Next, we are going to make the Label1 to uppercase and the Label2 to lowercase. Follow this line of code and paste it to your Form1 Load.

[vbnet]

Public Class Form1
Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
Label1.Text = "itsourcecode.com".ToUpper
Label2.Text = "itsourcecode.com".ToLower
End Sub
End Class

[/vbnet]

Now, reload your project and see the results.

Here’s mine:

You would notice that our Label1 text is being modified into capital letters because of the string property .ToUpper.

Also, our Label2 text is being modified into small letters because of the string property .ToLower.

Take note of this string properties that can make your texts to uppercase and lowercase in VB.Net.

string.ToUpper – lets your texts loaded as capital letters.
string.ToLower – lets your texts loaded as small letters.

You can use these properties as you like as long as it is a string data type.

Congratulations! You have learned how to do Uppercase and Lowercase in VB.Net.
