[英]Adding console appender to a windows form in log4net
Is it possible to add a console to a form based C# application ? 是否可以将控制台添加到基于表单的C#应用程序中? Currently when I do something like
目前,当我做类似的事情
Console.WriteLine("testing");
It appears in output window of the VS2010. 它出现在VS2010的输出窗口中。 I want to know if its possible to attach a console to my windows form application.So that the output appears in the console.
我想知道是否可以将控制台附加到我的Windows窗体应用程序。以便输出出现在控制台中。
EDIT: Looks like my first question was a bit misleading and it did not exactly specify what I wanted to accomplish. 编辑:看起来我的第一个问题有点误导,它没有确切说明我想要完成的工作。 I just added a console to my application using
我刚刚使用将控制台添加到我的应用程序中
[DllImport("kernel32")]
static extern int AllocConsole();
However what I really want is the output of log4net console appender to be displayed in that console which is not happening. 但是,我真正想要的是log4net控制台附加程序的输出,该输出不会在该控制台中显示。 The xml for my appender is
我的appender的xml是
<appender name="ColoredConsoleAppender" type="log4net.Appender.ColoredConsoleAppender">
<mapping>
<level value="INFO" />
<foreColor value="White" />
<backColor value="Red, HighIntensity" />
</mapping>
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%class %date - %message %newline" />
</layout>
</appender>
now when I go like 现在,当我像
log.info("Some log");
It still does not display it in the newly added console window. 它仍然不会在新添加的控制台窗口中显示它。 Any suggestions on how i could do that ?
关于我该怎么做的任何建议?
Just to throw it out there, be sure that you AllocConsole()
before you load your log4net configuration. 只是将其丢到那里, 在加载log4net配置之前 ,请确保您已使用
AllocConsole()
。 I tried doing something similar to what your question asks, and had the same problem before moving my call to AllocConsole
. 在将呼叫移至
AllocConsole
之前,我尝试过执行与您的问题类似的操作,并且遇到了相同的问题。 Once I moved it, log4net automatically wrote to the console that I allocated. 移动它后,log4net会自动写入我分配的控制台。
Essentially ... (and remember to do all your regular error checking not included here) ... 本质上是...(并且请记住进行所有常规错误检查,此处未包括)...
using System;
using System.Runtime.InteropServices;
using System.Windows.Forms;
namespace SampleApp
{
class Program
{
[DllImport("kernel32.dll", SetLastError=true, CallingConvention=CallingConvention.Winapi)]
[return: MarshalAs(UnmanagedType.Bool)]
private static extern bool AllocConsole();
[DllImport("kernel32.dll", SetLastError=true, CallingConvention=CallingConvention.Winapi)]
[return: MarshalAs(UnmanagedType.Bool)]
private static extern bool FreeConsole();
[STAThread]
private static void Main(string[] args)
{
// (1) Make sure we have a console to use.
Program.AllocConsole();
try {
// (2) Tell log4net to configure itself according to our app.config data.
log4net.Config.XmlConfigurator.Configure();
// (3) Usual WinForms startup code here.
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new SampleApp.Form1());
} catch ( Exception ) {
// WAT!
}
// (4) Remember to release the console before we exit.
Program.FreeConsole();
}
}
}
Not 100% sure why it makes a difference as to when the console is allocated, but this did fix the problem for me. 不能100%确定为什么分配控制台的时间有所不同,但这确实为我解决了问题。
只需使您的项目成为控制台应用程序,然后从控制台应用程序创建/显示表单即可,而不是相反。
