c# TimeSpan Converting Minutes to Hours

I am converting minutes into hours. So if I have minutes = 12534. The result should be 208:54. The below code fails to bring this result.

TimeSpan spWorkMin = TimeSpan.FromMinutes(12534);
string workHours = spWorkMin.ToString(@"hh\:mm");
Console.WriteLine(workHours);

The result is 16:54.

How to get it correct?

using System;

var days = 1; 
var hours = 23; //max 23
var min = 12; //max 59

var TotalMin = (days*24*60)+(hours*60)+min;

Console.WriteLine("TotalMins "+ TotalMin);

//return back to the original days,hours,minutes

var Days = (TotalMin/(24*60));
var _minutes = (TotalMin%(60*60));
var Hours = (_minutes/60);
var Minutes = _minutes - (Hours*60);

Console.WriteLine($"{Days} , {Hours} , {Minutes}");

Personnaly I use this:

public static double MinutsTohHours(int Minuti)
    {
        double Tempo = 0;
            Tempo = ((double)(Minuti % 60) / 100);
            var n = (double)Minuti / 60;
            return Math.Floor((double)Minuti / 60) + Tempo;
       
    }

var totalMinutes = 12534;
Console.WriteLine("{0:00}:{1:00}", totalMinutes / 60, totalMinutes % 60);

Or

var totalMinutes = 12534;
var time = TimeSpan.FromMinutes(totalMinutes);
Console.WriteLine("{0:00}:{1:00}", (int)time.TotalHours, time.Minutes);

See https://dotnetfiddle.net/gYEsj2 to play with this

From MSDN documentation:

The "hh" custom format specifier outputs the value of the TimeSpan::Hours property, which represents the number of whole hours in the time interval that is not counted as part of its day component.

One quick way of getting the result you want would be something like the following:

TimeSpan spWorkMin = TimeSpan.FromMinutes(12534);
string workHours = string.Format("{0}:{1:00}", (int)spWorkMin.TotalHours, spWorkMin.Minutes);
Console.WriteLine(workHours);

The correct way to use is not using the ToString overload of DateTime – because there is no possibility to show the TotalHours there – but the string.Format method:

string.Format("{0:00}:{1:00}", (int)spWorkMin.TotalHours, spWorkMin.Minutes);

You need use TimeSpan.TotalHours Property

The TotalHours property represents whole and fractional hours, whereas the Hours property represents whole hours.

    TimeSpan spWorkMin = TimeSpan.FromMinutes(12534);
    string workHours = spWorkMin.ToString(@"hh\:mm");
    Console.WriteLine(spWorkMin.TotalHours);

TimeSpan spWorkMin = TimeSpan.FromMinutes(12534);
string workHours = string.Format("{0}:{1}", (int)spWorkMin.TotalHours, spWorkMin.Minutes);
Console.WriteLine(workHours);

The format specifier hh will show the hour part, which is not the total hours. You have to manually create a string using TotalHours cast into ints to show it as you want and add the minutes to that.
