Примеры
The following code example creates a Package, which is a class that inherits from DtsContainer. The Package shows the use of several inherited properties.
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);
}
