Ejemplos

En el ejemplo de código siguiente se agrega una tarea a un paquete y, a continuación, se ejecuta el paquete. La colección de advertencias se crea mediante la creación de un WarningEnumerator, que hereda de esta DtsEnumerator clase y muestra cada descripción de advertencia.

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

{  
    class Program  
    {  
        static void Main(string[] args)  
        {  
            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.FailPackageOnFailure = false;  
            package.FailParentOnFailure = false;  
            package.DelayValidation = true;  
            package.Execute();  

            Console.WriteLine("Package warnings count after running the package: {0}", package.Warnings.Count);  

            // 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);  
        }  
    }  
}
