DtsWarnings.GetEnumerator 方法

定义

命名空间:

Microsoft.SqlServer.Dts.Runtime

程序集:

Microsoft.SqlServer.ManagedDTS.dll

返回用于遍历 WarningEnumerator 集合的 DtsWarnings。

public:
 Microsoft::SqlServer::Dts::Runtime::WarningEnumerator ^ GetEnumerator();

public Microsoft.SqlServer.Dts.Runtime.WarningEnumerator GetEnumerator ();

override this.GetEnumerator : unit -> Microsoft.SqlServer.Dts.Runtime.WarningEnumerator

Public Function GetEnumerator () As WarningEnumerator

返回

WarningEnumerator

一个 WarningEnumerator 枚举器。

示例

下面的代码示例将任务添加到包，然后运行包。 通过创建 WarningEnumerator 和显示每个警告说明来显示警告集合。

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  

示例输出：

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
