IDTSPipeline100.GetNextPasteID()
Comentarios
The data flow task generates object IDs in sequence. This method retrieves the next available unique ID and increments.
Ejemplos
The following code example demonstrates the sequential creation of IDs assigned to data flow objects.
using System;
using Microsoft.SqlServer.Dts.Runtime;
using Microsoft.SqlServer.Dts.Pipeline.Wrapper;
namespace Microsoft.Samples.SqlServer.Dts
{
public class Class1
{
public static void Main(string []args)
{
Package p = new Package();
MainPipe mp = ((TaskHost)p.Executables.Add("DTS.Pipeline")).InnerObject as MainPipe;
for(int x=0; x<10; x++)
{
Console.WriteLine("NextPasteID: " + mp.GetNextPasteID());
Console.WriteLine("MetaDataID: " + mp. ComponentMetaDataCollection.New().ID);
}
}
}
}
Imports System
Imports Microsoft.SqlServer.Dts.Runtime
Imports Microsoft.SqlServer.Dts.Pipeline.Wrapper
Namespace Microsoft.Samples.SqlServer.Dts
Public Class Class1
Public Shared Sub Main(ByVal args As String())
Dim p As Package = New Package
Dim mp As MainPipe = CType(CType(p.Executables.Add("DTS.Pipeline"), TaskHost).InnerObject, MainPipe)
Dim x As Integer = 0
While x < 10
Console.WriteLine("NextPasteID: " + mp.GetNextPasteID)
Console.WriteLine("MetaDataID: " + mp.ComponentMetaDataCollection.New.ID)
System.Math.Min(System.Threading.Interlocked.Increment(x),x-1)
End While
End Sub
End Class
End Namespace
The above code generates the following output.
NextPasteID: 1
MetaDataID: 2
NextPasteID: 3
MetaDataID: 4
NextPasteID: 5
MetaDataID: 6
NextPasteID: 7
MetaDataID: 8
NextPasteID: 9
MetaDataID: 10
NextPasteID: 11
MetaDataID: 12
NextPasteID: 13
MetaDataID: 14
NextPasteID: 15
MetaDataID: 16
NextPasteID: 17
MetaDataID: 18
NextPasteID: 19
MetaDataID: 20
