DTSBreakpointHitTest Enumeration

Enumerates the values for the hit count types. This class works with the BreakpointTarget class.

Public Enumeration DTSBreakpointHitTest

public enum DTSBreakpointHitTest

public enum class DTSBreakpointHitTest

public enum DTSBreakpointHitTest

public enum DTSBreakpointHitTest

Members

Member name	Description
Always	Execution is always suspended when the breakpoint is hit.
Equal	Execution is suspended when the number of times the breakpoint has occurred is equal to the hit count.
Expression	Execution is suspended when the expression changes.
GreaterOrEqual	Execution is suspended when the number of times the breakpoint has occurred is equal to or greater than the hit count.
Multiple	Execution is suspended when a multiple of the hit count occurs.

Osservazioni

To add flexibility and power to a breakpoint, you can modify the behavior of a breakpoint by configuring the breakpoint hit count, which specifies the number of times a breakpoint occurs before the run-time engine is suspended, and the hit count type, which contains an expression that specifies when the breakpoint is hit. This value is used in the HitTest property.

Esempio

The following code example modifies the default value of a BreakpointTarget using this enumeration.

using Microsoft.SqlServer.Dts.Runtime;

namespace Microsoft.SqlServer.SSIS.Samples
{
    class Program
    {
        static void Main(string[] args)
        {
            Package pkg = new Package();
            TaskHost taskHost = (TaskHost)pkg.Executables.Add("STOCK:FileSystemTask");
            BreakpointTargets bptargets = pkg.GetBreakpointTargets(taskHost, false);

            // Get the first breakpoint in the collection.
            BreakpointTargetEnumerator myEnumerator = bptargets.GetEnumerator();
            myEnumerator.MoveNext();
            BreakpointTarget bptFirstOne = myEnumerator.Current;

            // Display the initial values.
            Console.WriteLine("Description              {0}", bptFirstOne.Description);
            Console.WriteLine("Enabled?                 {0}", bptFirstOne.Enabled);
            Console.WriteLine("HitTest                  {0}", bptFirstOne.HitTest);
            Console.WriteLine("ID                       {0}", bptFirstOne.ID);
            Console.WriteLine("--------------------------------------------");

            // Modify the default value of HitTest.
            myEnumerator.Reset();

            bptFirstOne = myEnumerator.Current;
            bptFirstOne.HitTest = DTSBreakpointHitTest.Equal;

            // Display the values again, including the new HitTest.
            Console.WriteLine("Description              {0}", bptFirstOne.Description);
            Console.WriteLine("Enabled?                 {0}", bptFirstOne.Enabled);

            Console.WriteLine("ID                       {0}", bptFirstOne.ID);
        }
    }
}
