LogRecord Class

Represents an unstructured log record delivered as a COM+ CrmLogRecordRead structure. This class cannot be inherited.


Namespace:  System.EnterpriseServices.CompensatingResourceManager
Assembly:  System.EnterpriseServices (in System.EnterpriseServices.dll)

public sealed class LogRecord

The LogRecord type exposes the following members.

Public propertyFlagsGets a value that indicates when the log record was written.
Public propertyRecordGets the log record user data.
Public propertySequenceThe sequence number of the log record.

Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

Unstructured log records are delivered as a COM+ CrmLogRecordRead structure. In addition to the user data (a single BLOB), this contains additional fields that are useful for debugging or fault finding. The Flags field is a bit field that provides further information about whether this record was forgotten at some point, and when it was written. The Sequence field provides the sequence number of the log record. In most cases, sequence numbers are sequential but are not necessarily contiguous due to internal log records that are not delivered to the Compensating Resource Manager (CRM) Compensator.

The following code example demonstrates the use of this class.

public override bool AbortRecord (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);

    // Extract old account data from the record.
    string filename = (string) record[0];
    int balance = (int) record[1];

    // Restore the old state of the account.
    AccountManager.WriteAccountBalance(filename, balance);
