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();
}
}
}
