An example of using progress bars in winform

Source: Internet
Author: User

In the winform program, the UI thread is responsible for interface-related work.

There are many ways to use progress bars in winform. You can directly create a new thread execution time-consuming method, or use a thread pool.

For example:

// Use the thread pool to asynchronously execute the longtime method without blocking the UI thread system. Threading. threadpool. queueuserworkitem (_ =>{ dosomething ();}

If you want to use a progress bar, you can simulate the progress operation. In a loop,

// Use the thread pool to asynchronously execute the longtime method without blocking the UI thread system. threading. threadpool. queueuserworkitem (_ => {dosomething (); // simulate the update progress bar updateprogress (total, I );} /// <summary> /// simulate the update progress bar /// </Summary> /// <Param name = "Total"> total progress </param> /// <Param name = "value"> current progress </param> private void updateprogress (INT total, int value) {This. begininvoke (new action () => {This. progressbar1.minimum = 0; this. progressbar1.maximum = total; this. progressbar1.value = value ;}));}
