Examples
The following code sample uses Contains method to determine if a pipeline component with the name "Merge" is in the collection. The method returns a Boolean.
using System;
using System.Collections.Generic;
using System.Text;
using Microsoft.SqlServer.Dts.Runtime;
namespace TaskInfos_Item
{
class Program
{
static void Main(string[] args)
{
Application app = new Application();
PipelineComponentInfos pInfos = app.PipelineComponentInfos;
// Search the collection by name.
if (pInfos.Contains("Merge"))
Console.WriteLine("The collection contains {0} pipeline component", pInfos[0].Name);
else
Console.WriteLine("The collection does not contain {0} pipeline component", pInfos[0].Name);
}
}
}
Imports System
Imports System.Collections.Generic
Imports System.Text
Imports Microsoft.SqlServer.Dts.Runtime
Namespace TaskInfos_Item
Class Program
Shared Sub Main(ByVal args() As String)
Dim app As Application = New Application()
Dim pInfos As PipelineComponentInfos = app.PipelineComponentInfos
' Search the collection by name.
If pInfos.Contains("Merge") Then
Console.WriteLine("The collection contains {0} pipeline component", pInfos(0).Name)
Else
Console.WriteLine("The collection does not contain {0} pipeline component", pInfos(0).Name)
End If
End Sub
End Class
End Namespace
Sample Output:
The collection contains Merge pipeline component
