如何发送更多的参数在C＃BackgroundWorker的进展更改事件 [英] How to send more arguments in C# backgroundworker progressed changed event

问题描述

我了解我们如何可以传递一个变量（progresspercentage）为progresschanged功能，像这样。

I understand how we can pass one variable(progresspercentage) to "progresschanged" function , like so.

backgroundWorker1.ProgressChanged += new ProgressChangedEventHandler(backgroundWorker1_ProgressChanged);

...

...

worker.ReportProgress(pc);

...

...

private void backgroundWorker1_ProgressChanged(object sender,
ProgressChangedEventArgs e)
{
   this.progressBar1.Value = e.ProgressPercentage;
}

不过，我想通过更多的变量这一功能，一些事情，如：

But I want to pass more variables to this function, some thing like:

worker.ReportProgress(pc,username,score);

...

...

private void backgroundWorker1_ProgressChanged(object sender,
ProgressChangedEventArgs e)
{
   this.progressBar1.Value = e.ProgressPercentage;
   this.currentUser.Value = e.UserName;  //as string
   this.score.Value = e.UserScore;  //as int
}

对不起我是新的C＃中，能有人给我。一个例子

sorry I'm new to c#, could someone give me an example.

推荐答案

后台工作部件的ReportProgress方法重载通过率和对象类型的状态值：

The ReportProgress method of background worker component is overloaded to pass percentage and an object typed state value:

public void ReportProgress(int percentProgress, Object userState)

在您的使用要求，您可以连接UserName和用炭分离得分，所以通过userState参数中的多个值;当它被升高拆分它们ProgressChanged（）事件内。您还可以创建基于类的使用值填充它，并使用输入参数userState对象传递小产权。

In your usage requirement you can concatenate the UserName and Score with a char separator, and so pass the multiple values inside the userState parameter; and split them inside the ProgressChanged() event when it is raised. You can also create a small property based class- fill it with values and pass using the userState object typed parameter.
