为什么Visual Studio会给我这种预期的错误类型

Question

I'm Developing windows phone 8.1 application when i want to start emulator Give me this error "Type expected" line 27 this is the line of code:

statusBar.BackgroundColor = new ((SolidColorBrush)Windows.UI.Xaml.Application.Current.Resources["PhoneAccentBrush"]);

`

Answer 1

Error is clear, you are not telling the type name:

statusBar.BackgroundColor = new (...);
                         -------^

Now, you've got a SolidColorBrush (after casting) but you're trying to get a Color . Fortunately, SolidColorBrush has a Color property which is what I suspect you want:

var brush = (SolidColorBrush) Application.Current.Resources["PhoneAccentBrush"];
statusBar.BackgroundColor = brush.Color;

Answer 2

You're trying to use the new operator, which requires a type, like this:

variable = new SomeType(constructorArguments);

You've got new and then a cast.

I suspect you just want the cast, without new :

// With a using directive for Windows.UI.Xaml...
statusBar.BackgroundColor = (SolidColorBrush) Application.Current.Resources["PhoneAccentBrush"];
