How to get method parameter in an array?

Question

Imagine in a class you got this Method:

float Do(int a_,string b_){}

I'm trying to do something like this:

float Do(int a_, string b_)
{
  var params = GetParamsListOfCurrentMethod(); //params is an array that contains (a_ and b_)
}

Can someone help ?

Why should I want to do thet ?

Imagine you got an Interface:

public Interface ITrucMuch
{
 float Do(int a_,string b_);
 // And much more fct
}

And a lot of classes implementing that interface

And a special class that also implement interface:

public class MasterTrucMuch : ITrucMuch
{
  public floatDo(int a_, string b_) 
  {
    ITrucMuch tm = Factory.GetOptimizedTrucMuch(); // This'll return an optimized trucMuch based on some state
    if(tm != null)
    {
      return tm.Do(a_,b_);
    }
    else
    {
      logSomeInfo(...);
    }

    //do the fallback method
  }

As the interface constains a lot of method and as the first lien of all method are always the same (checking if there is a better interface that the current instance and if so call the same method on the instance) I try to make a method of it.

Thx

You could do something like this:

var parameters = MethodBase.GetCurrentMethod().GetParameters();
foreach (ParameterInfo parameter in parameters)
{
    //..
}

Have a look at the ParameterInfo class.
