public sealed class EditorAttribute : Attribute

[<System.AttributeUsage(System.AttributeTargets.All, AllowMultiple=true, Inherited=true)>]

示例

下面的代码示例创建 MyImage 类。 类标有 一个 EditorAttribute ，该类指定 ImageEditor 为其编辑器。

[Editor("System.Windows.Forms.ImageEditorIndex, System.Design",
UITypeEditor::typeid)]
public ref class MyImage{
   // Insert code here.
};

[Editor("System.Windows.Forms.ImageEditorIndex, System.Design", 
    typeof(UITypeEditor))]

public class MyImage
{
    // Insert code here.
 }

<Editor("System.Windows.Forms.ImageEditorIndex, System.Design", _
    GetType(UITypeEditor))> _
Public Class MyImage
    ' Insert code here.
End Class

下面的代码示例创建 类的 MyImage 实例，获取 类的属性，然后打印 所使用的 myNewImage编辑器的名称。

int main()
{
   // Creates a new component.
   MyImage^ myNewImage = gcnew MyImage;

   // Gets the attributes for the component.
   AttributeCollection^ attributes = TypeDescriptor::GetAttributes( myNewImage );

   /* Prints the name of the editor by retrieving the EditorAttribute 
       * from the AttributeCollection. */
   EditorAttribute^ myAttribute = dynamic_cast<EditorAttribute^>(attributes[ EditorAttribute::typeid ]);
   Console::WriteLine( "The editor for this class is: {0}", myAttribute->EditorTypeName );
   return 0;
}

public static int Main() {
    // Creates a new component.
    MyImage myNewImage = new MyImage();
 
    // Gets the attributes for the component.
    AttributeCollection attributes = TypeDescriptor.GetAttributes(myNewImage);
 
    /* Prints the name of the editor by retrieving the EditorAttribute 
     * from the AttributeCollection. */
    
    EditorAttribute myAttribute = (EditorAttribute)attributes[typeof(EditorAttribute)];
    Console.WriteLine("The editor for this class is: " + myAttribute.EditorTypeName);
 
    return 0;
 }

Public Shared Sub Main()
    ' Creates a new component.
    Dim myNewImage As New MyImage()
    
    ' Gets the attributes for the component.
    Dim attributes As AttributeCollection = TypeDescriptor.GetAttributes(myNewImage)
    
    ' Prints the name of the editor by retrieving the EditorAttribute
    ' from the AttributeCollection. 
    
    Dim myAttribute As EditorAttribute = CType(attributes(GetType(EditorAttribute)), EditorAttribute)
    Console.WriteLine(("The editor for this class is: " & myAttribute.EditorTypeName))

End Sub

注解

编辑属性时，可视化设计器应通过对话框或下拉窗口创建指定编辑器的新实例。

EditorBaseTypeName使用 属性查找此编辑器的基类型。 唯一可用的基类型是 UITypeEditor。

EditorTypeName使用 属性获取与此属性关联的编辑器类型的名称。
