.ToTitleCase not working on all upper case string

Question

Public Function TitleCase(ByVal strIn As String)
      Dim result As String = \"\"
      Dim culture As New CultureInfo(\"en\", False)
      Dim tInfo As TextInfo = cult         


        

Answer 1

If memory serves, ToTitleCase() never seemed to work for all capitalized strings. It basically requires you to convert the string to lowercase prior to processing.

From the MSDN:

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.

Workaround Usage (in C#):

string yourString = "TEST";

TextInfo formatter = new CultureInfo("en-US", false).TextInfo;    
formatter.ToTitleCase(yourString.ToLower());
