C# create a simple class and create object in main
In this example, we create a simple class, and create its object in main function:
namespace ConsoleApplication1 { class Test { public int a; public int b; } class Program { static void Main(string[] args) { int first = 20; int second = 30; Console.WriteLine(first + " " + second); first = second; first = 1000; Console.WriteLine(first + " " + second); Test t = new Test(); t.a = 10; t.b = 20; Console.WriteLine(t.a + " " + t.b); Test t1 = t; t1.a = 100; t1.b = 200; Console.WriteLine(t1.a + " " + t1.b); Console.WriteLine(t.a + " " + t.b); Test t3 = new Test(); t3.a = 111; t3.b = 222; Console.WriteLine(t3.a + " " + t3.b); } } }
