What are Access Modifiers?

Access modifiers are keywords which are used to define the scope / accessibility of class members. Access modifier keywords should be added in front of the variable or function to define its scope.

The following are the 4 access modifiers available in C# .Net

Private
Public
Protected
Internal

The following example contains a class which declared one variable based on each of the access modifiers.

class BaseClass

{

   private string strPrivateName;

   public string strPublicName;

   protected string strProtectedName;

   internal string strInternalName;

}
