c# - 企业库异常处理 6.0 XML 日志记录不写入文件

Question

我正在尝试设置 Enterprise Library Exception Handling 6.0，以使用 Enterprise Library Logging Application Block 中的 XmlExceptionFormatter 记录错误。我没有收到任何错误，我可以让日志记录自行工作。

这是我正在测试的控制台应用程序中的 App.config:

<?xml version="1.0" encoding="utf-8" ?>

    </exceptionPolicies>
  </exceptionHandling>

  <startup>
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
  </startup>
</configuration>

我的测试是:

class Program
{
    public static void Main(string[] args)
    {
        TestExceptionManager();

        Console.ReadLine();
    }

    private static void TestExceptionManager()
    {
        ExceptionManager exceptionManager = new ExceptionManager();
        exceptionManager.Process(MyExceptionCode, "Policy");
    }

    private static void MyExceptionCode()
    {
        throw new Exception("A basic Exception");
    }
}

有什么建议可以正确记录吗？

在版本 6 中你需要使用工厂方法，更新示例:

using Microsoft.Practices.EnterpriseLibrary.Common.Configuration;
using Microsoft.Practices.EnterpriseLibrary.ExceptionHandling;
using Microsoft.Practices.EnterpriseLibrary.Logging;
using System;

namespace ExceptionHandlingExamples
{
    class Program
    {
        public static void Main(string[] args)
        {
            try
            {
                TestExceptionManager();
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.ToString());
            }

            Console.ReadLine();
        }

        private static void TestExceptionManager()
        {
            IConfigurationSource config = ConfigurationSourceFactory.Create();
            ExceptionPolicyFactory factory = new ExceptionPolicyFactory(config);
            Logger.SetLogWriter(new LogWriterFactory().Create());

            ExceptionManager exceptionManager = factory.CreateManager();

            exceptionManager.Process(MyExceptionCode, "Policy");
        }

        private static void MyExceptionCode()
        {
            throw new Exception("A basic Exception");
        }
    }
}
