EventSource.IsEnabled Method

Definition

Namespace:

System.Diagnostics.Tracing

Assembly:

System.Diagnostics.Tracing.dll

Determines whether the current event source is enabled.

Overloads

IsEnabled()	Determines whether the current event source is enabled.
IsEnabled(EventLevel, EventKeywords)	Determines whether the current event source that has the specified level and keyword is enabled.
IsEnabled(EventLevel, EventKeywords, EventChannel)	Determines whether the current event source is enabled for events with the specified level, keywords and channel.

IsEnabled()

Source:

EventSource.cs

Determines whether the current event source is enabled.

public:
 bool IsEnabled();

public bool IsEnabled ();

member this.IsEnabled : unit -> bool

Public Function IsEnabled () As Boolean

Returns

Boolean

true if the current event source is enabled; otherwise, false.

IsEnabled(EventLevel, EventKeywords)

Source:

EventSource.cs

Determines whether the current event source that has the specified level and keyword is enabled.

public:
 bool IsEnabled(System::Diagnostics::Tracing::EventLevel level, System::Diagnostics::Tracing::EventKeywords keywords);

public bool IsEnabled (System.Diagnostics.Tracing.EventLevel level, System.Diagnostics.Tracing.EventKeywords keywords);

member this.IsEnabled : System.Diagnostics.Tracing.EventLevel * System.Diagnostics.Tracing.EventKeywords -> bool

Public Function IsEnabled (level As EventLevel, keywords As EventKeywords) As Boolean

Parameters

level

EventLevel

The level of the event source.

keywords

EventKeywords

The keyword of the event source.

Returns

Boolean

true if the event source is enabled; otherwise, false.

Remarks

The result of this method is only an approximation of whether a particular event is active. Use it to avoid expensive computation for logging when logging is disabled. Event sources may have additional filtering that determines their activity.

IsEnabled(EventLevel, EventKeywords, EventChannel)

Source:

EventSource.cs

Determines whether the current event source is enabled for events with the specified level, keywords and channel.

public:
 bool IsEnabled(System::Diagnostics::Tracing::EventLevel level, System::Diagnostics::Tracing::EventKeywords keywords, System::Diagnostics::Tracing::EventChannel channel);

public bool IsEnabled (System.Diagnostics.Tracing.EventLevel level, System.Diagnostics.Tracing.EventKeywords keywords, System.Diagnostics.Tracing.EventChannel channel);

member this.IsEnabled : System.Diagnostics.Tracing.EventLevel * System.Diagnostics.Tracing.EventKeywords * System.Diagnostics.Tracing.EventChannel -> bool

Public Function IsEnabled (level As EventLevel, keywords As EventKeywords, channel As EventChannel) As Boolean

Parameters

level

EventLevel

The event level to check. An event source will be considered enabled when its level is greater than or equal to level.

keywords

EventKeywords

The event keywords to check.

channel

EventChannel

The event channel to check.

Returns

Boolean

true if the event source is enabled for the specified event level, keywords and channel; otherwise, false.
