What is the difference between var and dynamic Keyword in C#

Answer:

var

If you are use the var keyword, then it valid type against right side value on declaration time

Example:

var data = "name";            
Console.WriteLine(data);

Here var will be string type at compile time.

dynamic

If you are use the dynamic keyword, the type will be decide on run time.

Example:

dynamic data = "name";
data = 8;
Console.WriteLine(data);

it will compile without any error, at run time data variable type is a int than string.because in the second line of code, you have change to string to in value on right hand side.
