Global and Local Variables in C#

In this post, you will learn how to work with global and local variables so that you can use that same knowledge and thus evolve.

• global variables are all those that are defined outside a function (in the “root” of our code) and have a global scope;
• local variables are all those that are defined inside a function;
• in short, not all variables are accessible from all places in our code.

using System;

namespace Base {
  class GlobalAndLocalVariables {
    string access = "Global";

    public void Run() {
      ChangeAccess();
      Console.WriteLine($"Access from outside the function: {access}");
    }

    public void ChangeAccess() {
      string access = "Local";
      Console.WriteLine($"Access inside the function: {access}");
    }
  }
}

/*
  Access inside the function: Local
  Access from outside the function: Global
*/

Happy coding!
