Converting string to title case in C#

Question

I have a string which contains a mixture of upper and lower case characters, for example "a Simple string" . What I want to do is to convert first character of each word ( I can assume that words are separated by spaces) into upper case. So I want the result as "A Simple String". Is there any easy way to do this? I don't want to split the string and do the conversion (that will be my last resort). Also, it is guaranteed that the strings are in English.

Answer 1

TextInfo.ToTitleCase

Answer 2

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() );

Answer 3

 System.Globalization.CultureInfo.CurrentUICulture.TextInfo.ToTitleCase
