In a coding standards document, I found this statement:
Avoid using foreach to iterate over
immutable value-type collections.
E.g. String arrays.
Why should this be avoided ?
You shouldn’t avoid it. The coding standard document you’re reading is talking nonsense. Try to find the author and ask him to explain.
Aside from anything else,
stringis a reference type and arrays are always mutable… this makes me concerned about the quality of the rest of the document, to be honest. Are there any other suspicious recommendations?(It’s possible that “immutable” was meant to refer to the value type rather than the collection – the fact that it’s ambiguous is another worrying sign, IMO.)
