Question

I have an application in mind, but I am not sure how to do this. Say I have some publically accessible method in a DLL file that takes no parameters. Is it possible for this method to know what called it? Can it tell if it were called from a static or instantiated context? From a specific class? What can a method know about how it’s being called?

Answer 1

You can get caller information from a stack trace:

StackTrace stackTrace = new StackTrace();
MethodBase methodBase = stackTrace.GetFrame(1).GetMethod();

It is possible for this method to know what called it:

string typeName = methodBase.DeclaringType.Name;
string methodName = methodBase.Name;

It can tell if it were called from a static or instantiated context:

bool isStaticCall = methodBase.IsStatic

From a specific class:

bool isGeneric = methodBase.DeclaringType.IsGenericType;
