範例

下列程式碼範例示範建構 ImageList 、將影像新增至 Images 屬性、設定 ImageSize 屬性,以及使用 Draw 方法。 若要執行此範例,請將它放在包含名為 Button1 之按鈕的表單中。 此範例假設 c:\Windows有FeatherTexture.bmp和消失Fishing.bmp \ 。 如果點陣圖不存在於您的系統上,或存在於另一個位置,請據以變更範例。

備註

Icon會先轉換成 , Bitmap 再將它新增至清單。

適用於

Add(Image)

將指定的影像加入 ImageList

public:
 void Add(System::Drawing::Image ^ value);
public void Add (System.Drawing.Image value);
member this.Add : System.Drawing.Image -> unit
Public Sub Add (value As Image)

參數

value
Image

要加入至清單的影像 Bitmap

例外狀況

要加入的影像是 null

要加入的影像不是 Bitmap

適用於

Add(Image, Color)

將指定的影像加入 ImageList,並使用指定的色彩來產生遮罩。

public:
 int Add(System::Drawing::Image ^ value, System::Drawing::Color transparentColor);
public int Add (System.Drawing.Image value, System.Drawing.Color transparentColor);
member this.Add : System.Drawing.Image * System.Drawing.Color -> int
Public Function Add (value As Image, transparentColor As Color) As Integer

參數
