How to determine calling method and class name?
提问by Neurodefekt
I'm currently developing a application logging library using the built in TraceListener. This library will be used in many projects and should offer a simple interface where I only have to care about WHAT is going to be written in into the log file, but not HOW.
我目前正在使用内置的 TraceListener 开发应用程序日志库。这个库将在许多项目中使用，应该提供一个简单的界面，我只需要关心将要写入日志文件的内容，而不是如何写入。
By using the reflection namespace, I can figure out which application currently called a log function (retrieving execution assembly name), but I want also the name of the function and class that called the logging function.
通过使用反射命名空间，我可以找出当前调用日志函数的应用程序（检索执行程序集名称），但我还需要调用日志函数的函数和类的名称。
Let's say I have:
假设我有：
public static void LogInfo(string vLogText) {
Trace.WriteLine(
MethodInfo.GetCurrentMethod().Name
+ this.GetType().ToString() + vLogText);
}
When I call from another project (class: TestClass, method: TestMethod)
当我从另一个项目调用时（类：TestClass，方法：TestMethod）
Tracer.LogInfo("log this!")
I expect to see in the log:
我希望在日志中看到：
TestClass, TestMethod, log this!
But instead I got
但是我得到了
TracerClass, LogInfo, log this!

Try doing something like this:
尝试做这样的事情：
var mth = new StackTrace().GetFrame(1).GetMethod();
var cls = mth.ReflectedType.Name;
// where 1 illustrates how deep into the stack to reflect.
There are more elegant solutions in C# 5.0 >, however if you are using older frameworks, the above will help.
C# 5.0 > 中有更优雅的解决方案，但是如果您使用的是较旧的框架，以上内容会有所帮助。

You may just record the full stack trace instead of just the calling method using Environment.StackTrace. This may help you if you want to use the same logging structure to log exceptions.
您可以只记录完整的堆栈跟踪，而不仅仅是使用Environment.StackTrace. 如果您想使用相同的日志记录结构来记录异常，这可能会对您有所帮助。
