How to use the Internal access modifier of C #
Today, I would like to share with you the relevant knowledge about how to use the Internal access modifier in C#. The content is detailed and the logic is clear. I believe most people still know too much about this knowledge, so share this article for your reference. I hope you can get something after reading this article. Let's take a look.
Internal access modifier
The Internal access specifier allows a class to expose its member variables and member functions to other functions and objects in the current program. In other words, any member with the internal access modifier can be accessed by any class or method within the application defined by that member.
The following example illustrates this:
Using System
Namespace RectangleApplication
{
Class Rectangle
{
/ / member variable
Internal double length
Internal double width
Double GetArea ()
{
Return length * width
}
Public void Display ()
{
Console.WriteLine ("length: {0}", length)
Console.WriteLine ("width: {0}", width)
Console.WriteLine ("area: {0}", GetArea ())
}
} / / end class Rectangle
Class ExecuteRectangle
{
Static void Main (string [] args)
{
Rectangle r = new Rectangle ()
R.length = 4.5
R.width = 3.5
R.Display ()
Console.ReadLine ()
}
}
}
When the above code is compiled and executed, it produces the following results:
Length: 4.5 width: 3.5 area: 15.75
In the above example, notice that the member function GetArea () is declared without any access modifiers. If no access modifier is specified, the default access modifier for class members, which is private, is used.
