Add colon to 24 hour time in C#?

Question

I have time stored in Db as 800,1600 format in separate column. I want to add colon in time before giving it to UI. Currently I am calculating the size and zero if size is three and using insert to add colon after 2 characters.

String.Insert(2,':');

Is there any better way to do the same?

Can you paste your sophisticated code (full one) to put colon into time? — Fka, Sep 26 '16 at 06:17

Use below code

string time = "800";
string s1= DateTime.ParseExact(time.PadLeft(4, '0') , "HHmm", CultureInfo.InvariantCulture).ToString("HH:mm");

Since OP has no preceding zero already it should be `Hmm` – Mathias R. Jessen Sep 26 '16 at 06:31
`Hmm` isn't working. zero needs to be appended – Akshey Bhat Sep 26 '16 at 06:33

`time.PadLeft(4, '0')` is nicer than that ternary :) – poke Sep 26 '16 at 06:39
