Assume, you were being in the position to entry the non-static variable during the static member of The category, Once the static operate is termed, which item's member it requirements to vary?
If your values at any time want to change then enough time taken to change the supply and recompile quickly ruins this marginal effectiveness improve.
As the readonly subject worth differs based upon the constructor used (As spelled out in the above posting). To make it course member (static member) and one of a kind to The category, we will insert static key phrase ahead of the variable as demonstrated below.
const static int x = 42; // ok // Be aware: Since an inline definition is distinctive through the // corresponding external definition and from another // corresponding inline definitions in other translation // models, all corresponding objects with static storage // duration can also be distinct in Just about every in the definitions static int y = -42; // mistake, inline operate definition
All illustrations are compiled and tested on a Visual Studio. These illustrations can be easy C# systems or Sophisticated C# applications. So, They are really suitable for any consumer (dummies, inexperienced persons or Superior people).
This means that a readonly variable may have different values for various constructors in the same class.
Also does the 5th row in the main desk suggest that readonly fields can only be of primitive styles too?
Just last week I had a new-to-ASP.Web developer (we are going to connect with him Roger) inquire me to clarify what the main difference was in between a variable declared as const variable and that same variable declared as static readonly.
Constant variables nonetheless are prevented from switching. A standard use of const and static collectively is inside of a class definition to provide some sort of constant. class myClass
As significantly I am mindful, this benefit will likely be international for all users, but the value is just not guaranteed to exist on account of the application pool recycling and the value is not really assigned on recycle?
So Certainly, the code in your previous illustration is legitimate, because you are passed in an occasion. Having said that, you could not do:
Now we get again on the question Roger initially asked: what's the difference between a variable declared as const and exactly the same variable declared as static readonly?
