Capitalize the First Letter of a Word in C#

I noticed that a few of my labels in the right column were in lower-case. Since I wrote my own label control, I decided to add a line of code to make sure the first letter in each tag was capitalized.

string labelName;
labelName = char.ToUpper(labelName[0]) + labelName.Substring(1);

Labels: Csharp, Strings

Yeah, but what if the first name consists of two words. E.g. "Amy Jo"

Split the string into an array (space delimiter) and then run the code on each word and build the string back.

Hi! Heres my Friendly name method used in my base class..
[XmlElement("friendlyname")]
public string FriendlyName
{

get
{
if (_friendlyName == "")
{
//_friendlyName = _name;
//char[] chars = _name.ToCharArray();

_friendlyName = _baseName;
char[] chars = _baseName.ToCharArray();

if (chars.Length > 0)
{

StringBuilder sb = new StringBuilder();
sb.Append(chars[0].ToString().ToUpper());
char lowerBound = 'A';
char upperBound = 'Z';
char spaceChar = ' ';

for (int i = 1; i < chars.Length; i++)
//foreach (char character in chars)
{
if (chars[i] == spaceChar)
{
sb.Append(chars[i].ToString());
continue;
}

if (chars[i - 1] == spaceChar)
chars[i] = Convert.ToChar(chars[i].ToString().ToUpper());

if ((chars[i] >= lowerBound && chars[i] <= upperBound))
{
if (chars[i - 1] != spaceChar)
sb.Append(" ");

sb.Append(chars[i].ToString());
}
else
{
sb.Append(chars[i].ToString());
}
}
_friendlyName = sb.ToString();
}
return _friendlyName;
}
return _friendlyName;
}
set
{
if (_friendlyName != value)
{
_friendlyName = value;
}
}
}
string _friendlyName = "";
