Postsharp不会记录跟踪级别

Question

我喜欢在跟踪级别上记录一些Postsharp消息。不幸的是，这个级别的日志没有输出。所有其他级别都在运作。与控制台或NLog后端相同的行为或当我从其他类登录时。

如何启用跟踪级别？

App.xaml.cs：

[Log(AttributeExclude = true)]
public partial class App
{
    private static readonly LogSource LogSource = LogSources.Default.ForCurrentType().WithLevels(LogLevel.Trace, LogLevel.Error);

    protected override void OnStartup(StartupEventArgs e)
    {
        LoggingServices.DefaultBackend = new PostSharp.Patterns.Diagnostics.Backends.Console.ConsoleLoggingBackend();
        LogSource.Debug.Write(Formatted("Debug"));      // prints "Debug"
        LogSource.Trace.Write(Formatted("Trace"));      // prints nothing
        LogSource.Default.Write(Formatted("Default"));  // prints nothing
        LogSource.Trace.IsEnabled                       // is false
        ..

GlobalAspect.cs

using PostSharp.Patterns.Diagnostics;
using PostSharp.Extensibility;

[assembly: Log(AttributePriority = 1, AttributeTargetMemberAttributes = MulticastAttributes.Protected | MulticastAttributes.Internal | MulticastAttributes.Public)]
[assembly: Log(AttributePriority = 2, AttributeExclude = true, AttributeTargetMembers = "get_*" )]

Answer 1

LogLevel.Trace是PostSharp诊断库中最低的日志记录级别。默认情况下，日志后端的详细程度设置为LogLevel.Debug，因此将忽略所有跟踪消息。您可以自定义日志记录后端的详细程度，如下例所示：

LoggingServices.DefaultBackend.DefaultVerbosity.SetMinimalLevel( LogLevel.Trace );
