DefaultPropertyAttribute Class

Use the Name property to get the name of the default property.

For more information, see Attributes Overview and Extending Metadata Using Attributes.

The following example defines a control named MyControl. The class is marked with a DefaultPropertyAttribute that specifies MyProperty as the default property.

[DefaultProperty("MyProperty")]
 public class MyControl : Control {

    public int MyProperty {
       get {
          // Insert code here. 
          return 0;
       }
       set {
          // Insert code here.
       }
    }

    // Insert any additional code.

 }

The next example creates an instance of MyControl. Then it gets the attributes for the class, extracts the DefaultPropertyAttribute, and prints the name of the default property.

public static int Main() {
    // Creates a new control.
    MyControl myNewControl = new MyControl();

    // Gets the attributes for the collection.
    AttributeCollection attributes = TypeDescriptor.GetAttributes(myNewControl);

    /* Prints the name of the default property by retrieving the 
     * DefaultPropertyAttribute from the AttributeCollection. */
    DefaultPropertyAttribute myAttribute = 
       (DefaultPropertyAttribute)attributes[typeof(DefaultPropertyAttribute)];
    Console.WriteLine("The default property is: " + myAttribute.Name);

    return 0;
 }
