Introduction
Dynamic is a new keyword , which is
include in c# 4.0 version in 2010. Dynamic keyword manage by the Dynamic
Language Runtime (DLR), which work as a Common Language Runtime (CLR).
Dynamic variable not define as type, because dynamic variable manage
by the Dynamic Language Runtime (DLR). Dynamic variable is
declared as having type dynamic, operations on these value are not done or
verified at compile time, but instead happen entirely at runtime.
Example
using
System;
using
System.Collections.Generic;
using
System.Linq;
using
System.Text;
namespace
dynamic_variable_in_c_sharp
{
class
Program
{
static
void Main(string[]
args)
{
dynamic a =
10;
//Create Dynamic
variable a, which value assige as int type
dynamic b =
"Hello";
//Create Dynamic variable b,
which value assige as string type
dynamic c =
5.4;
//Create Dynamic
variable c, which value assige as double type
dynamic
result1;
dynamic
result2;
dynamic
result3;
result1 = a + b;
//Dynamic variable result1, which store sum of int and
string type value
result2 = b + c;
//Dynamic variable result2, which store sum of string and
double type value
result3 = c + a;
//Dynamic variable result3, which store sum of double and
int type value
Console.WriteLine("Sum
of Dynamic value a + b is : {0}",result1);
Console.WriteLine("Sum
of Dynamic value b + c is : {0}", result2);
Console.WriteLine("Sum
of Dynamic value c + a is : {0}", result3);
Console.ReadLine();
}
}
}
