Compensator.PrepareRecord(LogRecord) 方法

定义

命名空间:

System.EnterpriseServices.CompensatingResourceManager

程序集:

System.EnterpriseServices.dll

在准备阶段期间以前向顺序传递日志记录。

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

参数

rec

LogRecord

要转发的日志记录。

返回

Boolean

如果应忘记传递的记录，为 true；否则为 false。

示例

下面的代码示例演示此方法的实现。

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 
    
    ' Check the validity of the record.
    If log Is Nothing Then
        Return True
    End If
    Dim record As [Object]() = log.Record
    
    If record Is Nothing Then
        Return True
    End If
    If record.Length <> 2 Then
        Return True
    End If 
    ' The record is valid.
    receivedPrepareRecord = True
    Return False

End Function 'PrepareRecord
