In this article, we will learn how to capitalize on a first letter of each word in a string in C#. In C#, there is no built-in function to convert the string into a title case. String class does not have a method to do this. But there are many ways to Capitalize on the first letter of each word in a string. Here is some example to do this:
Method 1: In C#, you can capitalize on the first letter of each word in a string by using a method ToTitleCase() which is present in a TextInfo Class and this class belongs to System.Globalization namespace.
using System;
using System.Globalization;
namespace Tutorialsrack
{
class Program
{
/* How to Capitalize a First letter of Each word in a string in C# */
static void Main(string[] args)
{
Console.Write("Enter The String Need to be Capitalized: ");
string str = Console.ReadLine();
string titleCase = CultureInfo.CurrentCulture.TextInfo.ToTitleCase(str.ToLower());
//Print The Result
Console.WriteLine("Capitalized String: "+ titleCase);
//Hit ENTER to exit the program
Console.ReadKey();
}
}
}Enter The String Need to be Capitalized: tutorials rack
Capitalized String: Tutorials Rack
Enter The String Need to be Capitalized: TUTORIALS RACK
Capitalized String: Tutorials Rack
Method 2: In this method,
using System;
namespace Tutorialsrack
{
class Program
{
/* How to Capitalize a First letter of Each word in a string in C# */
static void Main(string[] args)
{
Console.Write("Enter The String Need to be Capitalized: ");
string str = Console.ReadLine();
string titleCase = CapitalizeFirstLetter(str);
//Print The Result
Console.WriteLine("Capitalized String: "+ titleCase);
//Hit ENTER to exit the program
Console.ReadKey();
}
static string CapitalizeFirstLetter(string value)
{
//In Case if the entire string is in UpperCase then convert it into lower
value = value.ToLower();
char[] array = value.ToCharArray();
// Handle the first letter in the string.
if (array.Length >= 1)
{
if (char.IsLower(array[0]))
{
array[0] = char.ToUpper(array[0]);
}
}
// Scan through the letters, checking for spaces.
// ... Uppercase the lowercase letters following spaces.
for (int i = 1; i < array.Length; i++)
{
if (array[i - 1] == ' ')
{
if (char.IsLower(array[i]))
{
array[i] = char.ToUpper(array[i]);
}
}
}
return new string(array);
}
}
