Tutorial :What is the most efficient way to place a list of drives in a ComboBox using C#?


I am creating a program that allows the user to select a drive letter from a combo box. I am debating between populating the box using a list or an array. What is the best and most efficient way to do this?


For populating it, there is no discernible difference between a list and an array.

Personally, I would use a list as it is generally easier to use (can add/remove items, no fixed length etc.), and with generics, there is type safety just like an array. I know this has no difference in binding it to a list, but it makes it easier getting to that point.


'Efficient' is never going to be an issue here, with a max of 26 letters.

The combobox is going to copy to an internal list anyway, so as a source you can use whatever is most convenient.


I would do the following:


For the amount of drives you are going to have its hardly going to make a difference what way you do it.


Pretty simple:

ComboBox cb = new ComboBox();    string[] drives = Environment.GetLogicalDrives();    foreach (string drive in drives)  {      cb.Items.add(drive);  }
