Executables.Contains(Object) Méthode

Définition

Espace de noms:

Microsoft.SqlServer.Dts.Runtime

Assembly:

Microsoft.SqlServer.ManagedDTS.dll

Indique si les éléments de la collection sont accessibles en utilisant l'index en tant que paramètre.

public:
 bool Contains(System::Object ^ index);

public bool Contains (object index);

member this.Contains : obj -> bool

Public Function Contains (index As Object) As Boolean

Paramètres

index

Object

Index de l'objet Executable.

Retours

Boolean

true si vous pouvez récupérer un élément à l’aide des exécutables de syntaxe[index]; false si l’indexation ne peut pas être utilisée pour récupérer des éléments de la Executables collection.

Exemples

L’exemple de code suivant ajoute la tâche d’insertion en bloc en tant qu’exécutable, puis utilise Contains pour vérifier l’existence d’au moins un exécutable dans le package.

using System;  
using System.Collections.Generic;  
using System.Text;  
using Microsoft.SqlServer.Dts.Runtime;  

namespace Executables_API  
{  
        class Program  
        {  
        static void Main(string[] args)  
        {  
            Package pkg = new Package();  
            Executable exec = pkg.Executables.Add("STOCK:BulkInsertTask");  

            // Obtain the collection.  
            Executables pgkExecs = pkg.Executables;  
            foreach (Executable eachExec in pgkExecs)  
            {  
                TaskHost th = exec as TaskHost;  
                Console.WriteLine("Executable creation name is: {0}", th.CreationName);  
            }  

            // Show use of Contains.  
            if (pgkExecs.Contains(0))  
            {  
                Console.WriteLine("Contains returned true");  
            }
