Question

是否可以通过编程方式打开登录到本地硬盘驱动器？

（例如：登录到文件C：\ temp \ Rabbit.log）

（（当然，目录和名称也会改变）

换句话说，我希望能够在创建Rabbit MQ连接时打开（或关闭）登录记录。

背景：从我的应用程序中的引用中使用RabbitMQ

在Visual Studio中，通过NuGet右键单击“参考”

add reference : RabbitMQ.Client.dll (v4.0.30319)

这是我的代码，它运行Rabbit MQ的客户端。（消息处理代码已被删除）

using RabbitMQ.Client;
using RabbitMQ.Client.Events;
using RabbitMQ.Client.MessagePatterns;

private void Internal_Run(CancellationToken cancelToken)
{
    var connectionFactory = new ConnectionFactory();

    // I know this is wrong... but this is what I would ***like*** to do:
    // connectionFactory.IsLogging = true;
    // connectionFactory.LogPathAndFile = "C:\\Temp\\Rabbit.log";


    connectionFactory.HostName = "My Host";
    connectionFactory.UserName = "My userName";
    connectionFactory.Password = "My password";
    string QueueName = "My unique queue name";

    try
    {
        using (IConnection connection = connectionFactory.CreateConnection())
        {
            using (IModel model = connection.CreateModel())
            {
                //Note declare the queue here, as well. Because we might start the receiver before the sender, 
                // we want to make sure the queue exists before we try to consume messages from it
                model.QueueDeclare(queue: QueueName, durable: true, exclusive: false, autoDelete: false, arguments: null);
                var subscription = new Subscription(model, QueueName, false);

                int milisecondTimeOut_RabbitMQ = 500;
                while (true)
                {
                    BasicDeliverEventArgs basicDeliveryEventArgs;
                    if (subscription.Next(milisecondTimeOut_RabbitMQ, out basicDeliveryEventArgs))
                    {
                        if (basicDeliveryEventArgs == null)
                        {
                            continue;
                        }
                        if (basicDeliveryEventArgs.Body.Length == 0)
                        {
                            continue;
                        }

                        string messageContent = Encoding.UTF8.GetString(basicDeliveryEventArgs.Body);

                        subscription.Ack(basicDeliveryEventArgs);  // send the ACK back to queue to let Rabbit know I processed the message
                    }

                    if (cancelToken.IsCancellationRequested)
                    {
                        break;
                    }
                }
            }
        }
    }
    catch (OperationCanceledException oce)
    {
        // this is an expected cancellation - program shutting down
    }
    catch (Exception ex)
    {
        throw new Exception(ex.Message);
    }
}

必须创建自定义NLOG配置文件。这是一个示例：

<nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd"

  throwExceptions="false">

<variable name="AppName" value="ManagerService" />
<variable name="LogDir" value="Logs" />

<variable name="logFormat_File" value="[${longdate}][${logger}] 
[${message}${onexception:${newline}EXCEPTION\: ${exception:format=ToString}}]"/>
<variable name="logFormat_Console" value="${longdate} | ${logger} | 
${level:uppercase=true} | ${message}"/>
<variable name="logFormat_Debugger" value="[${logger}] '${message}'"/>
