示例

以下代码示例生成一个 Package，即继承自 DtsContainer的类。 该书 Package 展示了若干继承财产的使用。

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

namespace Microsoft.SqlServer.SSIS.Samples  
{  
    class Program  
    {  
        static void Main(string[] args)  
        {  
            Application app = new Application();  
            Package pkg = new Package();  

            // Package name must be assigned.  
            pkg.Name = "My DtsContainer inheritance test package";  

            // Display the values that manually assigned.  
            Console.WriteLine("Package Name: {0}", pkg.Name);  

            // Packages are assigned the following default values when created.  
            Console.WriteLine("Package ID:           {0}", pkg.ID);  
            Console.WriteLine("FailPackageOnFailure: {0}", pkg.FailPackageOnFailure);  
            Console.WriteLine("FailParentOnFailure:  {0}", pkg.FailParentOnFailure);  
            Console.WriteLine("Locale ID:            {0}", pkg.LocaleID);  
            Console.WriteLine("Is DefaultLocaleID?   {0}", pkg.IsDefaultLocaleID);  
            Console.WriteLine("Isolation Level:      {0}", pkg.IsolationLevel);  
            Console.WriteLine("LoggingMode:          {0}", pkg.LoggingMode);  
            Console.WriteLine("MaximumErrorCount:    {0}", pkg.MaximumErrorCount);  
            Console.WriteLine("TransactionOption:    {0}", pkg.TransactionOption);  
        }  
    }  
}  

Imports System  
Imports System.Collections.Generic  
Imports System.Text  
Imports Microsoft.SqlServer.Dts.Runtime  

Namespace Microsoft.SqlServer.SSIS.Samples  
    Class Program  
        Shared  Sub Main(ByVal args() As String)  
            Dim app As Application =  New Application()   
            Dim pkg As Package =  New Package()   

            ' Package name must be assigned.  
            pkg.Name = "My DtsContainer inheritance test package"  

            ' Display the values that manually assigned.  
            Console.WriteLine("Package Name: {0}", pkg.Name)  

            ' Packages are assigned the following default values when created.  
            Console.WriteLine("Package ID:           {0}", pkg.ID)  
            Console.WriteLine("FailPackageOnFailure: {0}", pkg.FailPackageOnFailure)  
            Console.WriteLine("FailParentOnFailure:  {0}", pkg.FailParentOnFailure)  
            Console.WriteLine("Locale ID:            {0}", pkg.LocaleID)  
            Console.WriteLine("Is DefaultLocaleID?   {0}", pkg.IsDefaultLocaleID)  
            Console.WriteLine("Isolation Level:      {0}", pkg.IsolationLevel)  
            Console.WriteLine("LoggingMode:          {0}", pkg.LoggingMode)  
            Console.WriteLine("MaximumErrorCount:    {0}", pkg.MaximumErrorCount)  
            Console.WriteLine("TransactionOption:    {0}", pkg.TransactionOption)  
        End Sub  
    End Class  
End Namespace  

示例输出：

包名：我的 DtsContainer 继承测试包
