C# String Format for hours and minutes from decimal
(3 answers)
Closed 9 years ago.
If I have a double like 2.75, is there a way in .Net to format it as '2:45'
If it is for example, 2.75555555555, it should round it to the nearest minute.
I would not mind coding this myself, but I am wondering if .Net can. I checked ToString but did not find anything.
Thanks
Use TimeSpan and its ToString formatter:
TimeSpan timespan = TimeSpan.FromHours(2.75);
string output = timespan.ToString("h\\:mm");
For example
TimeSpan.FromHours(2.75555).ToString("h\\:mm")
outputs
2:45

This is my code:
decimal test1 = 190.5m;
decimal test2 = 191.5m;
var testResult1 = Math.Round(test1, 0); // =190 It should be 191!!!!
var testResult2 = Math.Round(test2, 0); // =192 Correct.
Is there a way I could get the correct result? Maybe another library instead of System.Math?
This is by design. Albeit not what we have grown up with.

Parse exact custom time format?

I'm reading data from an excel file. The user can specify the time in one of the following formats:
1600
16:00
In the latter case, I can easily convert it to a timespan. How do I convert the first format to timespan? Is there a straightforward way than manipulating the string to convert to the latter and do it?
Use
TimeSpan span = TimeSpan.ParseExact("1600", new string[] {"hhmm", #"hh\:mm"}, CultureInfo.InvariantCulture);

Math.Round(ts.TotalSeconds);

I new here, I'm stuck with this problem when a have an array of strings with values of "120612" and "200612".
I need to convert the strings to a date format like this, "Tues 12 June, 2012". How will I do that?
Thanks in advance.
DateTime.ParseExact is probably what you're looking for:
DateTime.ParseExact("200612", "ddMMyy", System.Globalization.CultureInfo.CurrentCulture)

Is it there an build-in function which converts string in format "2.71e+006" to a number or I have to write my custom algorithm?
The Decimal Parse method has an overload you can use:
decimal d = Decimal.Parse("2.71e+006", System.Globalization.NumberStyles.Float);
You can also do the same for a Double.
