Ejemplos
En el ejemplo de código siguiente se crea una tarea Enviar correo y se agrega a un paquete. No todas las propiedades necesarias de la tarea Enviar correo se establecen, por lo que cuando se ejecuta el paquete, hay errores y advertencias en las DtsErrors colecciones y DtsWarnings . El Contains método se usa para ver si se puede acceder a las colecciones mediante la DtsWarnings[index]
sintaxis y, si es así, obtiene algunas propiedades con esa sintaxis.

Comentarios
Si la llamada al Contains método devuelve true
, puede tener acceso al elemento especificado en la colección mediante la sintaxis DtsWarning[index]
. Si el método Contains devuelve false
, esta propiedad producirá una excepción. En C#, esta propiedad es el indizador para la clase DtsWarnings.
