我编写了一个简单的服务合同 ( IServiceObject
),然后实施它 ( ServiceObject
)。我将它托管在一个ServiceHost
包含在控制台应用程序中的对象中。在OperationContract
我调用的一种方法中Trace.WriteLine(...)
。我也叫Console.WriteLine(...)
。在控制台应用程序中,在 I 之前和之后Open()
,ServiceHost
我调用Trace.WriteLine(...)
and Console.WriteLine(...)
。
Trace 设置为 autoflush,并且有 2 个侦听器(TextWriterTraceListener
和ConsoleTraceListener
)。当控制台应用程序启动时,所有 Trace 和 ConsoleWriteLine()
调用都会写入各自的日志。所以 Trace 调用将写入我的文本文件和我的控制台,而 Console 调用将写入我的控制台。
当我的客户端应用程序(一个单独的应用程序)调用该OperationContract
方法时,只有其中的Console.WriteLine(...)
调用会显示在控制台屏幕上。Trace.WriteLine(...)
调用不会写入控制台屏幕或文本文件。
当我(从OperationContract
方法中)查询 Trace stats(使用 将它们输出到控制台屏幕Console.WriteLine(...)
)时,我被告知 Trace(文本和控制台)中有 2 个侦听器,并且自动刷新已打开。
有谁知道为什么我的调用Trace.WriteLine(...)
无法仅从OperationContract
方法内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
班级吗?是否有一些我可能在某处丢失的设置?在我看来,跟踪配置正确,因为它可以在任何地方工作,除了我的OperationContract
方法......
这似乎是个问题,我的共享库只包含我的 OperationContract 及其实现:
服务对象.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);
}
}
服务对象.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,但不知道为什么):

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。然后,当我将此项目作为共享库(上图)导入时,在 ServiceObject.cs 中发现的跟踪失败。有什么新想法吗?
