Hi all
i wanted to ask if it is possible to have a kind of variable in c# that behave like static local variable in c++,
I mean I want to have a local variable in a method, that it is assigned (initialize) just the first time the method invoked and after calling the method again and again it would not be initialize again and keep its value from the last time I invoked the method
thank you

If you don't want it to change after initialization declare it static readonly. If you want to be able to change it later but have it retain the value between instances just mark it static.

Solution 2

I want it to be local and in local scope we are not allowed to use static keyword at all, isn't it?

That isn't an answer, it's a comment to my proposed answer therefore you should use the "Add Comment" widget below the post.
If you need class level scope, just create a class level variable.

What you are talking about is something like this:

C++

void SomeFunction(void)
{
   static int sVar = 1;

   ...
}

It is possible to do this in C and C++, but it is not possible in C#. Be aware that the C language is not object oriented and the C++ is a multi paradigm language.

The C# is a pure object oriented language and what you are trying to do break the principles of OOP: if you need a method to persist some state between calls, you should make that state variable a member of the class that contains the method.

Be aware that things that are possible with a programming language, could be not allowed by another language. And again, a coding style could be good with a language and bad with another.
