The public access modifier in C# means that a class member (method, property, field) can be accessed from any other code, without scope restrictions. In other words, such members are accessible everywhere the class itself is visible.

For example:

public class Person
{
    public string Name; // accessible from anywhere
}

var p = new Person();
p.Name = "Ivan"; // allowed, since Name is public

Using public makes the class interface open for interaction with other parts of the program.
