Contoh

Contoh kode berikut menemukan kolom output dalam buffer menggunakan FindColumnByLineageID. Indeks kolom disimpan dalam array anggota internal sehingga dapat diakses menggunakan PrimeOutput metode atau ProcessInput metode .

int []columnIndex;  
public override void PreExecute()  
{  
    IDTSOutput100 output = ComponentMetaData.OutputCollection[0];  

    columnIndex = new int[output.OutputColumnCollection.Count];  

    for(int x=0; x< output.OutputColumnCollection.Count; x++)  
    {  
        IDTSOutputColumn100 col = output.OutputColumnCollection[x];  
        columnIndex[x] = BufferManager.FindColumnByLineageID( output.Buffer,col.LineageID);  
    }  
}  

Private columnIndex As Integer()   

Public  Overrides Sub PreExecute()   
 Dim output As IDTSOutput100 = ComponentMetaData.OutputCollection(0)   
 columnIndex = New Integer(output.OutputColumnCollection.Count - 1) {}   
 Dim x As Integer = 0   
 While x < output.OutputColumnCollection.Count   
   Dim col As IDTSOutputColumn100 = output.OutputColumnCollection(x)   
   columnIndex(x) = BufferManager.FindColumnByLineageID(output.Buffer, col.LineageID)   
   x -= 1   
 End While   
End Sub  

Keterangan

Properti run-time ini terutama digunakan sebagai parameter untuk FindColumnByLineageID metode BufferManager properti untuk menemukan kolom dalam PipelineBuffer.
