In this code snippet, we will learn how to use access modifiers in C#.
Access modifiers are used to define the access level of types and members. The following access modifiers are available: public, private, protected, internal, protected internal, private protected.
- public members are accessible to everyone.
- private members are only accessible to code inside their class.
- protected members can only be accessed from their class or any derived(child) class.
- internal members can be accessed by any code inside the same assembly.
Let’s see how to use access modifiers in the code example below.
Code:
using System;
namespace AccessModifiers
{
class Program
{
static void Main(string[] args)
{
//Types of access modifiers
//Public members are accessible to everyone.
//Private members are only accessible to code inside their class.
//There are a few more access modifiers such as protected, internal, ...
//Protected members can only be accessed from their class or any derived(child) class.
//Internal members can be accessed by any code inside the same assembly.
MyClass MC = new MyClass();
//Can be accessed outside of the class as it's marked as public.
MC.MyPublicProperty = 10;
//Cannot be accessed outside of the class as it's marked as private.
//MC.MyPrivateProperty = 10;
//This method can be accessed ouotside it's class.
MC.MyPublicMethod();
//This method can't be accessed outside of it's class.
//MC.MyPrivateMethod();
Console.ReadLine();
}
}
class MyClass
{
public int MyPublicProperty { get; set; }
private int MyPrivateProperty { get; set; }
public void MyPublicMethod()
{
Console.WriteLine("From MyPublicMethod()");
//This method can only be called from inside its class.
MyPrivateMethod();
}
private void MyPrivateMethod()
{
Console.WriteLine("From myPrivateMethod()");
}
}
} Resulting output:
