Question

I ran across a piece of C# code today I had not seen before. The programmer defined a block of code using only curly braces (no if, class, function, etc).

{
    int i = 0;
}
i++; //compile error

Is there a purpose to this other than making the code look more organized? Is it good, bad, or whatever practice to use this “floating” contexts?

Answer 1

You can use an open and close set of curly braces to define a self containing block, which has its own scope.

This is generally not considered good programming practice, though.

Usually if someone is doing something like this, it’s probably better to create a method/function in its place.
