Formatting time string

Feb 27, 2009 10:35 PM|LINK

Hello.

If you a int that can either be 2 - 4 in length, how would you format to look like this

13:45

So, the int can start like this:

12

and should be formatted like this:

:12

or if it start likes this:

112

it should end up like this:

1:12

Thanks!

The code was written using C# -- are you a VB person? (Murphy's Law at work here :-)

I can write it in VB.

Also, if someone enters 6 do you want it to be formatted as

:06

?

Hi Larry. Thanks for your reply. I was looking for a C# sample; and this works perfect!

My only wish would be something more elegant, I think this could be done in 2 lines of code. But hey, beggers can't be choosers right? Haha.

Thanks buddy.

If anyone wants to give it a go:

public static string FormatTime(string time)
    {
        string originalstring = time;
        int stringlength = originalstring.Length;


        string firstpart = originalstring.Substring(0, stringlength - 2);
        string secondpart = originalstring.Substring(stringlength - 2, 2);
        string result = firstpart + ":" + secondpart;


        return result;
    }

By the way, to answer your above question - this is to format the length of an MP3 file, so if its only "6" seconds, then yeah, it should look like ":06".

Please find below a version two at the end of this post. I'm chuckling too--I know what you mean about wanting to find shorter code, and for humor (these don't exist but I'm guessing you were thinking the same (OK, it takes 3 lines : - )

originalstring = TextBox1.Text;

int length = originalstring.Length;

smartstring = originalstring.SmartInsert(length-2, ":");

Hmmm... I'm wondering if we can build properties--like building .SmartInsert()...

Breaking News - Yes you can. I posted a question about it and someone gave me an answer that with some small changes produced a function .TakeFive() that would subtract 5 from any integer...

Are you working with classes in order to move functions and subroutines into classes (in the App_Code folder) -- if you haven't, you want to -- that works wonders for simplifying code on the code behind page.

Note: I ran into problem with computer errors if the length of the string was 1. However, because this was only going to happen for single digit entries, I decided to do try / catch and if if jumped to the catch part then we could simply have it do what it needed to do for a single digit result (we would have had to work this into our code anyway--in a way, we turned this into a simplification).

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;


public partial class Molley : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {


    }
    protected void Button_Click(object sender, EventArgs e)
    {
        string originalstring = InputTextBox.Text;
        string firstpart, secondpart;


        int stringlength = originalstring.Length;


        try
        {
            firstpart = originalstring.Substring(0, stringlength - 2);
            ResultLabel.Text = "firstpart " + firstpart;
        }
        catch
        {
            firstpart = "";
        }


        try
        {
            secondpart = originalstring.Substring(stringlength - 2, 2);
        }
        catch
        {
            secondpart = "0" + originalstring;
        }


         ResultLabel.Text = firstpart + ":" + secondpart;


    }
  

}
