How to instantiate a class in C#?
Use the new operator to instantiate a class in C#.
Let’s say our class is Line. Instantiation will create a new object as shown below −
Line line = new Line();
Using the object, you can now call the method −
line.setLength(6.0);
Let us see the example −
Example
using System; namespace LineApplication { class Line { private double length; // Length of a line public Line() { Console.WriteLine("Object is being created"); } public void setLength( double len ) { length = len; } public double getLength() { return length; } static void Main(string[] args) { Line line = new Line(); // set line length line.setLength(6.0); Console.WriteLine("Length of line : {0}", line.getLength()); } } }
Output
Object is being created Length of line : 6
