Assembly:  System (in System.dll)

[AttributeUsageAttribute(AttributeTargets.All, AllowMultiple = true, Inherited = true)]
public sealed class EditorAttribute : Attribute

When editing the property, a visual designer should create a new instance of the specified editor through a dialog box or drop-down window.

Use the EditorBaseTypeName property to find this editor's base type. The only available base type is UITypeEditor.

Use the EditorTypeName property to get the name of the type of editor associated with this attribute.

For general information on using attributes. see Attributes Overview and Extending Metadata Using Attributes. For more information on design-time attributes, see Attributes and Design-Time Support.

The following code example creates the MyImage class. The class is marked with an EditorAttribute that specifies the ImageEditor as its editor.

[Editor("System.Windows.Forms.ImageEditorIndex, System.Design", 

public class MyImage
    // Insert code here.

The following code example creates an instance of the MyImage class, gets the attributes for the class, and then prints the name of the editor used by myNewImage.

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;
