Question

如何将F＃函数传递给C＃构造函数？

我有以下用F＃编写的ViewMode：

type ViewModel(submitFn:Try.SubmitFn) as x =
   ...

我正在尝试从C＃实例化这个视图模型：

var cs_submit = FSharpFunc<ValidatedForm, FSharpResult<ProfileRequest,ValidatedForm>>.ToConverter(Try.submit);
DataContext = new ViewModel(cs_submit);

错误

这是我收到的错误：

> cannot convert from 'method group' to
 FSharpFunc<ValidatedForm, FSharpResult<ProfileRequest,ValidatedForm>>

附录

我试图传递给C＃代码的实际F＃函数如下：

module Try
...
type SubmitFn = ValidatedForm -> Result<Profile, ValidatedForm>

let submit : SubmitFn = 
    fun registration -> Error registration

Answer 1

我使用了 FromConverter 而不是 ToConverter ：

var cs_submit = FSharpFunc<ValidatedForm, FSharpResult<ProfileRequest,ValidatedForm>>.FromConverter (Try.submit);
DataContext = new ViewModel(cs_submit);
