Exemples
The following code example adds a task to a package then runs the package. The warnings collection is created by creating a WarningEnumerator, which inherits from this DtsEnumerator class, and displays each warning description.
using System;
using System.Collections.Generic;
using System.Text;
using Microsoft.SqlServer.Dts.Runtime;
using Microsoft.SqlServer.Dts.Tasks.ExecuteSQLTask;
namespace Microsoft.SqlServer.SSIS.Samples
{
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);
}
}
}

Class Program
Shared Sub Main(ByVal args() As String)
Dim package As Package = New Package()
Console.WriteLine("Package warnings count before running: {0}", package.Warnings.Count)
Dim taskH2 As TaskHost = CType(package.Executables.Add("STOCK:SendMailTask"), TaskHost)
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.
Dim myEnumerator As WarningEnumerator = package.Warnings.GetEnumerator()
Console.WriteLine("The collection contains the following values:")
Dim i As Integer = 0
While (myEnumerator.MoveNext()) &&(myEnumerator.Current <> Nothing)
Console.WriteLine("[{0}] {1}",i = Console.WriteLine("[{0}] {1}",i + 1
End While
End Sub
End Class
End Namespace
Sample Output:
Package warnings count before running: 0
SendMailTask: {34CAEFF9-64BF-401D-B646-C88B705DB971}
Package warnings count after running the package: 2
The collection contains the following values:
[0] The address in the From line is not formed correctly. It is missing an @ or it is not valid.
[1] Subject is empty
