Compensator.PrepareRecord(LogRecord) 方法

定義

命名空間:

System.EnterpriseServices.CompensatingResourceManager

組件:

System.EnterpriseServices.dll

在準備階段依轉寄順序傳送記錄檔資料錄。

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

參數

rec

LogRecord

要轉寄的記錄檔資料錄。

傳回

Boolean

如果應該忘記已傳送的資料錄，則為 true，否則為 false。

範例

下列程式代碼範例示範此方法的實作。

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
