C# ile metindeki ilk harfleri büyütmek

private string IlkHarfleriBuyut(string metin)
{
System.Globalization.CultureInfo cultureInfo = System.Threading.Thread.CurrentThread.CurrentCulture;
System.Globalization.TextInfo textInfo = cultureInfo.TextInfo;
return textInfo.ToTitleCase(metin);
}


bu kadar basit...:)
