get() & set() property

Public Class Hello
Private _sample As String
Public Property Sample() As String
Get
'1
Return _sample
End Get
Set(ByVal Value As String)
'2
_sample = Value
End Set
End Property

Public Sub DoSomething()
Me.Sample = "SampleText" '2
MessageBox.Show(Me.Sample) '1
End Sub
End Class

We know that data encapsulation and hiding are the two fundamental characteristics of any object oriented programming language. We create private variables/members in a class. In order to set and get the values in these variables we use public functions normally. In addition to that C# provides a built in mechanism called properties using these we can set and get the values of the private member variables.

Syntax of Properties:

<acces_modifier> <return_type> <property_name>
{
get
{
}
set
{
}
}


Example :

class MyClass
{
private int x; //Private variable
public int X //Property used to set and get the values of x.
{
get
{
return x;
}
set
{
x = value;
}
}
}
class MyClient
{
public static void Main()
{
MyClass mc = new MyClass();
mc.X = 10;
int xVal = mc.X;
Console.WriteLine(xVal);//Displays 10
}
}
