Read-Only vs const in C#: Understand the Key difference between read-only and const keyword in C#

Difference between const and readonly:

The primary difference between read-only and const keywords is that const represents a compile-time constant, whereas read-only is a runtime constant.

The Constant variables must be initialized at compile-time with fixed values. Their values are known during compilation and, once assigned, cannot be changed afterwards.

On the other hand, Read-Only variables are also immutable. They can be assigned a value either at the time of declaration or at runtime within the constructor but cannot be modified afterwards for the life of the program.
