How to get items in listbox in to Settings.Default C#

Question

我试图在Settings.Default中保存列表框中的项目，但它不起作用，这是我到目前为止。

test.Properties.Settings.Default.list = listBox1.Items;

Answer 1

Changes to properties will not persist if you don't call Save() afterwards.

test.Properties.Settings.Default.list = listBox1.Items;
test.Properties.Settings.Default.Save();

Answer 2

Have you tried with an ArrayList ?

test.Properties.Settings.Default.list = new ArrayList(listBox1.Items);
test.Properties.Settings.Default.Save();

Then you could load the list back like so:

listBox1.Items.AddRange(test.Properties.Settings.Default.list.ToArray());

I'm also assuming that the items in your list are serializable (either implement ISerializable or have the SerializableAttribute ).
