值结构未在 WinRT 中初始化

Question

无论出于何种原因，Windows 运行时组件中定义的 value struct 的初始化值在应用程序 (C#) 中被忽略。

CX/C++:

namespace RuntimeComponent1
{
    public value struct Foo {
        bool flag1 = true;
        bool flag2 = false;
    };
}

C#

public sealed partial class MainPage : Page
{
    public MainPage()
    {
        this.InitializeComponent();

        var settings = new RuntimeComponent1.Foo();
        Debug.WriteLine(settings.flag1); // Output: False
        Debug.WriteLine(settings.flag2); // Output: False
    }
}

请注意 flag1 应该是 True 而不是 False。为什么？ !

Thank you for reporting this issue. The next release of the Visual C++ Compiler Toolset will issue an error when a member of a value class has a default member initializer.
