Значение свойства
A Boolean indicating if the code is to break when an expression changes. true indicates that the package is to break; false indicates that the package will not break.
Пример
The following code example retrieves the breakpoint target collection from the package and iterates through the breakpoints, displaying the properties for each breakpoint, including the BreakOnExpressionChange.

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

{
Package pkg = new Package();
TaskHost taskHost = (TaskHost)pkg.Executables.Add("STOCK:FileSystemTask");
BreakpointTargets bptargets = pkg.GetBreakpointTargets(taskHost, false);
foreach (BreakpointTarget bpt in bptargets)
{
Console.WriteLine("BreakOnExpressionChange? {0}", bpt.BreakOnExpressionChange.ToString());
Console.WriteLine("Description {0}", bpt.Description);
Console.WriteLine("Enabled? {0}", bpt.Enabled);
Console.WriteLine("HitCount {0}", bpt.HitCount);
Console.WriteLine("HitTarget {0}", bpt.HitTarget);
Console.WriteLine("HitTest {0}", bpt.HitTest);
Console.WriteLine("ID {0}", bpt.ID);
Console.WriteLine("Owner {0}", bpt.Owner);
