类型＆＃39; int＆＃39;不支持运营商＆＃39; ==＆＃39;

Question

我想像这样计算binom：

let t = seq { 1..10 } |> Seq.takeWhile (fun e -> e % 2 == 0)

但编译器抱怨

playground.fsx(27,59): error FS0001: The type 'int' does not support the operator '=='

我做错了什么？

Answer 1

F＃对单个=使用等于运算符：

let t = seq { 1..10 } |> Seq.takeWhile (fun e -> e % 2 = 0)
