Contoh

Contoh berikut menunjukkan peristiwa kustom yang ditambahkan ke EventInfos koleksi.

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
