C# variable scoping not consistent?

Question

C# is quite nit-picking when it comes to variable scoping. How is it possible that it accepts this code:

class Program
{
    int x = 0;

    void foo()
    {         


        

Answer 1

Thats normal.

In constructors I often use the same.

public Person(string name) {
  this.name = name;
}

Else it would be not possible to declare method parameters which are named like member variables.
