How to obtain the parameters of the previous method in the method called ?

Question

See more:

If I pass parameters to a "Method A" and within this method call another "Method B" is not passed parameters. As I can get the values of the parameters of the method of "A" in the "B " method.

---------------------------------------------------------------------------------

C#

public class A{

	public void Method_A(string name){
	
		var b = new B();
		
		b.Method_B();
	}
}

public class B{

	public void Method_B(){	
	/*
		see parameter values of Method_A	
	*/	
	}
}

Totally unclear. Please improve your question with relevant code fragment.

Still you did not provide any code fragment illustrating your question.

If i get it correctly, you can use reference variables. Have a look at it in Google.com

What is the reason you don't like/can pass a Parameter also to Method_B in class B?

The code is already done and I wanted a generic form of log errors

That's a terrible idea. I could write Method_C and call Method_B from it. How can you expect Method_B to be able to use whatever parameters Method_C has? Or would you want to somehow detect whether or not Method_B was called from Method_A and throw an execption if it wasn't?

Method_A would have to pass it's parameters to Method_B.

Have you considered having class A pass the equivalent of Method_B to class B as a delegate? Or maybe class B needs an event?

I'm trying to express your question in valid c# code:

C#

void MethodA(int param) {
   MethodB();
}

void MethodB() {
   // You cannot access MethodA's parameter here
}

Solution:
- Pass the parameter to MethodB (but that means modifying MethodB's signature):

C#

void MethodA(int param) {
   MethodB(param);
}

void MethodB(int param) {
   // Here you can access param's value
}

OR
- Use a global variable outside of your methods:

C#

int _param;

void MethodA(int param) {
   _param = param;
   MethodB();
}

void MethodB() {
   // Here you can access _param which has been initialized with MethodA's parameter
}
