Parameter

connections
A collection of connections used by the task.

variableDispenser
A VariableDispenser object for locking variables.

events
An object that implements the IDTSInfoEvents interface for raising events (errors, warnings, and so on) during persistence.

log

eventInfos
An EventInfos.

logEntryInfos
TheLogEntryInfos collection used by the task.

refTracker
An object reference tracker.

Hinweise

For the FileSystemTask and all other stock tasks, use this method to set the log events of each task.

Beispiel

Task developers define custom events by overriding the InitializeTask method of the Task base class, and creating a new EventInfo. The following code sample shows the InitializeTask method of a custom task in which two custom events are created and added to the eventInfos collection.

public override void InitializeTask(Connections connections, VariableDispenser variables, IDTSInfoEvents events, IDTSLogging log, EventInfos eventInfos, LogEntryInfos logEntryInfos, ObjectReferenceTracker refTracker)
{
    this.eventInfos = eventInfos;
    string[] paramNames = new string[1];
    TypeCode[] paramTypes = new TypeCode[1]{TypeCode.Int32};
    string[] paramDescriptions = new string[1];

    paramNames[0] = "InitialValue";
    paramDescriptions[0] = "The value before increment.";

    this.eventInfos.Add("OnBeforeIncrement","Fires before the task increments the value.",true,paramNames,paramTypes,paramDescriptions);
    this.onBeforeIncrement = this.eventInfos["OnBeforeIncrement"];

    paramDescriptions[0] = "The value after increment.";
    this.eventInfos.Add("OnAfterIncrement","Fires after the initial value is updated.",true,paramNames, paramTypes,paramDescriptions);
    this.onAfterIncrement = this.eventInfos["OnAfterIncrement"];
}
