Changing a string to have first character uppercase and remainder lowercase

Question

I have strings like this:

var a = "abc";
var b = "DEF";
var c = "gHi";

is there a function that I can apply to the string to change it so the first character is an uppercase followed by lowercase?

ToTitleCase() is the ideal solution. You can find a link to creating an extension method below. Or for fun you could create one yourself ...

public string ToProperCase(string str)
{
    if (string.IsNullOrEmpty(str))
         return str;

    return str[0].ToUpper() + str.Substring(1).ToLower();
}

// or an extension method
public static string ToProperCase(this string str)
{
    if (string.IsNullOrEmpty(str))
         return str;

    return str[0].ToUpper() + str.Substring(1).ToLower();
}

Link to creating ToTitleCase() as an extension method on System.String:
