VB.NET并行与分布式编程(六)-线程与内核同步[7]

VB.NET并行与分布式编程(6)-线程与内核同步[7]

我们继续扩展刚才的话题，再次使用WaitAny完成一个简单的任务，求100以内阶乘之和

?

完成这个任务我们先来解决几个问题

1、如何将线程计算结果传出来，参数可以传入，而且只能传入一个，如何传入多个参数，并输出多个参数？

1）最经典的方法是定义一个类，这个类存放了传入的参数和传出的参数

?
?以上代码有几个重点要分析一下
1）VB.NET类的属性定义
? Public Class CalculateIfno
??????? Private _threadevent As AutoResetEvent
??????? Private _result As Long
??????? Public Property threadevent As AutoResetEvent
??????????? Get
??????????????? Return _threadevent
??????????? End Get
??????????? Set(ByVal value As AutoResetEvent)
??????????????? _threadevent = value
??????????? End Set
??????? End Property
??????? Public Property result As Long
??????????? Get
??????????????? Return _result
??????????? End Get
??????????? Set(ByVal value As Long)
??????????????? _result = value
??????????? End Set
??????? End Property
??? End Class?
?
上述类定义中
? Public Property threadevent As AutoResetEvent
??????????? Get
??????????????? Return _threadevent
??????????? End Get
??????????? Set(ByVal value As AutoResetEvent)
??????????????? _threadevent = value
??????????? End Set
??????? End Property
上段代码定义了一个属性，可以理解为
?
运行结果如下：
