Today, I would like to share with you the relevant knowledge about how to use the Private 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.

Private access modifier

The Private access modifier allows a class to hide its member variables and functions from other functions and objects. Only functions in the same class can access its private members. Even an instance of a class cannot access its private members.

The following example illustrates this:

Using System

Namespace RectangleApplication

{

Class Rectangle

{

/ / member variable

Private double length

Private double width

Public void Acceptdetails ()

{

Console.WriteLine ("Please enter length:")

Length = Convert.ToDouble (Console.ReadLine ())

Console.WriteLine ("Please enter width:")

Width = Convert.ToDouble (Console.ReadLine ())

}

Public 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.Acceptdetails ()

R.Display ()

Console.ReadLine ()

}

}

}

When the above code is compiled and executed, it produces the following results:

Please enter length: 4.4 Please enter width: 3.3 length: 4.4 width: 3.3 area: 14.52

In the above example, the member variables length and width are declared as private, so they cannot be accessed by the function Main ().

The member functions AcceptDetails () and Display () can access these variables.

Because the member functions AcceptDetails () and Display () are declared as public, they can be accessed by Main () using an instance of the Rectangle class r.
