.net – Can you use reflection to find the name of the currently executing method

netreflection

Like the title says: Can reflection give you the name of the currently executing method.

I'm inclined to guess not, because of the Heisenberg problem. How do you call a method that will tell you the current method without changing what the current method is? But I'm hoping someone can prove me wrong there.

Update:

Part 2: Could this be used to look inside code for a property as well?
Part 3: What would the performance be like?

Final Result
I learned about MethodBase.GetCurrentMethod(). I also learned that not only can I create a stack trace, I can create only the exact frame I need if I want.

To use this inside a property, just take a .Substring(4) to remove the 'set_' or 'get_'.

For non-async methods one can use

System.Reflection.MethodBase.GetCurrentMethod().Name;

Please remember that for async methods it will return "MoveNext".

C# – How to use reflection to invoke a private method

Simply change your code to use the overloaded version of GetMethod that accepts BindingFlags:

MethodInfo dynMethod = this.GetType().GetMethod("Draw_" + itemType, 
    BindingFlags.NonPublic | BindingFlags.Instance);
dynMethod.Invoke(this, new object[] { methodParams });

Here's the BindingFlags enumeration documentation.

Java – How to invoke a Java method when given the method name as a string

Coding from the hip, it would be something like:

java.lang.reflect.Method method;
try {
  method = obj.getClass().getMethod(methodName, param1.class, param2.class, ..);
} catch (SecurityException e) { ... }
  catch (NoSuchMethodException e) { ... }

The parameters identify the very specific method you need (if there are several overloaded available, if the method has no arguments, only give methodName).

Then you invoke that method by calling

try {
  method.invoke(obj, arg1, arg2,...);
} catch (IllegalArgumentException e) { ... }
  catch (IllegalAccessException e) { ... }
  catch (InvocationTargetException e) { ... }

Again, leave out the arguments in .invoke, if you don't have any. But yeah. Read about Java Reflection
