In this article We will see that how to define
function Overloading and how to use Function Overloading in VB.NET.
In method overloading, multiple method having
the same name but different type of argument. sometimes
our
reqirement needs us to be able to create more function with same names this
allows programer to provide easiness to the user by allowing user to use single
name for different purposes.
For example:
Public Overloads
Sub area(ByVal
r)
Public Overloads
Sub area(ByVal
length, ByVal width)
In the above example there are two method which
has the same name but use for different purpose one define the area of circle
and other define the area of rectangle. Both method have the different
parameter.
The following code define the Function
overloading:
Imports
System
Module
Module1
Class overload
Dim r As
Double
Public Overloads
Sub area(ByVal
r) // define the function name area
Console.Write("Area
of the Circle :")
Console.WriteLine(1 / 3 * 3.14 * r * r * r)
End Sub
Dim length As
Integer
Dim width As
Integer
Public Overloads
Sub area(ByVal
length, ByVal width) // define the function area
Console.Write("
Area of the Rectangle :")
Console.WriteLine(length * width)
End Sub
End Class
Sub Main()
Dim r As
New overload()
// creating object of the class overload
r.area(3.1)
r.area(4, 5)
End Sub
End
Module
OUTPUT:
Conclusion:
Hope this article would have
helped you in understanding Method Overloading in VB.NET.
