    {
        public int Compare(string x, string y)
        {
            Version verX = new Version(x);
            Version verY = new Version(y);
            return verX.CompareTo(verY);
        }
    }
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {

            List<string> versions = new List<string> { "1.1.0", "2.5", "2.1.5", "2.0", "10.1" };
            versions.Sort(new VersionSorter());

            foreach (var version in versions)
            {
                Console.WriteLine(version);
            }


        }
    }
}

输出结果：
