The public keyword is an access modifier for types and type members. Public access is the most permissive access level. There are no restrictions on accessing public members.
For a comparison of public with the other access modifiers, see Accessibility Levels.
In the following example, two classes are declared, MyClass1
and MyClass2
. The public members x and y of the MyClass1
are accessed directly from MyClass2
.
// Public access using System; class MyClass1 { public int x; public int y; } class MyClass2 { public static void Main() { MyClass1 mC = new MyClass1(); // Direct access to public members: mC.x = 10; mC.y = 15; Console.WriteLine("x = {0}, y = {1}", mC.x, mC.y); } }
x = 10, y = 15
If you change the public access level to private or protected, you will get the error message:
'MyClass1.y' is inaccessible due to its protection level.
