Exemples

L’exemple de code suivant ajoute une tâche à un package, puis exécute le package. La collection d’avertissements est créée en créant un WarningEnumerator, qui hérite de cette DtsEnumerator classe et affiche chaque description d’avertissement.

using Microsoft.SqlServer.Dts.Runtime;

        {  
            Package package = new Package();  
            Console.WriteLine("Package warnings count before running: {0}", package.Warnings.Count);  

            TaskHost taskH2 = (TaskHost)package.Executables.Add("STOCK:SendMailTask");  
            taskH2.FailPackageOnFailure = false;  
            taskH2.FailParentOnFailure = false;  
            Console.WriteLine("SendMailTask: {0}", taskH2.ID);  

            // Test that warnings were successfully added to the collection.  
            package.MaximumErrorCount = 100;

            package.FailParentOnFailure = false;

            package.Execute();

            // Create the enumerator.  
            WarningEnumerator myEnumerator = package.Warnings.GetEnumerator();  
            Console.WriteLine("The collection contains the following values:");  
            int i = 0;  
            while ((myEnumerator.MoveNext()) && (myEnumerator.Current != null))  
                Console.WriteLine("[{0}] {1}", i++, myEnumerator.Current.Description);  
        }

Exemple de sortie :

Nombre d’avertissements de package avant d’exécuter : 0

SendMailTask : {34CAEFF9-64BF-401D-B646-C88B705DB971}

Nombre d’avertissements de package après l’exécution du package : 2

La collection contient les valeurs suivantes :

[0] L’adresse de la ligne From n’est pas correctement formée. Il manque un @ ou il n’est pas valide.

[1] L’objet est vide
