Exemples

L’exemple de code suivant crée une tâche Envoyer un courrier et l’ajoute à un package. Toutes les propriétés requises de la tâche Envoyer un courrier ne sont pas définies. Par conséquent, lorsque le package s’exécute, il existe des erreurs et des avertissements dans les collections et DtsWarnings les DtsErrors erreurs. La Contains méthode est utilisée pour voir si les collections sont accessibles à l’aide de la syntaxe et, le cas échéant, obtient certaines propriétés à l’aide DtsWarnings[index] de cette syntaxe.

Exemple de sortie :

SendMailTask: {12ADD307-23DA-42C9-A4B2-E360DEFD7563}

The first warning subcomponent is: Send Mail Task

The first warning subcomponent is: Send Mail Task

The first error description is: SMTP Server not specified

The first error description is: SMTP Server not specified

Remarques

Si l’appel à la Contains méthode retourne true, vous pouvez accéder à l’élément spécifié dans la collection à l’aide de la syntaxe DtsWarning[index]. Si la méthode Contains retourne false, cette propriété lèvera une exception. En C#, cette propriété est l'indexeur correspondant à la classe DtsWarnings.
