NameDescription
System_CAPS_pubmethod EventSourceAttribute

Initializes a new instance of the EventSourceAttribute class.

NameDescription
System_CAPS_pubproperty

Gets or sets the event source identifier.

System_CAPS_pubproperty

Gets or sets the name of the localization resource file.

System_CAPS_pubproperty

Gets or sets the name of the event source.

System_CAPS_pubproperty

When implemented in a derived class, gets a unique identifier for this Attribute.(Inherited from Attribute.)

NameDescription
System_CAPS_pubmethod Equals

This API supports the product infrastructure and is not intended to be used directly from your code. Returns a value that indicates whether this instance is equal to a specified object.(Inherited from Attribute.)

System_CAPS_pubmethod GetHashCode

Returns the hash code for this instance.(Inherited from Attribute.)

System_CAPS_pubmethod GetType

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

System_CAPS_pubmethod 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.)

System_CAPS_pubmethod Match

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

System_CAPS_pubmethod ToString

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

NameDescription
System_CAPS_pubinterface System_CAPS_privmethod _AttributeGetIDsOfNames

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

System_CAPS_pubinterface System_CAPS_privmethod _AttributeGetTypeInfo

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

System_CAPS_pubinterface System_CAPS_privmethod _AttributeGetTypeInfoCount

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

System_CAPS_pubinterface System_CAPS_privmethod _AttributeInvoke

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

By default, in event tracing for Windows (ETW), the name of an event source matches the name of the event source class, but without the namespace name. This is sufficient for private event sources, but for more visible event sources it is better to have a hierarchical namespace such as: CompanyName.ProviderName. The EventSourceAttribute attribute lets you define the ETW name independently of the name of the class.

The EventSourceAttribute attribute also lets you define a GUID explicitly for the event source. In standard usage, you don’t need to specify a GUID when defining an event source or referring to it, because a GUID is implicitly derived from the name of the event source class. Explicitly defining a GUID is discouraged, except when upgrading existing ETW providers to using event sources.
