Proper Case Title Case Question

Question

What am i doing wrong here? I want the users name to be shown in the output as propercase but I cant figure it out.

string proper = this.xTripNameTextBox.Text;
CultureInfo properCase = System.Threading.Thread.CurrentThread.CurrentCulture;
TextInfo currentInfo = properCase.TextInfo;
proper = currentInfo.ToTitleCase(proper);

this.xTripOutputLabel.Text = proper +  Environment.NewLine + "The total gallons you would use: " + Output.ToString("0") + Environment.NewLine + "Total amount it will cost you: " + Coutput.ToString("C") + Environment.NewLine +" Your customer number is " + rnd1.Next(1, 1000).ToString();

When a user enters "JOHN DOE" I get "JOHN DOE" it's supposed to convert it to propercase "John Doe", but I don't know what im doing wrong — Michael Quiles, May 16 '10 at 15:23
That is the problem, use ToLower to first convert the string to lower case, then the Title casing will work. — Chris Taylor, May 16 '10 at 15:27

I have tested the following on an all upper case word at it works:

string proper = "TEST STRING";
CultureInfo properCase = System.Threading.Thread.CurrentThread.CurrentCulture;
TextInfo currentInfo = properCase.TextInfo;
proper = currentInfo.ToTitleCase(currentInfo.ToLower(proper));
// proper = "Test String"

So - change the string to lower case before calling ToTitleCase.

The MSDN documentation does say that a string that is all upper case (such as an acronym) will not be converted and the sample code provided in the post corroborates this.

That's according to spec, quote from the doc: However, this method does not currently provide proper casing to convert a word that is entirely uppercase

http://msdn.microsoft.com/en-us/library/system.globalization.textinfo.totitlecase.aspx

Without testing I'd guess that you could do it by first making it LowerCase and then TitleCase.

Seems right, I am using

return CultureInfo.CurrentCulture.TextInfo.ToTitleCase(text);

And it's working.

Try to force another culture info.
