.net 寻找丑陋的多线程的标准替代方案
我一直在尝试不同的异步处理数据的方法。我有一段代码可以在图像处理应用程序中完成这样的任务,但对我来说似乎很尴尬。我正在寻找符合当前标准的建议,或遵循的编码约定:.net 寻找丑陋的多线程的标准替代方案,.net,vb.net,multithreading,.net,Vb.net,Multithreading,我一直在尝试不同的异步处理数据的方法。我有一段代码可以在图像处理应用程序中完成这样的任务,但对我来说似乎很尴尬。我正在寻找符合当前标准的建议,或遵循的编码约定: ' this code is run on a background thread Dim lockThreadCounter As New Object() Dim runningThreadCounter As Integer = 0 Dim decrementCounterCallback As New AsyncCallback

我考虑过并行。Foreach,但由于任务具有不同的代理示意图,因此无法提出使用它的解决方案。您可以使用该类启动您的工作,并等待它们完成
这样就不需要“运行线程计数器”,因为每个任务都可以作为一个组存储和等待
这看起来像(一旦删除回调):
这正是我想要的。非常感谢。
Dim widths1 = Task.Factory.StartNew(Sub() widthsSlow())
Dim widths2 = Task.Factory.StartNew(Sub() widthsFast())
Dim bruteForce1 = Task.Factory.StartNew(Sub() numberOfSamples(pixelsSlow))
Dim bruteForce2 = Task.Factory.StartNew(Sub() numberOfSamples(pixelsFast))
' Wait for all to complete without the loop
Task.WaitAll(widths1, widths2, bruteForce1, bruteForce2)
