh:mm tt");
            TotalTime = SecurenetDB.AD_CardPunching.Where(x => DbFunctions.TruncateTime(x.EventDate) == DbFunctions.TruncateTime(CurrentDate) && x.UserName == LoggedUserName).Select(x => x.TotalHours).FirstOrDefault();
            // ObjVM_TimeSheet.TimesheetList=SecurenetDB.AD_TimeSheet.Where(x=>x.Hours== TextTime && x.UserKEY == LoggedUser).ToList();
            var sum = "00:00";
            foreach(var iteam in ActivityTime)
            {

        }
        return Json(new
        {
            TimeSheetData = this.RenderPartialViewToString("TimeSheetData", ObjVM_TimeSheet.TimesheetList),
            TimeIn = TimeInn,
            TimeOut = TimeOuut,
            TotalTime = TotalTime
        }, JsonRequestBehavior.AllowGet);
    }

Use TimeSpan

    string[] times = new string[] {"02:30", "03:25", "00:45"};

    TimeSpan totalTime = new TimeSpan(0);
    
    foreach (string time in times)
    {
        TimeSpan ts = TimeSpan.Parse(time);
        totalTime += ts;
    }
    
    Console.WriteLine(totalTime.ToString(@"hh\:mm"));

Output

06:40
