What is the difference between implicit and explicit type conversion in C#?
The following is the difference between implicit and explicit type conversion −
Implicit Type Conversion
These conversions are performed by C# in a type-safe manner.
To understand the concept, let us implicitly convert int to long.
int val1 = 11000; int val2 = 35600; long sum; sum = val1 + val2;
Above, we have two integer variable and when we sum it in a long variable, it won’t show an error. Since the compiler does the implicit conversion on its own.
Let us print the values now.
Example
using System; using System.IO; namespace Demo { class Program { static void Main(string[] args) { int val1 =34567; int val2 =56743; long sum; sum = val1 + val2; Console.WriteLine("Sum= " + sum); Console.ReadLine(); } } }
Explicit Type Conversion
These conversions are done explicitly by users using the pre-defined functions.
Let us see an example to typecast double to int −
Example
using System; namespace Program { class Demo { static void Main(string[] args) { double d = 1234.89; int i; // cast double to int. i = (int)d; Console.WriteLine(i); Console.ReadKey(); } } }
