ToTitleCase

This C# method makes each word in a string title case—it capitalizes each word in a string. No custom code is needed to call ToTitleCase.

You could develop character-based algorithms to accomplish this goal. But the System.Globalization namespace provides ToTitleCase, which can be simpler.

Required output

Consider a simple string in C# like "purple fish." The string has 2 words separated with a space. Each word should have an uppercase letter.

purple fish -> Purple Fish

Example

This program shows how to call ToTitleCase. To access CultureInfo, you need to include the System.Globalization namespace. The input here is "purple fish."

using System;
using System.Globalization;

class Program
{
    static void Main()
    {
        string value = "purple fish";
        string titleCase = CultureInfo.CurrentCulture.TextInfo.ToTitleCase(value);
        Console.WriteLine(titleCase);
    }
}
Purple Fish

Discussion

When should ToTitleCase be used? Programs often have edge cases. A custom implementation can provide better support for certain words.

We looked at the ToTitleCase method on the TextInfo type. ToTitleCase can simplify your program, but it cannot be easily customized.
