    普通方法

    这种方法尽管很SB但确实可以解决问题

     private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
            {
                string SelPath = "";
                switch (comboBox1.SelectedIndex)
                {
                    case 0: SelPath = System.Environment.GetFolderPath(System.Environment.SpecialFolder.ApplicationData); break;
                    case 1: SelPath = System.Environment.GetFolderPath(System.Environment.SpecialFolder.CommonApplicationData); break;
                    case 2: SelPath = System.Environment.GetFolderPath(System.Environment.SpecialFolder.LocalApplicationData); break;
                    case 3: SelPath = System.Environment.GetFolderPath(System.Environment.SpecialFolder.Cookies); break;
                    case 4: SelPath = System.Environment.GetFolderPath(System.Environment.SpecialFolder.Desktop); break;
                    case 5: SelPath = System.Environment.GetFolderPath(System.Environment.SpecialFolder.Favorites); break;
                    case 6: SelPath = System.Environment.GetFolderPath(System.Environment.SpecialFolder.History); break;
                    case 7: SelPath = System.Environment.GetFolderPath(System.Environment.SpecialFolder.InternetCache); break;
                    case 8: SelPath = System.Environment.GetFolderPath(System.Environment.SpecialFolder.Programs); break;
                    case 9: SelPath = System.Environment.GetFolderPath(System.Environment.SpecialFolder.MyComputer); break;
                    case 10: SelPath = System.Environment.GetFolderPath(System.Environment.SpecialFolder.MyMusic); break;
                    case 11: SelPath = System.Environment.GetFolderPath(System.Environment.SpecialFolder.MyPictures); break;
                    case 12: SelPath = System.Environment.GetFolderPath(System.Environment.SpecialFolder.Recent); break;
                    case 13: SelPath = System.Environment.GetFolderPath(System.Environment.SpecialFolder.SendTo); break;
                    case 14: SelPath = System.Environment.GetFolderPath(System.Environment.SpecialFolder.StartMenu); break;
                    case 15: SelPath = System.Environment.GetFolderPath(System.Environment.SpecialFolder.Startup); break;
                    case 16: SelPath = System.Environment.GetFolderPath(System.Environment.SpecialFolder.System); break;
                    case 17: SelPath = System.Environment.GetFolderPath(System.Environment.SpecialFolder.Templates); break;
                    case 18: SelPath = System.Environment.GetFolderPath(System.Environment.SpecialFolder.DesktopDirectory); break;
                    case 19: SelPath = System.Environment.GetFolderPath(System.Environment.SpecialFolder.Personal); break;
                    case 20: SelPath = System.Environment.GetFolderPath(System.Environment.SpecialFolder.MyDocuments); break;
                    case 21: SelPath = System.Environment.GetFolderPath(System.Environment.SpecialFolder.ProgramFiles); break;
                    case 22: SelPath = System.Environment.GetFolderPath(System.Environment.SpecialFolder.CommonProgramFiles); break;
                }
                Text = SelPath;
            }
                

    使用 Enum.Parse 方法 (Type, String)

    [ComVisibleAttribute(true)]
    public static Object Parse(
    	Type enumType,
    	string value
    )

    正解方法

    本来一句就可以解决的 所以坚决用一句代码解决

            private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
            {
                string SelPath = System.Environment.GetFolderPath(
                             (System.Environment.SpecialFolder)Enum.Parse(typeof(System.Environment.SpecialFolder), comboBox1.Text)
                            );
                Text = SelPath;
            }
