我正在使用Azure表存储作为存储机制.我可以将视图模型中的异常从视图模型中写入Azure表，但当我try 向App.cs上的未处理异常添加处理程序时，异常会记录在Debug Output窗口中，但不会存储在Azure表中.
这是我的Program.cs分:
public static class MauiProgram
{
public static MauiApp CreateMauiApp()
{
var builder = MauiApp.CreateBuilder();
builder
.UseMauiApp<App>()
.ConfigureFonts(fonts =>
{
fonts.AddFont("OpenSans-Regular.ttf", "OpenSansRegular");
fonts.AddFont("OpenSans-Semibold.ttf", "OpenSansSemibold");
fonts.AddFont("SF-Pro-Text-Bold.otf", "SFProTextBold");
fonts.AddFont("SF-Pro-Text-Regular.otf", "SFProTextRegular");
fonts.AddFont("materialdesignicons-webfont.ttf", "MaterialDesignIcons");
});
builder.UseMauiApp<App>()
.UseMauiCommunityToolkit()
.RegisterDataServices()
.RegisterViewModels()
.RegisterViews();
builder.Logging.AddSerilog();
var storageConnectionString = "MY_CONNECTION_STRING";
var tableName = "logs";
Log.Logger = new LoggerConfiguration()
.WriteTo.AzureTableStorage(connectionString: storageConnectionString, storageTableName: tableName)
.WriteTo.Debug()
.CreateLogger();
return builder.Build();
}
}
这是我的App.cs:
public partial class App : Application
{
private readonly ILogger<App>_logger;
public App(ILogger<App> logger)
{
_logger = logger;
InitializeComponent();
AppDomain.CurrentDomain.UnhandledException += HandleUnhandledException;
MainPage = new AppShell();
}
private void HandleUnhandledException(object sender, UnhandledExceptionEventArgs e)
{
var exception = (Exception)e.ExceptionObject;
_logger.LogCritical(exception, exception.Message);
}
}
}
这是我要实现日志(log)记录的一个视图模型:
public class OnboardingViewModel : BaseViewModel
{
private ILogger<OnboardingViewModel> _logger;
public OnboardingViewModel(ILogger<OnboardingViewModel> logger)
{
_logger = logger;
}
private void OnSkipOnboardingCommand()
{
try
{
throw new Exception("Oops! Something went wrong.");
}
catch (Exception e)
{
_logger.LogError(e, e.Message);
}
}
}
当我try 这样做时，异常显示在输出窗口上，并保存到Azure表中:
但是，如果我将OnSkipOnboardCommand更改为:
private void OnSkipOnboardingCommand()
{
throw new Exception("Oops! Unhandled Exception.");
}
我在App.cs号的HandleUnhandledException号收到了例外.异常仅记录到输出窗口中:
[0:] [07:38:43 FTL] Oops! Unhandled Exception.
System.Exception: Oops! Unhandled Exception.

然而，这一例外在Azure存储上不会持续存在.这只发生在App.cs上的HandleUnhandledException方法的异常情况下.
异常被写入到输出窗口而不是Azure表的事实真的让我感到困惑.
你知道为什么会发生这种情况吗，或者我如何使用Serilog获取未处理的异常并将它们存储在Azure表中？我应该对我的代码进行一些更改吗？
