XPO使用了标准的System.Diagnostics的Trace Log机制,只需要在config文件中加入如下代码,即可在Debug时在输出窗口看到XPO生成的SQL语句。
Config
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.diagnostics>
<switches>
<add name="XPO" value="3" />
</switches>
</system.diagnostics>
</configuration>
<configuration>
<system.diagnostics>
<switches>
<add name="XPO" value="3" />
</switches>
</system.diagnostics>
</configuration>
也可以将其记录到日志文件:
Config
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.diagnostics>
<trace autoflush="true" indentsize="4">
<listeners>
<add name="LogFileTraceListener" type="System.Diagnostics.TextWriterTraceListener"
initializeData="trace.log" />
<remove name="Default" />
</listeners>
</trace>
<switches>
<add name="XPO" value="3" />
</switches>
</system.diagnostics>
</configuration>
<configuration>
<system.diagnostics>
<trace autoflush="true" indentsize="4">
<listeners>
<add name="LogFileTraceListener" type="System.Diagnostics.TextWriterTraceListener"
initializeData="trace.log" />
<remove name="Default" />
</listeners>
</trace>
<switches>
<add name="XPO" value="3" />
</switches>
</system.diagnostics>
</configuration>
因为采用.NET标准的Trace Log机制,我们也可以自己实现一个Log类:
MyTraceListener
using System;
namespace Test
{
public class MyTraceListener: System.Diagnostics.TraceListener
{
public MyTraceListener()
{
}
public MyTraceListener(string name)
: base(name)
{
}
public override void Write(string message)
{
throw new NotImplementedException();
}
public override void WriteLine(string message)
{
throw new NotImplementedException();
}
}
}
namespace Test
{
public class MyTraceListener: System.Diagnostics.TraceListener
{
public MyTraceListener()
{
}
public MyTraceListener(string name)
: base(name)
{
}
public override void Write(string message)
{
throw new NotImplementedException();
}
public override void WriteLine(string message)
{
throw new NotImplementedException();
}
}
}
然后在Config文件中做配置 :
Config
<system.diagnostics>
<trace autoflush="true" indentsize="4">
<listeners>
<!--注意命名空间和类名别写错-->
<add name="MyTraceListener" type="Test.MyTraceListener,Test"/>
<remove name="Default" />
</listeners>
</trace>
<switches>
<add name="XPO" value="3" />
</switches>
</system.diagnostics>
<trace autoflush="true" indentsize="4">
<listeners>
<!--注意命名空间和类名别写错-->
<add name="MyTraceListener" type="Test.MyTraceListener,Test"/>
<remove name="Default" />
</listeners>
</trace>
<switches>
<add name="XPO" value="3" />
</switches>
</system.diagnostics>
或者在程序的入口点加上:
// Remove the original default trace listener.
Trace.Listeners.RemoveAt(0);
// Create and add a new MyTraceListener.
Trace.Listeners.Add(new MyTraceListener());
Trace.Listeners.RemoveAt(0);
// Create and add a new MyTraceListener.
Trace.Listeners.Add(new MyTraceListener());
这样Log内容想记哪儿都可以随自己喜欢了,MyTraceListener的具体实现就不展开了。
