I compiled previously mentioned sample method as a class library(A) and utilised it in another undertaking (in B) to be a reference. Now see the produced IL code of task B
Browse-only variables are can’t be modified right after initialization where by as constant variables are can’t be modified following declaration
static means that it is a value not linked to an occasion, and it could be improved at run-time (since it is not readonly).
In a function, it remains a persistent variable, so you can As an example rely the quantity of periods a functionality has long been called.
To accessibility this variable, i have to reference y. If x was static nonetheless, I'm able to accessibility this variable without references to y. That's The ultimate way to go, inside of a situation whereby several strategies inside the course y might be referencing this value ?
I have found scenarios wherever It truly is valuable to utilize static variables inside of functions. Just what the perform does for your variable is it provides a scope for its visibility, not its lifetime (just like computerized regional variables).

Individuals functions, combined with its effective advancement tools, multi-System guidance, and generics, make C# a sensible choice For several forms of application growth tasks: rapid software growth tasks, projects executed by persons or huge or modest teams, Web purposes, and initiatives with rigid reliability prerequisites. Screening frameworks including NUnit make C# amenable to test-pushed advancement and therefore a good language to be used with Severe Programming (XP). Its powerful typing allows to forestall several programming errors that happen to be frequent in weakly typed languages.
This means that For those who have code for example "static int a=0" in a very sample function, and this code is executed in a first get in touch with of this purpose, although not executed inside of a subsequent call from the function; variable (a) will nevertheless have its recent benefit (such as, a current value of 5), because the static variable will get an Preliminary price just one time.
up vote five down vote Constants cannot Static vs Non static vs const vs Readonly Variables be transformed, static variables have a lot more to try and do with how These are allotted and in which They may be accessible.
In OOP, static variables are employed for values which can't be stored by an occasion variable. Illustration: intended you desired to keep a depend of what number of cases of a class exists? How would you store that in only one occasion?
In case you are unsure of whether the worth will transform, but you don't want other lessons or code to be able to adjust it, use readonly.
