매개 변수

  • allowEventHandlers
    유형: System. . :: . .Boolean
    A Boolean that indicates if the development tool will allow event handler objects to be created for the event. If true, event handler objects can be created for the event.
  • parameterNames
    유형: array<System. . :: . .String> [] () [] []
    An array of parameters passed to the event.
  • parameterTypes
    유형: array<System. . :: . .TypeCode> [] () [] []
    The type of each parameter in the parameterNames array.
  • parameterDescriptions
    유형: array<System. . :: . .String> [] () [] []
    An array that contains descriptions for each of the parameters in parameterNames.

예

The following example shows a custom event being 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"];
}

Public Overrides Sub InitializeTask(ByVal connections As Connections, ByVal variables As VariableDispenser, ByVal events As IDTSInfoEvents, ByVal log As IDTSLogging, ByVal eventInfos As EventInfos, ByVal logEntryInfos As LogEntryInfos, ByVal refTracker As ObjectReferenceTracker) 
    Me.eventInfos = eventInfos
    Dim paramNames(0) As String
    Dim paramTypes(0) As TypeCode = {TypeCode.Int32}
    Dim paramDescriptions(0) As String
    
    paramNames(0) = "InitialValue"
    paramDescriptions(0) = "The value before increment."
    
    Me.eventInfos.Add("OnBeforeIncrement", "Fires before the task increments the value.", True, paramNames, paramTypes, paramDescriptions)
    Me.onBeforeIncrement = Me.eventInfos("OnBeforeIncrement")
    
    paramDescriptions(0) = "The value after increment."
    Me.eventInfos.Add("OnAfterIncrement", "Fires after the initial value is updated.", True, paramNames, paramTypes, paramDescriptions)
    Me.onAfterIncrement = Me.eventInfos("OnAfterIncrement")
End Sub
