But there is certainly An additional, more refined variation that we should always concentrate on. If a const variable exists in Assembly A and it is Utilized in Assembly B, when Assembly A gets recompiled by using a new price for that const variable Assembly B will however provide the earlier

A variable declared as const (browse: constant) should be assigned a value at declaration, and this benefit may not then adjust in a later time.

Use const when the worth is complete constant that gained’t transform about the time. For instance Quantity of days in per week is 7. This is usually constant. and when doubtful use static readonly to stay away from the dll versioning dilemma.

What static does for variables is assign them a static (non-switching) address in memory. Which means that Until the variable's value is explicitly changed, it may have the identical worth, it doesn't matter what else you happen to be undertaking as part of your code.
Note that When the static is a reference, the readonly attribute won't cease the underlying item from remaining mutated, it only stops the worth on the static variable from becoming altered - in the case of a category reference, that value could be the reference itself.

A static readonly variable is actually a reference, and For that reason a lookup is executed any time this variable is accessed. Having said that, as frequently takes place, the compiler is smarter than you and any intended general performance difference will probably be negated.
And there is no compile time error. Even more I try and yet again improve this variable's benefit. See what happened:
