如何在方法中调用BackgroundWorker.ReportProgress？ [英] How to call BackgroundWorker.ReportProgress in a method?

问题描述

有什么方法可以做这样的事情吗？

Hi, there is any way to do something like this?

public void mybw_DoWork(object sender, DoWorkEventArgs e){
...
while(...){
   ...
   mymetod();
   ....
}
....

}


public void mymetod() {
...
...
//Here i want to call mybw.ReportProgress, how can i do this?
...
...
}

我确定这是一个愚蠢的问题，但我不知道该怎么办：/

I'm sure this is a stupid question, but i dont know how to do :/

推荐答案

查看MSDN上的示例：

你必须投您的发件人参数类型为BackgroundWorker：

Have a look at the example on MSDN:

[^]

You have to cast your sender argument to type BackgroundWorker:

BackgroundWorker worker = sender as BackgroundWorker;

那么你可以把那个工人传给我作为一个论点。

Then you can pass that worker into mymethod as an argument.

public void mymetod(BackgroundWorker worker)
{
   worker.ReportProgress(...);
}

CodeProject上有一个很好的教程：[ ^ ]。



你会想要在BackGroundWorker的'DoWork EventHandler中的代码中显示'while循环...或其他导致多次迭代代码的其他内容。

There's a good tutorial here on CodeProject: [^].

You will want to locate the 'while loop ... or whatever else causes multiple iterations of exceuting code ... shown in your code in the BackGroundWorker's 'DoWork EventHandler.
