1.項目中引用log4net.dll
wcf項目中首先引用log4net.dll動態庫，如下圖：
2.根目錄中配置log4net.config
在wcf項目的根目錄下放置log4net.config配置文件，我這裏並將其配置爲（按自己需求更改配置）：
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<configSections>
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net" />
</configSections>

</configuration>
3.引用DotNet.Utilities.dll或新建錯誤日誌幫助類
注：DotNet.Utilities.dll是碼雲上一個開源.net開發工具類庫，項目地址https://gitee.com/kuiyu/dotnetcodes
using log4net;
using System;
using System.Diagnostics;
namespace DotNet.Utilities
{
public static class Log
{
public static void Debug(object message)
{
LogManager.GetLogger(DotNet.Utilities.Log.GetCurrentMethodFullName()).Debug(message);
}
public static void Debug(object message, Exception ex)
{
LogManager.GetLogger(DotNet.Utilities.Log.GetCurrentMethodFullName()).Debug(message, ex);
}
public static void Error(object message)
{
LogManager.GetLogger(DotNet.Utilities.Log.GetCurrentMethodFullName()).Error(message);
}
public static void Error(object message, Exception exception)
{
LogManager.GetLogger(DotNet.Utilities.Log.GetCurrentMethodFullName()).Error(message, exception);
}
public static void Info(object message)
{
LogManager.GetLogger(DotNet.Utilities.Log.GetCurrentMethodFullName()).Info(message);
}
public static void Info(object message, Exception ex)
{
LogManager.GetLogger(DotNet.Utilities.Log.GetCurrentMethodFullName()).Info(message, ex);
}
public static void Warn(object message)
{
LogManager.GetLogger(DotNet.Utilities.Log.GetCurrentMethodFullName()).Warn(message);
}
public static void Warn(object message, Exception ex)
{
LogManager.GetLogger(DotNet.Utilities.Log.GetCurrentMethodFullName()).Warn(message, ex);
}
private static string GetCurrentMethodFullName()
{
StackFrame frame;
string str;
string str1;
bool flag;
try
{
int num = 2;
StackTrace stackTrace = new StackTrace();
int length = stackTrace.GetFrames().Length;
do
{
int num1 = num;
num = num1 + 1;
frame = stackTrace.GetFrame(num1);
str = frame.GetMethod().DeclaringType.ToString();
flag = (!str.EndsWith("Exception") ? false : num < length);
}
while (flag);
string name = frame.GetMethod().Name;
str1 = string.Concat(str, ".", name);
}
catch
{
str1 = null;
}
return str1;
}
}
}
4.程序中打印日誌示例
使用第3步的幫助類，向log4net.config中配置的路徑文件下打印日誌信息，如下：
5.AssemblyInfo程序集配置log4net
打開AssemblyInfo.cs程序集，增加一行代碼：
[assembly: log4net.Config.XmlConfigurator(ConfigFile = "log4net.config", Watch = true)]
6.重寫ServiceHostFactory與ServiceHost
在解決方案的該wcf項目中，增加一個類文件，重寫ServiceHostFactory與ServiceHost（需添加引用System.ServiceModel與System.ServiceModel.Activation引用），如下：
using System;
using System.ServiceModel;
using System.ServiceModel.Activation;
namespace LookPictureService
{
public class CustomServiceHostFactory : ServiceHostFactory
{
protected override ServiceHost CreateServiceHost(
Type serviceType, Uri[] baseAddresses)
{
CustomServiceHost customServiceHost =
new CustomServiceHost(serviceType, baseAddresses);
return customServiceHost;
}
}
public class CustomServiceHost : ServiceHost
{
public CustomServiceHost(Type serviceType, params Uri[] baseAddresses)
: base(serviceType, baseAddresses)
{
log4net.Config.XmlConfigurator.Configure();
}
protected override void ApplyConfiguration()
{
base.ApplyConfiguration();
}
}
}
7.使用代碼配置控制檯寄宿程序
新建一個控制檯項目，添加對wcf服務項目的引用，使用代碼配置控制檯以寄宿wcf服務，如下：
using LookPictureService;
using System;
using System.ServiceModel;
using System.ServiceModel.Description;
namespace TestLookPictureService
{
class Program
{
static void Main(string[] args)
{
// Step 1: Create a URI to serve as the base address.
Uri baseAddress = new Uri("http://localhost:8734/Design_Time_Addresses/LookPictureService/CalculatorService/");
Uri baseAddress1 = new Uri("http://localhost:8734/Design_Time_Addresses/LookPictureService/LookPictureService/");
// Step 2: Create a ServiceHost instance.
ServiceHost selfHost = new CustomServiceHost(typeof(CalculatorService), baseAddress);
ServiceHost selfHost1 = new CustomServiceHost(typeof(LookPictureService.LookPictureService), baseAddress1);
try
{
//修改默認Binding
BasicHttpBinding binding = new BasicHttpBinding();
binding.MaxBufferSize = 2147483647;
binding.MaxReceivedMessageSize = 2147483647;
// Step 3: Add a service endpoint.
selfHost.AddServiceEndpoint(typeof(ICalculator), new BasicHttpBinding(), "CalculatorService");
selfHost1.AddServiceEndpoint(typeof(ILookPictureService), binding, "LookPictureService");//使用修改的的Binding
// Step 4: Enable metadata exchange.
ServiceMetadataBehavior smb = new ServiceMetadataBehavior();
ServiceMetadataBehavior smb1 = new ServiceMetadataBehavior();
smb.HttpGetEnabled = true;
smb1.HttpGetEnabled = true;
selfHost.Description.Behaviors.Add(smb);
selfHost1.Description.Behaviors.Add(smb1);
// Step 5: Start the service.
selfHost.Open();
selfHost1.Open();
Console.WriteLine("The service is ready.");
Console.WriteLine("The service1 is ready.");
// Close the ServiceHost to stop the service.
Console.WriteLine("Press <Enter> to terminate the service.");
Console.WriteLine("Press <Enter> to terminate the service1.");
Console.WriteLine();
Console.ReadLine();
selfHost.Close();
selfHost1.Close();
}
catch (CommunicationException ce)
{
Console.WriteLine("An exception occurred: {0}", ce.Message);
selfHost.Abort();
}
}
}
}
8.根據log4net.config的配置查看日誌
在控制檯寄宿程序的根目錄下，有配置的Log文件夾，查看日誌信息，如下：
