示例1: FindMyString
Private Sub FindMyString(ByVal searchString As String)
' Ensure we have a proper string to search for.
If searchString <> String.Empty Then
' Find the item in the list and store the index to the item.
Dim index As Integer = listBox1.FindString(searchString)
' Determine if a valid index is returned. Select the item if it is valid.
If index <> -1 Then
listBox1.SetSelected(index, True)
Else
MessageBox.Show("The search string did not match any items in the ListBox")
End If
End If
End Sub示例2: FindAllOfMyString
Private Sub FindAllOfMyString(ByVal searchString As String)
' Set the SelectionMode property of the ListBox to select multiple items.
listBox1.SelectionMode = SelectionMode.MultiExtended
' Set our intial index variable to -1.
Dim x As Integer = -1
' If the search string is empty exit.
If searchString.Length <> 0 Then
' Loop through and find each item that matches the search string.
Do
' Retrieve the item based on the previous index found. Starts with -1 which searches start.
x = listBox1.FindString(searchString, x)
' If no item is found that matches exit.
If x <> -1 Then
' Since the FindString loops infinitely, determine if we found first item again and exit.
If ListBox1.SelectedIndices.Count > 0 Then
If x = ListBox1.SelectedIndices(0) Then
Return
End If
End If
' Select the item in the ListBox once it is found.
ListBox1.SetSelected(x, True)
End If
Loop While x <> -1
End If
End Sub
