使用ManualResetEvent在内部等待

Question

I have an operation via While that i want to Freeze:

    do
    {
        ManualResetEvent.Reset(); // Here i want to wait

        // Here i am doing my stuff...
    }

    while (some boolean value);
}

My ManualResetEvent :

private static ManualResetEvent _manualResetEvent;

public static ManualResetEvent ManualResetEvent
{
    get { return _manualResetEvent; }
    set { _manualResetEvent = value; }
}

ManualResetEvent = new ManualResetEvent(false);

In some point in my code via Button i just want to freeze my operation:

private void btnPause_Click(object sender, RoutedEventArgs e)
{
    ManualResetEvent.WaitOne();
}

Is this the right way to do that ?

Answer 1

You have your two functions backwards. The loop you want to wait needs to use the .WaitOne() . Also, if you want it to run at the start you need to initialize the reset event to true

init

private static ManualResetEvent _manualResetEvent;

public static ManualResetEvent ManualResetEvent
{
    get { return _manualResetEvent; }
    set { _manualResetEvent = value; }
}

ManualResetEvent = new ManualResetEvent(true); //Set it to true to let it run at the start.

loop

    do
    {
        ManualResetEvent.WaitOne(); // Here i want to wait

        // Here i am doing my stuff...
    }

    while (some boolean value);
}

elsewhere

private void btnPause_Click(object sender, RoutedEventArgs e)
{
    ManualResetEvent.Reset();
}
private void btnUnPause_Click(object sender, RoutedEventArgs e)
{
    ManualResetEvent.Set();
}
