範例

下列程式碼範例會 Remove 使用 方法來從 myButton 伺服器控制項中刪除子控制項。 首先，程式碼會使用 Contains 方法來判斷 是否 myChildControl 包含在 物件中 ControlCollection ，如果是，則會將其移除。

// Use the Contains method to check whether
// a child control exists, and if it does,
// use the Remove method to delete it.        
if (myButton.Controls.Contains(myChildControl))
{
   myButton.Controls.Remove(myChildControl);
   msgRemove.Text = "You removed myLiteralControl.";
}
else msgRemove.Text="The control to remove does not exist." ;

' Use the Contains method to check whether
' a child control exists, and if it does,
' use the Remove method to delete it.        
If myButton.Controls.Contains(myChildControl)
   myButton.Controls.Remove(myChildControl)
   msgRemove.Text = "You removed myLiteralControl."
Else
   msgRemove.Text="The control to remove does not exist." 
End If
