C# : Data conversion : Explicit & Implicit Data Conversion |
|
Implicit Data conversion example (also read keyword implicit and explicit) | Explicit Conversion |
The data type conversion is an important aspect of any object oriented programming. | |
using System; //csc implicit_explicit.cs namespace try_imex { public class im_ex { public im_ex() { Console.WriteLine("Constructor Evoked");} ~im_ex() { Console.WriteLine("Destructor Evoked");} public double test_implicit(int xn, double xd) { int i = xn; double d = xd; // An implicit conversion, no data will be lost. Console.WriteLine("what is i : " + i + " And What is d : " + d); // since it is a value type data it will not change i in the above line // the line below will throw an error about i = d; Console.WriteLine("what is i again: " + i + " And What is d again: " + d); return(i + d); } //class im_ex ends } class test { public static void Main() { im_ex imex = new im_ex(); Console.WriteLine("Enter an Intger"); int nn = Int32.Parse(Console.ReadLine()); Console.WriteLine("Enter an Double"); double dd = Int64.Parse(Console.ReadLine()); //calling the method } } //namespace try_imex ends } |

Now remark // i =d ; using System; //csc implicit_explicit_1.cs namespace try_imex { public class im_ex { public im_ex() { Console.WriteLine("Constructor Evoked");} ~im_ex() { Console.WriteLine("Destructor Evoked");} public double test_implicit(int xn, double xd) { int i = xn; double d = xd; // An implicit conversion, no data will be lost. Console.WriteLine("what is i : " + i + " And What is d : " + d); // since it is a value type data it will not change i in the above line // the line below will throw an error about //i = d; Console.WriteLine("what is i again: " + i + " And What is d again: " + d); return(i + d); } //class im_ex ends } class test { public static void Main() { im_ex imex = new im_ex(); Console.WriteLine("Enter an Intger"); string str = Console.ReadLine(); int nn = Int32.Parse(str); Console.WriteLine("Enter an Double"); str = Console.ReadLine(); double dd = double.Parse(str); //calling the method imex.test_implicit(nn, dd); } } //namespace try_imex ends } |

Now convert int data to double implicitly |
