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.

Esempio

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.

            TaskHost taskHost = (TaskHost)pkg.Executables.Add("STOCK:FileSystemTask");
            BreakpointTargets bptargets = pkg.GetBreakpointTargets(taskHost, false);
            foreach (BreakpointTarget bpt in bptargets)
