C# 枚举字符串转换

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;
        }
