[英]Cannot assign to 'method' because it is a 'method group
I can't run my code because there is a error saying: 我无法运行我的代码,因为有一个错误说:
Cannot assign to 'OnNewLand' because it is a 'method group
无法分配给'OnNewLand',因为它是'方法组
This is strange because I have used the same structure as my other methods and there were no problem with them. 这很奇怪,因为我使用了与我的其他方法相同的结构,并且它们没有问题。 Here is my code.
这是我的代码。
private void CreateNewFlight()
{
string flightCode = ReadFlightCode();
//Create the new bidder
if (!string.IsNullOrEmpty(flightCode))
{
FlightWindow frm = new FlightWindow(Flightcode.Text);
frm.Show();
//Subscribe to the publisher's new bid and quit bid events
frm.NewStart += OnNewStartClick;
frm.NewChangeRoute += OnNewChangeRoute;
frm.OnNewLand += OnNewLand; <----Here is the error <-------
}
}
Cannot assign to 'OnNewLand' because it is a 'method group
无法分配给'OnNewLand',因为它是'方法组
My other window: 我的另一个窗口:
public event EventHandler<Start> NewStart;
public event EventHandler<ChangeRoute> NewChangeRoute;
public event EventHandler<Land> NewLand;
private void btnStart_Click(object sender, RoutedEventArgs e)
{
Start startinfo = new Start(this.Title);
OnNewStart(startinfo); //Raise event
btnLand.IsEnabled = true;
Routetxt.IsEnabled = true;
changebtn.IsEnabled = true;
btnStart.IsEnabled = false;
}
private void changebtn_Click(object sender, RoutedEventArgs e)
{
ChangeRoute changeinfo = new ChangeRoute(this.Title, Routetxt.Text);
OnNewChangeRoute(changeinfo); //Raise event
}
private void btnLand_Click(object sender, RoutedEventArgs e)
{
Land landinfo = new Land(this.Title);
OnNewLand(landinfo); //Raise event
}
//Raise Event
public void OnNewStart(Start e)
{
if (NewStart != null)
NewStart(this, e);
}
public void OnNewChangeRoute(ChangeRoute e)
{
if (NewChangeRoute != null)
NewChangeRoute(this, e);
}
public void OnNewLand(Land e)
{
if (NewLand != null)
NewLand(this, e);
}
