Difference between Constant and ReadOnly in C#

Constant:
--------

1. Constant value is declared using "const" keyword.
2. A const needs to be declared and initialized at declaration only.
3. A const’s value is evaluated at design time.
4. A const can not be static.

const string name = "Jeetendra";

ReadOnly:
--------

1. ReadOnly value is declared using "readonly" keyword.
2. A readonly can be initialized at declaration or by the code in the constructor.
3. A readonly’s value is evaluated at runtime.
4. A readonly can be static.

readonly string name = "Jaiswal";
