I am not sure what you are asking here. Converting a UInt to time? Or how to format a string using String.Format()?

i need somethin like output

private UInt32 _time=800;
public UInt32 Time
{

get{
TimeSpan t = TimeSpan.FromMinutes(_time);
_time= string.Format("{0:D2}H:{1:D2}M:{2:D2}S",
t.Hours,
t.Minutes,
t.Seconds);
return _time;
}

}

Bind to DataGridTextColumn in XAML, output should be like 08D:13H:20M:04S

thanks

Solution 1

TimeSpan.FromSeconds is what you need to turn this in to a time span on which you can call a formatted ToString in order to get the format you need. You need to add another gettable property that returns it.

C#

public string TheTime
{
   get
   {
       TimeSpan ts = TimeSpan.FromSeconds(_time);
       return ts.ToString("ddD:hhH:mmM:ssS");
   }
}

The literal characters need to be escaped:
"dd'D:'hh'H:'mm'M:'ss'S'"
OR
@"dd\D\:hh\H\:mm\M\:ss\S"

Solution 2

Solution 1 "ddD:hhH:mmM:ssS" is invalid and will not work. There is some default formatting that might do it for you, but if that will not work, then you can use some of the properties to create whatever format you want. A sample is as follows:

C#

public string Duration
{
    get
    {
        TimeSpan timeSpan = TimeSpan.FromSeconds(_seconds);
        return String.Format("{0:00}D:{1:00}H:{2:00}M:{3:00}S", timeSpan.Days, timeSpan.Hours, timeSpan.Minutes, timeSpan.Seconds);
    }
}
private int _seconds;

See http://msdn.microsoft.com/en-us/library/ee372286.aspx[^] for details. Unfortunately, there is no way to simplify custom formating with TimeSpans.

I have updated the answer with the letters.

Actually, custom formatting with TimeSpan is not difficult, it just needs appropriate attention to detail (like quoting literals).

Clifford Nelson 23-Aug-12 15:01pm

I found the reference: http://msdn.microsoft.com/en-us/library/ee372287.aspx. It is no where near as easy as with time formatting. So using timeSpan.ToString(@"dd\D\:hh\H\:mm\M\:ss\S") works

Kenneth was just a bit quicker.
It requires .Net 4 or later, or Silverlight.
