小编Mak*_*iek的帖子

是否可以使这些代码有效？:

    private List<Type> Models = new List<Type>()
    {
        typeof(LineModel), typeof(LineDirectionModel), typeof(BusStopTimeModel), typeof(BusStopNameModel)
    };

    foreach (Type model in Models) // in code of my method
    {
        Connection.CreateTable<model>(); // error: 'model' is a variable but is used like a type
    }

提前致谢

我正在学习WP编码,我遇到了无法解决的问题:/

try
 {
    NavigationService.Navigate(new Uri("/edit.xaml", UriKind.Relative));
 }
 catch (Exception ex)
 {
     MessageBox.Show(ex.Message.ToString(),"Error!",MessageBoxButton.OK);
 }

edit.xaml与MainPage.xaml位于同一目录中

它抛出"NullReferenceException"
