下列程式碼範例示範如何使用
GetSelected
方法來判斷 中
ListBox
選取的專案，以選取未選取的專案，並取消選取選取的專案。 此範例也會示範如何使用
SelectionMode
屬性讓
ListBox
擁有多個選取的專案，並使用
Sorted
屬性來示範如何自動排序專案中
ListBox
的專案。 這個範例要求
ListBox
已將名為
listBox1
的 ，加入至表單，而且
InitializeMyListBox
從表單的 事件呼叫
Load
範例中定義的 方法。

Sorted
使用 屬性，在 中
ListBox
依字母順序自動排序字串。 當專案新增至已
ListBox
排序的 時，專案會移至排序清單中的適當位置。 將專案新增至
ListBox
時，先排序專案，然後新增專案會更有效率。
設定
ListBox
為
Sorted
true
的 ，不應使用
DataSource
屬性系結至資料。 若要在系結
ListBox
中顯示已排序的資料，您應該系結至支援排序的資料來源，並讓資料來源提供排序。
