[EventTrackingEnabled]
public class EventTrackingEnabledAttribute_Ctor : ServicedComponent
{
}

[EventTrackingEnabled(false)]
public class EventTrackingEnabledAttribute_Ctor_Bool : ServicedComponent
{
}

[EventTrackingEnabled(false)]
public class EventTrackingEnabledAttribute_Value : ServicedComponent
{
    public void ValueExample()
    {
        // Get the EventTrackingEnabledAttribute applied to the class.
        EventTrackingEnabledAttribute attribute =
            (EventTrackingEnabledAttribute)Attribute.GetCustomAttribute(
            this.GetType(),
            typeof(EventTrackingEnabledAttribute),
            false);

        // Display the value of the attribute's Value property.
        Console.WriteLine("EventTrackingEnabledAttribute.Value: {0}",
            attribute.Value);
    }
}

Constructors

EventTrackingEnabledAttribute()	Initializes a new instance of the EventTrackingEnabledAttribute class, enabling event tracking.
EventTrackingEnabledAttribute(Boolean)	Initializes a new instance of the EventTrackingEnabledAttribute class, optionally disabling event tracking.

Properties

TypeId	When implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute)
Value	Gets the value of the Value property, which indicates whether tracking is enabled.

Methods

Equals(Object)	Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute)
GetHashCode()	Returns the hash code for this instance. (Inherited from Attribute)
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)

Explicit Interface Implementations

_Attribute.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr)	Maps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute)
_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)
_Attribute.GetTypeInfoCount(UInt32)	Retrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute)
_Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr)	Provides access to properties and methods exposed by an object. (Inherited from Attribute)
