普通方法

這種方法盡管很SB但確實可以解決問題

 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

本來一句就可以解決的 所以堅決用一句代碼解決

?

        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;}
