Winforms log4net.Config.XmlConfigurator.Configure（）给出-“；FileNotFoundException跨越了本机/托管边界“；

这只是我第二次尝试使用log4net。这是一个Windows窗体应用程序，我以为一切都设置好了，但我没有创建任何日志文件。我发现了一些建议，建议需要显式地让它读取app.config文件，因此我在这里添加了log4net.config.XmlConfigurator.Configure（）：

public partial class GridForm : Form
{
    public static readonly ILog log = LogManager.GetLogger(typeof(GridForm));

    public GridForm()
    {
        InitializeComponent();
                                          // Initialize log4net (make him read the app.config file)
        log4net.Config.XmlConfigurator.Configure();     // this gives the exception 
    }

我对如何引用log4net.dll有点不确定

• 我在解决方案中有两个项目——CBMI.Common（类库项目）和CBMI.WinFormsUI（表单项目）（启动表单）
• 我将log4net.dll复制到了CBMI.Common的bin目录（不是bin\debug文件夹）
• 然后在我的表单项目中添加了一个指向该位置的引用：CBMI.Common\bin

这样编译不会出错。我想应该没问题，但是

我无法从引发的异常和显示的消息中确定要执行的操作：

我的修复方法是将
[assembly:log4net.Config.XmlConfigurator（Watch=true）]
插入assemblyinfo.cs
