Namespace:   System.ComponentModel
Assembly:  System (in System.dll)


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


Initializes a new instance of the EditorAttribute class with the default editor, which is no editor.

System_CAPS_pubmethodEditorAttribute(String, String)

Initializes a new instance of the EditorAttribute class with the type name and base type name of the editor.

System_CAPS_pubmethodEditorAttribute(String, Type)

Initializes a new instance of the EditorAttribute class with the type name and the base type.

System_CAPS_pubmethodEditorAttribute(Type, Type)

Initializes a new instance of the EditorAttribute class with the type and the base type.


Gets the name of the base class or interface serving as a lookup key for this editor.


Gets the name of the editor class in the Type.AssemblyQualifiedName format.


Gets a unique ID for this attribute type.(Overrides Attribute.TypeId.)


Returns whether the value of the given object is equal to the current EditorAttribute.(Overrides Attribute.Equals(Object).)


Gets the Type of the current instance.(Inherited from Object.)


When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class.(Inherited from Attribute.)


When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.(Inherited from Attribute.)


Returns a string that represents the current object.(Inherited from Object.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr)

Maps a set of names to a corresponding set of dispatch identifiers.(Inherited from Attribute.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.GetTypeInfo(UInt32, UInt32, IntPtr)

Retrieves the type information for an object, which can be used to get the type information for an interface.(Inherited from Attribute.)


Retrieves the number of type information interfaces that an object provides (either 0 or 1).(Inherited from Attribute.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr)

Provides access to properties and methods exposed by an object.(Inherited from 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 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;
