Title case in C# using split()

I am writing a simple program that lets the user input a sentence and it gets converted to title case. The first letter in each word is made capital. When it runs I don't get any errors, but it doesn't convert. Can someone let me know what I am missing? Thanks in advance!

This is my .cs file:

using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { if (Page.IsPostBack) { Page.Validate(); if (!Page.IsValid) { string sentence = phrase.Text; String[] sentenceArray = sentence.Split(' '); for (int i = 0; i < sentenceArray.Length; i++) { sentenceArray[i] = sentenceArray[i].Substring(0, 1).ToUpper() + sentenceArray[i].Substring(1).ToLower(); } phrase.Text = String.Join(" ", sentenceArray); } } } }

If needed here is the HTML code:

<html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title>Convert to Title Case</title> </head> <body> <form id="form1" runat="server"> <div> <p> Enter a phrase and click the Title Case button.</p> <p> <asp:TextBox ID="phrase" runat="server" /> <asp:RequiredFieldValidator ID="letterValidator" runat="server" ErrorMessage="Required field" ControlToValidate="phrase" /> </p> <p> <asp:HiddenField ID="progress" runat="server" Value="**********" /> <asp:Button ID="convertToTitleCase" runat="server" Text="Title Case" /> </p> </div> </form> </body> </html>

-------------Problems Reply------------

A couple of comments:

  1. if (!Page.IsValid) - are you sure that's what you meant? Maybe if (Page.IsValid) is more like it.
  2. sentenceArray[i] = sentenceArray[i].Substring(0, 1).ToUpper() + sentenceArray[i].Substring(1).ToLower(); - what will happen if sentenceArray is empty (possible unless StringSplitOptions.RemoveEmptyEntries is given to String.Split)? - Either add StringSplitOptions.RemoveEmptyEntries as a parameter to String.Split - or add a check here.

Your code is executed only when page is not valid:

if (!Page.IsValid)

And your only validator is

<asp:RequiredFieldValidator ID="letterValidator"
runat="server" ErrorMessage="Required field" ControlToValidate="phrase" />

So, just remove the if (!Page.IsValid) condition and it will work correctly.

P.S.: And as it has been already pointed in another answer, you will have to be careful with Substring. At least use String.Split(string, StringSplitOptions) with StringSplitOptions.RemoveEmptyEntries to avoid index exception when someone enters string with two sequential spaces.
