控制台托管的WCF服务不跟踪

时间:2011-11-04 04:18:22

标签: c# wcf servicehost

我编写了一份简单的服务合同(IServiceObject),然后实施了它(ServiceObject)。我将它托管在控制台应用程序中包含的ServiceHost对象中。在我的OperationContract方法中,我称之为Trace.WriteLine(...)。我也打电话给Console.WriteLine(...)。在控制台应用程序中,在Open() ServiceHost之前和之后,我致电Trace.WriteLine(...)Console.WriteLine(...)

跟踪设置为autoflush,并有2个侦听器(TextWriterTraceListenerConsoleTraceListener)。当控制台应用程序启动时,所有Trace和Console WriteLine()调用都将写入其各自的日志中。因此Trace调用将写入我的文本文件和控制台,Console调用将写入我的控制台。

当我的客户端应用程序(单独的应用程序)调用OperationContract方法时,控制台屏幕上只显示其中的Console.WriteLine(...)个调用。 Trace.WriteLine(...)调用不会写入控制台屏幕或文本文件。

当我(在OperationContract方法中)查询Trace统计数据时(使用Console.WriteLine(...)将它们输出到控制台屏幕)我被告知Trace中有2个侦听器(文本和控制台)并且autoflush已开启。

有谁知道为什么我对Trace.WriteLine(...)的调用只能在OperationContract方法中写入任何一个侦听器?我需要用一些特定的属性来装饰我的ServiceObject类吗?是否有某些设置我可能会在某处丢失?在我看来,跟踪是正确配置的,因为除了我的OperationContract方法之外,它可以在任何地方工作......

这似乎是个问题,我的共享库只包含我的OperationContract及其实现:

IServiceObject.cs

using System;
using System.Collections.Generic;
using System.Text;
using System.ServiceModel;
using System.Diagnostics;

namespace SuccessEHS.Dev.Shared
{
    [ServiceContract]
    public interface IServiceObject
    {
        [OperationContract]
        bool Test(string text);
    }
}

ServiceObject.cs

using System;
using System.Collections.Generic;
using System.Text;
using System.Diagnostics;
using System.ServiceModel;

namespace SuccessEHS.Dev.Shared
{
    public class ServiceObject : IServiceObject
    {
        public bool Test(string text)
        {
            Console.Write("Testing 1");
            Trace.Write("..2");
            Console.Write("..3");
            Trace.Write("..4");
            Console.WriteLine("..5");

            Console.WriteLine("CW: {0}", text);
            Trace.WriteLine(string.Format("TW: {0}", text));

            return true;
        }
    }
}

Shared.csproj(我怀疑是罪魁祸首但不确定原因):

我构建了一个新的服务器控制台应用程序来托管一个新的共享库和一个新的客户端控制台应用程序来连接它并且没有任何问题。当我将此项目作为共享库(上图)导入时,跟踪无法在ServiceObject.cs中找到工作。有什么新想法吗?

This article介绍了如何为WCF启用配置跟踪侦听器/源。有多个部分,如果你错过了其中一部分我希望跟踪不起作用。

您是否尝试过WCF Service Trace Viewer。看看这是否为您提供任何帮助。
