Definition

Namespace:

System.EnterpriseServices.CompensatingResourceManager

Assembly:

System.EnterpriseServices.dll

Übermittelt während der Vorbereitungsphase einen Protokolldatensatz in der Reihenfolge der Übertragung.

public:
 virtual bool PrepareRecord(System::EnterpriseServices::CompensatingResourceManager::LogRecord ^ rec);

public virtual bool PrepareRecord (System.EnterpriseServices.CompensatingResourceManager.LogRecord rec);

abstract member PrepareRecord : System.EnterpriseServices.CompensatingResourceManager.LogRecord -> bool
override this.PrepareRecord : System.EnterpriseServices.CompensatingResourceManager.LogRecord -> bool

Public Overridable Function PrepareRecord (rec As LogRecord) As Boolean

Parameter

rec

LogRecord

Der zu übermittelnde Protokolldatensatz.

Gibt zurück

Boolean

true, wenn der übermittelte Datensatz übergangen werden soll, andernfalls false.

Beispiele

Im folgenden Codebeispiel wird die Implementierung dieser Methode veranschaulicht.

public:
    virtual bool PrepareRecord(LogRecord^ log) override 
    {

        // Check the validity of the record.
        if (log == nullptr)
        {
            return false;
        }
        array<Object^>^ record = dynamic_cast<array<Object^>^>(log->Record);
        if (record == nullptr)
        {
            return false;
        }
        if (record->Length != 2)
        {
            return false;
        }

        // The record is valid.
        receivedPrepareRecord = true;
        return true;              
    }

public override bool PrepareRecord (LogRecord log)
{

    // Check the validity of the record.
    if (log == null) return(true);
    Object[] record = log.Record as Object[];
    if (record == null) return(true);
    if (record.Length != 2) return(true);

    // The record is valid.
    receivedPrepareRecord = true;
    return(false);
}

Public Overrides Function PrepareRecord(ByVal log As LogRecord) As Boolean
