[Source] .NET/C# attributes CallerMemberName, CallerFilePath, CallerLineNumber

Three Attributes were introduced in .Net 4.5: CallerMemberName, CallerFilePath, and CallerLineNumber. With the help of the compiler, you can get the name of the calling function (to be precise, it should be a member), the call file and the call line number.

Documentation:https://docs.microsoft.com/en-us ... membernameattribute

You can also use StackTrace and StackFrame objects to get them, but with this feature, we can get them more conveniently.

StackTrace: Represents a stack trace, which is an ordered collection of one or more stack frames.

StackFrame: Provides information about the StackFrame (a function call in the call stack that represents the current thread).

Previously, I used AOP to get the caller's method name through StackTrace, and the code is as follows:


Using the feature, the test code is as follows:

Get the current method name from an asynchronous function?

The hyperlink login is visible.

C# 5 adds caller information properties, which may give you more of what you're looking for. Note that these insert the appropriate information at compile time into the calling site, rather than using runtime information. More limited functionality (obviously you don't get the full call stack), but much faster.
