DTSBreakpointHitTest 枚举

定义

命名空间:

Microsoft.SqlServer.Dts.Runtime

程序集:

Microsoft.SqlServer.ManagedDTS.dll

枚举命中计数类型的数值。 这个职业是和课程一起 BreakpointTarget 工作的。

public enum class DTSBreakpointHitTest

public enum DTSBreakpointHitTest

type DTSBreakpointHitTest = 

Public Enum DTSBreakpointHitTest

继承

Enum

DTSBreakpointHitTest

字段

名称	值	说明
Always	0	断点命中时始终挂起执行。
GreaterOrEqual	1	断点发生的次数等于或大于命中计数时挂起执行。
Equal	2	断点发生的次数等于命中计数时挂起执行。
Multiple	3	断点发生的次数为命中计数的倍数时挂起执行。
Expression	4	当表达式发生变化时，执行会被暂停。

示例

以下代码示例利用该枚举修改了 的 BreakpointTarget 默认值。

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

namespace Microsoft.SqlServer.SSIS.Samples

        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("HitTest                  {0}", bptFirstOne.HitTest);

            Console.WriteLine("--------------------------------------------");  

            // Modify the default value of HitTest.  
            myEnumerator.Reset();  
            myEnumerator.MoveNext();  
            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("HitTest                  {0}", bptFirstOne.HitTest);  
            Console.WriteLine("ID                       {0}", bptFirstOne.ID);  
        }  
    }  
}

是否启用？ 假

HitTest 始终

注解

为了增强断点的灵活性和功能，可以通过配置断点命中计数（指定断点在运行时引擎暂停前出现的次数）和命中计数类型（包含断点被击中时的表达式）来修改断点的行为。 该价值用于房 HitTest 产。
