The C# Programming Diaries
one @user1566694 I'll point you for the docs for your static keyword. Try to be accessing the static member using the class title to disambiguate Foo.
The actions in the read only variable is very same as non-static variables , that is sustain the different copy for every instance of The category
Go through-only variables are can’t be modified right after initialization in which as constant variables are can’t be modified following declaration
A variable declared as const (examine: constant) must be assigned a value at declaration, which benefit may well not then transform in a later time.
But this new price of the const discipline will not impact in project B until unless we compile the challenge. Immediately after compilation the new const area value are going to be embedded in IL code of project B.
Variable is duplicate of primitive date style like int ,float ,char ,bigint .So the sort of variable will probably be depending on which sort of worth to assign to it
This code will present no mistake and generate a outcome (eleven), due to the fact we declared its price for being static at the time of declaration. So we can easily access it based upon our use in This system.

A constant member is defined at compile time and can't be changed at runtime. Constants are declared like a subject, utilizing the const key phrase and needs check here to be initialized as These are declared. The static modifier is utilized to declare a static member, this means that the member is not tied to a certain object.
Also, with C++0x until C++eleven the usage of the static keyword was deprecated for declaring objects in namespace scope. This deprecation was taken out in C++eleven for different explanations (see below).
If we want to declare const for someclass (non-primitive kinds) we should assign it to null which as of no use.
All statics are initialized if you do not explicitly set a value to them.The manner and timing of static initialization is unspecified
For anyone who is unsure of whether the worth will modify, but you don't need other classes or code in order to change it, use readonly.
At other hand, if you are certain you actually need world vars, Consider the Toolbox pattern. It's a not well known extension of Singleton pattern. It's so unknown actually, should you google for it you won't uncover it with People search phrases (
