C# tips and tricks 5 - Difference between const, readonly and static variables

C# tips and tricks :
Difference between const, readonly and static variables

const keyword :
A variable declared as const must be assigned a value at declaration.
And we can not change its value once it is assigned.
They are implicitly static by default.
You can apply const keyword to built-in value types (byte, short, int, long, char, float, double, decimal, bool), enum, a string literal, or a reference type which can be assigned with a value null.

readonly keyword:
The value will be initialized either at declaration time or in the constructor.

 Read only values will evaluate at runtime only.

static keyword:
static variables are common to all the objects.
Each static variable is shared among all the objects of the same class.
and they do not tied to a specific object.

Thank you so much. It was a great explanation

In Case of readonly field, Suppose I have two constructors first is Default constructor as shown in your example along with that I have another constructor
with parameter. Is it possible to change the value of readonly field in that second constructor ? What will happen if I will create two objects first without parameters and second with parameters .

I misunderstand InshaAllah, when u say Initialize 😄❤️

I do not understand why sentence end with "Insallah" repetitive. You do not need to show devotions, it's between you and God. God is giving you knowledge, so embrace the knowledge. Hope you do not mind. You are doing good job.
