Пример

The following code example adds a task to a package then runs the package. The warnings collection is shown by creating a WarningEnumerator and displaying 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);
        }
    }
}

Imports System
Imports System.Collections.Generic
Imports System.Text
Imports Microsoft.SqlServer.Dts.Runtime
Imports Microsoft.SqlServer.Dts.Tasks.ExecuteSQLTask
 
Namespace Microsoft.SqlServer.SSIS.Samples
    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
