Examples

The following example marks MyClass with a ProvidePropertyAttribute that tells the compiler to create a property called MyProperty from the GetMyProperty and SetMyProperty methods.

C#

[ProvideProperty("MyProperty", typeof(Control))]
public class MyClass : IExtenderProvider {
    protected CultureInfo ciMine = null;
    // Provides the Get portion of MyProperty. 
    public CultureInfo GetMyProperty(Control myControl) {
        // Insert code here.
        return ciMine;
    }
    
    // Provides the Set portion of MyProperty.
    public void SetMyProperty(Control myControl, string value) {
        // Insert code here.
    }
    
    /* When you inherit from IExtenderProvider, you must implement the 
     * CanExtend method. */
    public bool CanExtend(Object target) {
        return(target is Control);
    }
    
    // Insert additional code here.
 }

Remarks

When you mark a class with this attribute, you tell the code generator to create an extender property with the name you provide. The marked class must implement IExtenderProvider. As a result, the new property can be used by other components in a container.

Within the marked class, you must implement Get <name> and Set <name> methods. For example, if you mark a class with [ProvideProperty("PropertyName")], you must implement GetPropertyName and SetPropertyName methods. To specify that the new property will be an extender property, you must implement from IExtenderProvider, you must also implement a CanExtend method.

Constructors

ProvidePropertyAttribute(String, String)	Initializes a new instance of the ProvidePropertyAttribute class with the name of the property and the type of its receiver.
ProvidePropertyAttribute(String, Type)	Initializes a new instance of the ProvidePropertyAttribute class with the name of the property and its Type.

Properties

PropertyName	Gets the name of a property that this class provides.
ReceiverTypeName	Gets the name of the data type this property can extend.
TypeId	Gets a unique identifier for this attribute.

Methods

Equals(Object)	Returns whether the value of the given object is equal to the current ProvidePropertyAttribute.
GetHashCode()	Returns the hash code for this instance.
GetType()	Gets the Type of the current instance. (Inherited from Object)
IsDefaultAttribute()	When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute)
Match(Object)	When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute)
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
ToString()	Returns a string that represents the current object. (Inherited from Object)
