在F＃中，float []和float list有什么区别？

Question

The compiler is indicating "This expression was expected to have type float []
but here has type float list". I thought "[]" was the syntax for a list. I can't easily simplify the code for posting but perhaps someone can create an example that would generate this error. I searched several web pages on signatures.

Answer 1

In type annotations, [] denotes an array. This is despite the fact that in both patterns and expressions, it denotes lists.

When annotating lists, the syntax float list is usually preferred to the .NET standard notation List<float> , to avoid confusion with System.Collections.Generic.List<> (which has the ResizeArray type abbreviation in F#).
