如何在 F# 中设置 HttpResponseMessage.Content?

How can I set HttpResponseMessage.Content in F#?

据我了解,应该可以像这样设置响应消息的内容:

let responseMessage = new HttpResponseMessage(HttpStatusCode.OK)
responseMessage.Content = new StringContent("test")

但是,这样做时出现以下错误:

Parser Error: This expression was expected to have type HttpContent but here has type StringContent

我在测试项目中这样做是为了存根响应。它针对 .NET 4.5 和 FSharp Core 4.3.1.0

正如ildjarn所说,=是相等比较,<-是赋值。

let responseMessage = new HttpResponseMessage(HttpStatusCode.OK)
responseMessage.Content <- new StringContent("test")
