Label.ImageList 屬性

定義

命名空間:

System.Windows.Forms

組件:

System.Windows.Forms.dll

取得或設定包含顯示在 ImageList 控制項中的影像的 Label。

public:
 property System::Windows::Forms::ImageList ^ ImageList { System::Windows::Forms::ImageList ^ get(); void set(System::Windows::Forms::ImageList ^ value); };

public System.Windows.Forms.ImageList? ImageList { get; set; }

member this.ImageList : System.Windows.Forms.ImageList with get, set

Public Property ImageList As ImageList

屬性值

ImageList

儲存 ImageList 物件集合的 Image。 預設值是 null。

範例

下列程式碼範例示範如何建立 Label 具有三維框線的控制項，以及使用 ImageList 和 ImageIndex 屬性顯示的影像。 控制項也有指定助憶鍵字元的標題。 此範例程式碼會使用 PreferredHeight 和 PreferredWidth 屬性，在顯示控制項的表單上適當調整其大小 Label 。 此範例需要 ImageList 已建立並命名為 imageList1，且其已載入兩個映射。 此範例也需要程式碼位於表單內，且該表單中 System.Drawing 已將 命名空間新增至其程式碼。

public:
   void CreateMyLabel()
   {
      // Create an instance of a Label.
      Label^ label1 = gcnew Label;
      
      // Set the border to a three-dimensional border.
      label1->BorderStyle = System::Windows::Forms::BorderStyle::Fixed3D;
      // Set the ImageList to use for displaying an image.
      label1->ImageList = imageList1;
      // Use the second image in imageList1.
      label1->ImageIndex = 1;
      // Align the image to the top left corner.
      label1->ImageAlign = ContentAlignment::TopLeft;
      
      // Specify that the text can display mnemonic characters.
      label1->UseMnemonic = true;
      // Set the text of the control and specify a mnemonic character.
      label1->Text = "First &Name:";
      
      /* Set the size of the control based on the PreferredHeight and PreferredWidth values. */
      label1->Size = System::Drawing::Size( label1->PreferredWidth, label1->PreferredHeight );
      
      //...Code to add the control to the form...
   }

public void CreateMyLabel()
{
   // Create an instance of a Label.
   Label label1 = new Label();

   // Set the border to a three-dimensional border.
   label1.BorderStyle = System.Windows.Forms.BorderStyle.Fixed3D;
   // Set the ImageList to use for displaying an image.
   label1.ImageList = imageList1;
   // Use the second image in imageList1.
   label1.ImageIndex = 1;
   // Align the image to the top left corner.
   label1.ImageAlign = ContentAlignment.TopLeft;

   // Specify that the text can display mnemonic characters.
   label1.UseMnemonic = true;
   // Set the text of the control and specify a mnemonic character.
   label1.Text = "First &Name:";
   
   /* Set the size of the control based on the PreferredHeight and PreferredWidth values. */
   label1.Size = new Size (label1.PreferredWidth, label1.PreferredHeight);

   //...Code to add the control to the form...
}

Public Sub CreateMyLabel()
    ' Create an instance of a Label.
    Dim label1 As New Label()
       
    ' Set the border to a three-dimensional border.
    label1.BorderStyle = System.Windows.Forms.BorderStyle.Fixed3D
    ' Set the ImageList to use for displaying an image.
    label1.ImageList = imageList1
    ' Use the second image in imageList1.
    label1.ImageIndex = 1
    ' Align the image to the top left corner.
    label1.ImageAlign = ContentAlignment.TopLeft
     
    ' Specify that the text can display mnemonic characters.
    label1.UseMnemonic = True
    ' Set the text of the control and specify a mnemonic character.
    label1.Text = "First &Name:"
       
    ' Set the size of the control based on the PreferredHeight and PreferredWidth values. 
    label1.Size = New Size(label1.PreferredWidth, label1.PreferredHeight)

    '...Code to add the control to the form...
End Sub

備註

ImageIndex和 ImageList 屬性不能與 屬性同時 Image 使用。 ImageIndex當屬性和 ImageList 屬性用來顯示影像時， Image 屬性會設定為 null 。

注意

Label如果它仍在其他地方參考， ImageList 將不會進行垃圾收集。 將 ImageList 的 Label 屬性設定為 null ，以啟用有效率的垃圾收集。
