TryGetValue(Guid,SampledMetricDefinition) Method

In This Topic

Retrieve a SampledMetricDefinition by its Id, if present. (Throws an ArgumentException if the Id resolves to an EventMetricDefinition instead.)

Syntax

Visual Basic
C#

'Declaration
 
Public Overloads Shared Function TryGetValue( _
   ByVal id As Guid, _
   ByRef value As SampledMetricDefinition _
) As Boolean

public static bool TryGetValue( 
   Guid id,
   out SampledMetricDefinition value
)

Parameters

id: The Id of the sampled metric definition to get.
value: The output variable to receive the SampledMetricDefinition object if found (null if not).

Return Value

False if no metric definition is registered with the given Id, true if a SampledMetricDefinition is registered with the given Id, or throws an exception if the registered definition is not a SampledMetricDefinition.

Remarks

This method looks in the collection of registered metric definitions for the specified Id key. If it is not found, the output is set to null and the method returns false. If the Id key is found and resolves to a SampledMetricDefinition, it is stored in the value output parameter and the method returns true. If the Id key is found but is not a SampledMetricDefinition, an ArgumentException is thrown to signal a usage inconsistency in your code.

Requirements

Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
