Repairs any errors identified during validation that cause the component to return VS_NEEDSNEWMETADATA at design time.
Espace de noms : Microsoft.SqlServer.Dts.Pipeline

Syntaxe
'Déclaration
Public Overridable Sub ReinitializeMetaData
'Utilisation
Dim instance As PipelineComponent
instance.ReinitializeMetaData()
public virtual void ReinitializeMetaData()
public:
virtual void ReinitializeMetaData()
abstract ReinitializeMetaData : unit -> unit
override ReinitializeMetaData : unit -> unit
public function ReinitializeMetaData()
Notes
The ReinitializeMetaData method is called in response to the component returning VSNEEDSNEWMETADATA from Validate. Components should implement code that fixes these errors.
Exemples
public override DTSValidationStatus Validate()
{
if (!ComponentMetaData.AreInputColumnsValid)
return DTSValidationStatus.VS_NEEDSNEWMETADATA;
}
public override void ReinitializeMetaData()
{
if (!ComponentMetaData.AreInputColumnsValid)
ComponentMetaData.RemoveInvalidInputColumns();
}
Public Overrides Function Validate() As DTSValidationStatus
If Not ComponentMetaData.AreInputColumnsValid Then
Return DTSValidationStatus.VS_NEEDSNEWMETADATA
End If
End Function
Public Overrides Sub ReinitializeMetaData()
If Not ComponentMetaData.AreInputColumnsValid Then
ComponentMetaData.RemoveInvalidInputColumns
End If
End Sub
