Readonly vs const c#

readonly keyword is used to define a variable 
which can be assigned once after declaration 
either during declaration or in constructor. 
  
const keyword is used to define a constant to be used in the program.

C# const vs readonly

A const is a compile-time constant whereas readonly allows a value to be calculated at run-time and set in the constructor or field initializer. So, a 'const' is always constant but 'readonly' is read-only once it is assigned.

Eric Lippert of the C# team has more information on different types of immutability.
