英文:
System.AccessViolationException at InitializeComponent()
问题
我注意到你提供了一些代码和XAML，但你没有提出具体的问题或翻译请求。请问你需要针对这些代码或XAML的哪部分进行翻译或需要什么样的帮助？
英文:
I'm working on a UWP app, and it keeps crashing at the InitializeComponent(); call with the error message: System.AccessViolationException: 'Attempted to read or write protected memory. This is often an indication that other memory is corrupt.'
Here's my code for this class:
using System.Collections.Generic;
using System.Linq;
using Windows.UI.Xaml;
using Windows.UI.Xaml.Controls;
using Windows.UI.Xaml.Media;
namespace esheets_trafalgareng
{
public sealed partial class Tasks : Page
{
public static List<Button> Buttons { get; set; }
public static Button SelectedButton;
public Tasks()
{
InitializeComponent();
}
private void Page_Loaded(object sender, RoutedEventArgs e)
{
Buttons = new List<Button>();
foreach (Button button in secondaryContainer.Children.OfType<Button>())
{
if (button.Name == "myTasks") SelectedButton = button;
Buttons.Add(button);
}
if (SelectedButton != null) SelectedButton.isPressed = true;
UpdateTheme();
}
public void TaskListChanged(Button button)
{
UpdateTheme();
}
private void UpdateTheme()
{
if (Theme.IsLight()) SetLightTheme();
else SetDarkTheme();
}
private void SetLightTheme()
{
//Theme.UseImmersiveDarkMode(this.handle, false);
primaryContainer.Background = new SolidColorBrush(Theme.LightMain);
primaryContainer.PaneBackground = new SolidColorBrush(Theme.LightSide);
}
private void SetDarkTheme()
{
//Theme.UseImmersiveDarkMode(this.handle, true);
primaryContainer.Background = new SolidColorBrush(Theme.DarkMain);
primaryContainer.PaneBackground = new SolidColorBrush(Theme.DarkSide);
}
internal void AddButton(Button button)
{
secondaryContainer.Children.Add(button);
Buttons.Add(button);
}
}
}
And my XAML code:
<Page

mc:Ignorable="d"
Background="{ThemeResource ApplicationPageBackgroundThemeBrush}" Loaded="Page_Loaded">
<Grid>
<SplitView x:Name="primaryContainer" Grid.RowSpan="2" IsPaneOpen="True">
<SplitView.Pane>
<StackPanel x:Name="secondaryContainer">

</StackPanel>
</SplitView.Pane>
</SplitView>
</Grid>
</Page>
The Button and PersonalButton components are custom components and I've put their code below:

Here's 2 other classes that I use, in case they are needed:

{
get
{

else if (Tasks.SelectedButton.Name == "assignedToMe") return Color.FromArgb(0, 213, 241, 229);
else return Color.FromArgb(0, 153, 51, 102);
}
}
internal static readonly Color DarkSide = Color.FromArgb(0, 34, 34, 34);
internal static readonly Color DarkTask = Color.FromArgb(0, 42, 42, 42);
internal static readonly Color DarkButtonHover = Color.FromArgb(0, 50, 50, 50);
internal static readonly Color DarkMain = Color.FromArgb(0, 28, 28, 28);
internal static bool IsLight()
{

{
return true;
}
else if (Options.Theme == Dark)
{
return false;
}
else
{

}
else

}
}
}
internal static bool UsingLightTheme()
{

string uiTheme = DefaultTheme.GetColorValue(UIColorType.Background).ToString();
return uiTheme == "#FFFFFFFF";
}
[DllImport("dwmapi.dll")]
private static extern int DwmSetWindowAttribute(IntPtr hwnd, int attr, ref int attrValue, int attrSize);
private const int DWMWA_USE_IMMERSIVE_DARK_MODE_BEFORE_20H1 = 19;
private const int DWMWA_USE_IMMERSIVE_DARK_MODE = 20;
internal static bool UseImmersiveDarkMode(IntPtr handle, bool enabled)
{

}
return false;
}
private static bool IsWindows10OrGreater(int build = -1)
{

}
}
}
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace esheets_trafalgareng
{
internal class Options
{
public static int Theme { get; set; } = 3;
public static bool IsLoggedIn { get; set; }
}
}

问题是我将组件定义为C#类而不是用户控件。如果其他人遇到此问题，请确保为您的组件有一个.xaml文件和一个.cs.xaml文件！
英文:
After some research, I figured out that the problem was that I was defining my components as C# classes rather than User Controls. If anyone else comes across this issue, make sure you have a .xaml and a .cs.xaml file for your components!
