Пример

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
