Capitalize first letter for words with length over 2 chars C#

using System;
using System.Text.RegularExpressions;

public class Program
{
    public static void Main()
    {
        string[] parts = "university of washington".Split(' ');

        for(int i = 0; i < parts.Length; i++)
        {
            Match match = Regex.Match(parts[i], @"\w{3,}",RegexOptions.IgnoreCase);
            if (match.Success)
            {
                // Check for empty string.
                if (!string.IsNullOrEmpty(parts[i]))
                {
                    parts[i] = char.ToUpper(parts[i][0]) + parts[i].Substring(1);
                }
            }
        }

        string result = string.Join(" ", parts);        
        Console.WriteLine(result);
    }
}

//input - university of washington
//out put - University of Washington

This could be tweaked for any length you need by changing/adding a length parameter on the Regex.

ps:Didn't use LINQ cause it had to run on a older version of .Net framework.

Say Thanks
