Getting Selected Items From WinForm ListBox?

I have a ListBox in a WinForm with multiselect enabled.

The selected开发者_JS百科 items appear to be stored in an object, how to I get their values?

Easy, depending on what type you stored:

foreach (MyItemType item in listBox1.SelectedItems)
{
   ...
}

Because this is an older, non-generic collection it is better not to use var to declare the item variable. That would only get you a reference of type object.

You can also use other properties like:

if (listBox1.SelectedItems.Count > 0)
   ...

Just use the following code to display the selected item from the ListBox - for WinForm app...

string s = listbox1.Text; //replace listbox1 with your listbox control

---

Try the SelectedItems property.

foreach (var selectedItem in listBox1.SelectedItems)
{
    ...
}

---

The selected items are found in the SelectedItems property. These are the objects that you added to the list box, so you can cast the objects to their respective type and access any members that way:

// get the first selected item, cast it to MyClass
MyClass item = listBox.SelectedItems[0] as MyClass;
if (item != null)
{
    // use item here
}
