我应该在设计中的哪里放置项目或应用程序范围的 TraceSwitch？
我正在尝试使用 System.Diagnostics 提供的一些日志记录功能来增强我的程序。 由于我的解决方案由多个项目组成，因此我想为整个应用程序创建一个开关，并为每个项目创建一个开关。
现在的问题是，我怎样才能实现这一点以及我应该将开关定义放在哪里？
从应用程序范围的开关开始，由于按照我的理解，C# 中没有全局变量之类的东西，我怎样才能实现这一点呢？
在每个类中放置
static TraceSwitch ApplicationSwitch = new TraceSwitch("Application", "Enables logging in the whole application.");
一次会解决这个问题，还是会创建与类一样多的开关，每个开关都具有相同的名称？ （我的猜测是后者）
或者我应该将初始化放在一个单独的类中
static class GlobalSwitch
{
static TraceSwitch Application = new TraceSwitch("Application", "Enables logging in the whole application.");
}
，并从像这样的每个其他类中引用它
public OtherClass
{
static TraceSwitch Application = GlobalSwitch.Application;
}
这将解决整个项目有1个开关的问题，但这是一个好的做法吗？
关于应用程序范围的切换，我必须在每个其他项目中引用包含 GlobalSwitch 类的项目，如果可能的话，我希望避免这种情况。
关于如何以智能方式完成此操作的一些线索将非常感激。
I'm trying to enhance my program with some logging functionality provided by System.Diagnostics. As my Solution consists of several projects, I wanted to create a switch for the whole application and one for every project.
Now the question is, how can I achieve this and where should I put the switch definition?
Starting with the application wide switch, since there is no such thing as global variables in C# as I understood it, how could I achieve this?
Will putting
static TraceSwitch ApplicationSwitch = new TraceSwitch("Application", "Enables logging in the whole application.");
once in every class solve this or would this rather create as much switches as there are classes, each with the same name? (my guess is the latter)
Or should I put the initialization once in a separate class
static class GlobalSwitch
{
static TraceSwitch Application = new TraceSwitch("Application", "Enables logging in the whole application.");
}
and reference to it from every other class like this
public OtherClass
{
static TraceSwitch Application = GlobalSwitch.Application;
}
This would solve having 1 switch for a whole project, but is this a good practice?
Concerning the application wide switch, I would have to reference the project containing the GlobalSwitch class in every other project, which I would like to avoid if possible.
Some clues as to how this can be done the smart way would be very appreciated.

我通常将跟踪开关（和日志函数）包装到中央日志记录程序集中，向开关公开静态接口以及静态日志方法，这些方法将调用正在使用的底层日志功能（通常是 Trace.Write 函数）。
I usually wrap trace switches (and log functions) into a central logging assembly, exposing a static interface to the switch(es) and also static log methods that will call the underlying log functionality in use (usually Trace.Write-functions).
