Convert all string into uppercase of a given string

   
 
     


Introduction :

In this tutorial we will see how convert a string to all lower case using ToUpper() method of string class in .NET Framework using C# and vb.net code example.

ToUpper() method of the string class is used to convert the whole word, sentence to the upper case. This is good practice to check the two string after converting either all upper case or all lowercase using ToLower() to ToUpper() method.

C# Code sample:

using System;

namespace DotNetSparkTutorials
{
    class Program
    {
        static void Main(string[] args)
        {
            // Declare string ;
            string strValue = "DotNetSpark";

            // return the result string in uppercase using ToUpper() Method of string class
            string strResult = strValue.ToUpper();

            //Display the all the upper case value of a given string
            Console.WriteLine(strResult);

            Console.ReadLine();

        }
    }
}

Output:

DOTNETSPARK

VB.NET Code example:

Namespace DotNetSparkTutorials
	Class Program
		Private Shared Sub Main(args As String())
			' Declare string ;
			Dim strValue As String = "DotNetSpark"

			' return the result string in uppercase using ToUpper() Method of string class
			Dim strResult As String = strValue.ToUpper()

			'Display the all the upper case value of a given string
			Console.WriteLine(strResult)

			Console.ReadLine()

		End Sub
	End Class
End Namespace

Output:

DOTNETSPARK
