Try this:
string myText = "a Simple string";
string asTitleCase =
System.Threading.Thread.CurrentThread.CurrentCulture.TextInfo.
ToTitleCase(myText.ToLower());
As has already been pointed out, using TextInfo.ToTitleCase might not give you the exact results you want. If you need more control over the output, you could do something like this:
IEnumerable<char> CharsToTitleCase(string s)
{
bool newWord = true;
foreach(char c in s)
{
if(newWord) { yield return Char.ToUpper(c); newWord = false; }
else yield return Char.ToLower(c);
if(c==' ') newWord = true;
}
}
And then use it like so:
var asTitleCase = new string( CharsToTitleCase(myText).ToArray() );
