F#忽略缺失忽略

我经常以互动的方式使用F#。我在VisualStudio的脚本文件中键入语句，然后按

Alt+Enter

，在F#Interactive中执行它们。 我经常看到这样的警告：我忽略了表达式的结果。我当然不是，因为我以交互方式评估一切

是否有关闭此警告的选项

例如：

let numbers = "151,160,137,91,90,15"
numbers.ToCharArray() 
|> Array.filter (fun e-> e=',')
|> Array.length

F#Interactive有多种功能，包括一个用于抑制编译器警告消息的功能：

--nowarn:<warning-list>

F#交互式返回

Script.fsx(9,7): warning FS0025: Incomplete pattern matches on this expression. 
For example, the value '[]' may indicate a case not covered by the pattern(s).

这是您要与

#nowarn

一起使用的警告代码的最后几位，请不要忘记数字周围的引号

因此，对于FS0025来说，它是

#nowarn“25”

非常感谢#诺瓦恩“0020”做到了！：-）写一个答案#nowarn“20”修复了“绑定结果！”-警告：-）
