Label.ImageList Label.ImageList Label.ImageList Label.ImageList Property

定義

取得或設定包含顯示在 ImageList 控制項中的影像的 LabelGets or sets the ImageList that contains the images to display in the Label control.

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

儲存 ImageList 物件集合的 ImageAn ImageList that stores the collection of Image objects. 預設值為 nullThe default value is null.

範例

下列程式碼範例示範如何建立Label具有3d 框線的控制項,以及ImageList使用和ImageIndex屬性顯示的影像。The following code example demonstrates how to create a Label control that has a three-dimensional border and an image displayed using the ImageList and ImageIndex properties. 控制項也有一個標題,其中指定了助憶鍵字元。The control also has a caption with a mnemonic character specified. 範例程式碼會使用PreferredHeightPreferredWidth Label屬性,適當地將控制項的大小調整為顯示的表單上。The example code uses the PreferredHeight and PreferredWidth properties to properly size the Label control on the form on which it is displayed. 這個範例要求ImageList已建立並命名為 imageList1,且已載入兩個映射。This example requires that an ImageList has been created and named imageList1 and that it has loaded two images. 此範例也會要求程式碼必須在將System.Drawing命名空間加入其程式碼的表單中。The example also requires that the code is within a form that has the System.Drawing namespace added to its code.

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

和屬性不能與Image屬性同時使用。 ImageList ImageIndexThe ImageIndex and the ImageList properties cannot be used at the same time as the Image property. 當屬性和ImageList屬性用於Image顯示影像時,屬性會設定為nullImageIndexWhen the ImageIndex property and ImageList properties are used to display an image, the Image property is set to null.

注意

如果仍在其他地方參考, Label將不會進行垃圾收集。 ImageListThe Label will not be garbage collected if its ImageList is still referenced elsewhere. 將的Label null屬性設定為,以啟用有效率的垃圾收集。 ImageListSet the ImageList property of the Label to null to enable efficient garbage collection.
