如何将值从一个线程传递到另一个线程 [英] How to pass a value from one thread to another thread

问题描述

我们现在必须并行运行线程，如何将一个线程中的值传递给另一个线程.请帮帮我.

We are having to thread running in parallel now how to pass a value from one thread to another thread.Please help me out.

推荐答案

线程间同步和传递数据的不同方案.使用最广泛的模式之一是使用数据队列，尤其是阻塞队列.通过阻塞，可以使预期数据线程与其他线程提供的数据可用性保持同步.它的一个有趣变体是使用委托实例，因此一个线程可以将整个方法与所有要在另一个线程上执行的必需参数(重要的是包括"this")一起传递.

这创建了一种类似于UI线程调用机制的机制(对于System.Windows.Forms和WPF使用System.Windows.Forms.Control.Invoke (BeginInvoke)或System.Windows.Threading.Dispatcher实现).但是-注意！ —此类调用仅可用于通过各自的UI库的UI线程；对于任意线程，开发人员可以创建类似的机制，我将在下面引用的文章中进行演示.

There can be many different scenarios of inter-thread synchronization and passing the data. One of the most widely used patterns is using data queues, in particular, blocking queues; the blocking enables synchronization of the thread expecting data with the availability of the data supplied form other thread(s). On interesting variant of it is using delegate instances, so one thread can pass the whole method with all required parameters (importantly, including "this") to be executed on another thread.

This creates a mechanism similar to the UI thread invocation mechanism (implemented for System.Windows.Forms and WPF with System.Windows.Forms.Control.Invoke (BeginInvoke) or System.Windows.Threading.Dispatcher). But — attention! — such invocation is only available for UI threads through respective UI libraries; for the arbitrary threads, the similar mechanism can be created by a developer, which I demonstrate in my article referenced below.

For further detail, please see my article complete with full source code and usage samples:
