WinForm中的统一皮肤样式是怎么实现的？

Question

百度一下Winform皮肤控件，可以搜到很多免费或收费的皮肤控件，使用起来方便简单，
只需要设置一个皮肤文件的路径即可！
但是这个控件怎么实现对项目中每一个用户创建的Form进行样式渲染？
难道控件可以监控我什么时间创建Form？ 这也太神奇了吧？

我经常就是常用控件自己重载下自己定义一个INI皮肤文件，
然后去读这个文件，读这个文件的方法是： public class ReadIniFile
    {
        // Methods
        public ReadIniFile()
        {
            this.path = Application.StartupPath;
            this.path = this.path + @"\SKIN.ini";
        }
        [DllImport("kernel32")]
        private static extern int GetPrivateProfileString(string section, string key, string def, StringBuilder retVal, int size, string filePath);        internal Color IniReadColor(string Section, string Key)
        {
            Color color1 = Color.Lavender;
            if (File.Exists(this.path))
            {
                try
                {
                    string text1 = ",";
                    StringBuilder builder1 = new StringBuilder(0xff);
                    ReadIniFile.GetPrivateProfileString(Section, Key, "", builder1, 0xff, this.path);
                    string text2 = builder1.ToString().Trim();
                    int num1 = text2.Length;
                    int num2 = text2.IndexOf(text1);
                    int num3 = Convert.ToInt32(text2.Substring(0, num2));
                    string text3 = text2.Substring(num2 + 1, (num1 - num2) - 1).Trim();
                    num1 = text3.Length;
                    int num4 = text3.IndexOf(text1);
                    int num5 = Convert.ToInt32(text3.Substring(0, num4));
                    int num6 = Convert.ToInt32(text3.Substring(num4 + 1, (num1 - num4) - 1));
                    color1 = Color.FromArgb(num3, num5, num6);
                }
                catch
                {
                    return color1;
                }
            }
            return color1;
        }
        internal bool IniReadRect(string Section, string Key, out int[] Num)
        {
            string text1 = ",";
            int[] numArray1 = new int[6];
            StringBuilder builder1 = new StringBuilder(0xff);
            ReadIniFile.GetPrivateProfileString(Section, Key, "", builder1, 0xff, this.path);
            int num1 = builder1.ToString().Length;
            int num2 = builder1.ToString().IndexOf(text1);
            int num3 = Convert.ToInt32(builder1.ToString().Substring(0, num2));
            string text2 = builder1.ToString().Substring(num2 + 1, (num1 - num2) - 1);
            num1 = text2.Length;
            int num4 = text2.IndexOf(text1);
            int num5 = Convert.ToInt32(text2.Substring(0, num4));
            string text3 = text2.ToString().Substring(num4 + 1, (num1 - num4) - 1);
            num1 = text3.Length;
            int num6 = text3.IndexOf(text1);
            int num7 = Convert.ToInt32(text3.Substring(0, num6));
            int num8 = Convert.ToInt32(text3.Substring(num6 + 1, (num1 - num6) - 1));
            numArray1[0] = num3;
            numArray1[1] = num5;
            numArray1[2] = num7;
            numArray1[3] = num8;
            Num = numArray1;
            return true;
        }
        internal string IniReadValue(string Section, string Key)
        {
            StringBuilder builder1 = new StringBuilder(0xff);
            ReadIniFile.GetPrivateProfileString(Section, Key, "", builder1, 0xff, this.path);
            return builder1.ToString();
        }
        // Fields
        private string path;
    }
