WPF C＃BackgroundWorker用于方法[重复]

Question

我有一个类 Population，其中包含一个 Evolve 方法，该方法迭代直到 int 变量generationNumber

/////////////
MainWindow.cs
/////////////

void m_oWorker_ProgressChanged(object sender, ProgressChangedEventArgs e)
{
    Population p=new Population()
    ...
    p.Evolve();
    //Where to call ReportProgress? I cannot acces local variable generationsNumber that is declared in Evolve method
} 

Answer 1

在BackgroundWorker 实例上调用ReportProgress()。
