Generally, title casing converts the first character of a word to uppercase and the rest of the characters to lowercase. However, this method does not currently provide proper casing to convert a word that is entirely uppercase, such as an acronym. The following table shows the way the method renders several strings.
Input | Language | Expected result | Actual result |
|---|
war and peace | English | War and Peace | War And Peace |
Per anhalter durch die Galaxis | German | Per Anhalter durch die Galaxis | Per Anhalter Durch Die Galaxis |
les naufragés d'ythaq | French | Les Naufragés d'Ythaq | Les Naufragés D'ythaq |
The current implementation of the ToTitleCase()()() method yields an output string that is the same length as the input string. However, this behavior is not guaranteed and could change in a future implementation.
The following code example changes the casing of a string based on the English (United States) culture, with the culture name en-US.
Imports System
Imports System.Globalization
Public Class SamplesTextInfo
Public Shared Sub Main()
' Defines the string with mixed casing.
Dim myString As String = "wAr aNd pEaCe"
' Creates a TextInfo based on the "en-US" culture.
Dim myTI As TextInfo = New CultureInfo("en-US", False).TextInfo
' Changes a string to lowercase.
Console.WriteLine("""{0}"" to lowercase: {1}", myString, myTI.ToLower(myString))
' Changes a string to uppercase.
Console.WriteLine("""{0}"" to uppercase: {1}", myString, myTI.ToUpper(myString))
' Changes a string to titlecase.
Console.WriteLine("""{0}"" to titlecase: {1}", myString, myTI.ToTitleCase(myString))
End Sub 'Main
End Class 'SamplesTextInfo
'This code produces the following output.
'
'"wAr aNd pEaCe" to lowercase: war and peace
'"wAr aNd pEaCe" to uppercase: WAR AND PEACE
'"wAr aNd pEaCe" to titlecase: War And Peace
