But you can find Yet another, extra subtle variance that we should always be aware of. If a const variable exists in Assembly A and is also Employed in Assembly B, when Assembly A gets recompiled that has a new value to the const variable Assembly B will continue to possess the past
I compiled above sample program as a class library(A) and utilized it in Yet another undertaking (in B) being a reference. Now begin to see the created IL code of job B
Are good practice, you'll want to use readonly where ever simple in the beginning. When you learn that You'll need a mutable area later, you can remove the readonly modifier. Take note that immediately after Considerably complaining, Microsoft ultimately additional computerized Houses with readonly backing fields by making it possible for you to assign to an automatic with only get defined concurrently you can by having an specific readonly industry (inside the constructor or to be a default worth towards the definition).
We then recompile Assembly A and deploy it, and it'll have the new value for CONSTANT_NUMBER. Dilemma is, Assembly B will however have the value be 6 as it hasn't been recompiled to incorporate the new worth. Here is the initial StackOverflow response describing this phenomenon.
Within a function, it continues to be a persistent variable, so you could possibly As an illustration rely the number of situations a purpose is known as.
The distinction between non-static and read-only variables are non-static variable values could be modified where by as browse-only variables values can’t be modified

Also does the fifth row in the primary table suggest that readonly fields can only be of primitive sorts far too?
Those people characteristics, combined with its potent enhancement instruments, multi-System guidance, and generics, make C# a good choice For numerous forms of computer software development jobs: quick application development jobs, initiatives applied by individuals or significant or modest teams, World-wide-web apps, and assignments with stringent reliability prerequisites. Screening frameworks like NUnit make C# amenable to check-pushed improvement and so an excellent language for use with Serious Programming (XP). Its robust typing helps to circumvent several programming errors which have been widespread in weakly typed languages.

So yes, the code inside your read more final instance is valid, since you are passed in an instance. Nonetheless, you may not do:
Now we will go throughout the differences among const and readonly fields, As outlined in the second place for const fields no memory allocated and the worth instantly embedded in IL code. make sure you begin to see the below photo of IL code. (Couple distinctions spelled out in above put up)
Readonly may be the key phrase whose value we can easily transform throughout runtime or we can easily assign it at run time but only through the non-static constructor. Not even a way. Let's have a look at:
