c# - Windows Phone 7 事件调用？

Question

我正在尝试使用 Visual Studio C# 处理事件，就像我处理 Windows 窗体一样，例如:

在我的 Windows Phone 7 上，我的代码如下所示:

//ASDF.CS CLASS  

public delegate void SignedOn(string Screenname);

public event SignedOn SO;

public void dataIncoming(string packet)
{
     switch (packet)
 {
    case 0:
        if (SO != null)
                                    SO(m_Screenname);
        break;
}
}

//MainWindow.xaml.cs

m_A.SignedOn += new ASDF.SignedOn(m_A_LoggedIn);


void m_OSC_LoggedIn(string Screenname, string FormattedSN, string Email)
    {
        //Works all the way to this sub then the code in here don't get ran because there is no invoke with WP7

        MessageBox.Show("hello!");
}

我的 Windows 窗体代码看起来像这样工作:

//ASDF.CS CLASS  

public delegate void SignedOn(string Screenname);

public event SignedOn SO;

public void dataIncoming(string packet)
{
     switch (packet)
 {
    case 0:
        if (SO != null)
                                    SO(m_Screenname);
        break;
}
}

//MainWindow.cs

m_A.SignedOn += new ASDF.SignedOn(m_A_LoggedIn);


void m_OSC_LoggedIn(string Screenname, string FormattedSN, string Email)
    {
         this.Invoke(new MethodInvoker(delegate
        {
            MessageBox.Show("hello!");
    }));
}

那么，有没有其他方法可以让调用与 Windows Phone 7 一起工作？

还有其他方法可以让它在 WP7 上运行吗？

谢谢

尝试使用:

void m_OSC_LoggedIn(string Screenname, string FormattedSN, string Email)
{

        Dispatcher.BeginInvoke(() =>
        {
              MessageBox.Show("hello!");
        });
}
