Contoh

Contoh kode berikut menunjukkan bagaimana GetComponentView metode digunakan.

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)  
        {  
            // Create the package.  
            Package p = new Package();  

            // Add the data flow task.  
            MainPipe mp = ((TaskHost)p.Executables.Add("DTS.Pipeline")).InnerObject as MainPipe;  

            // Add the OLEDB Source component.  
            IDTSComponentMetaData100 mdOleDbSrc = mp.ComponentMetaDataCollection.New();  
            mdOleDbSrc.ComponentClassID = "DTSAdapter.OleDbSource";  
            mdOleDbSrc.Name = "OLEDB Source";  

            IDTSComponentView100 oledbView = mdOleDbSrc.GetComponentView();  

            mdOleDbSrc.Name = "The OLEDB Source Component";  

            Console.WriteLine(mdOleDbSrc.Name);  

            oledbView.Cancel();  

            Console.WriteLine(mdOleDbSrc.Name);  
        }  
    }  
}  

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").InnerObject, TaskHost), MainPipe)  
     Dim mdOleDbSrc As IDTSComponentMetaData100 = mp.ComponentMetaDataCollection.New   
     mdOleDbSrc.ComponentClassID = "DTSAdapter.OleDbSource"   
     mdOleDbSrc.Name = "OLEDB Source"   
     Dim oledbView As IDTSComponentView100 = mdOleDbSrc.GetComponentView   
     mdOleDbSrc.Name = "The OLEDB Source Component"   
     Console.WriteLine(mdOleDbSrc.Name)   
     oledbView.Cancel   
     Console.WriteLine(mdOleDbSrc.Name)   
   End Sub   
 End Class   
End Namespace

Keterangan

Metode ini dipanggil untuk mengambil IDTSComponentView100 antarmuka komponen. Antarmuka ini memungkinkan modifikasi transaksional dilakukan pada metadata komponen. Modifikasi metadata komponen dipertahankan ketika Commit metode dipanggil, dan dikembalikan ketika metode dipanggil Cancel .
