示例

以下代码示例演示了 GetComponentView 方法的使用方法。

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  

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);  
        }  
    }  
}  
The following output is generated by the above code example.  
The OLEDB Source Component  
OLEDB Source
