如何创建F#中的记录类型通过使用反射?谢谢
How can I create a record type in F# by using reflection? Thanks
推荐答案您可以使用FSharpValue.MakeRecord[MSDN]创造纪录的实例,但我不认为有什么烤成F#定义记录的类型的。然而,记录编译成简单的类,这样你就可以建立一个类,你会在C#。 TypeBuilder[MSDN]可能是一个很好的起点。
You can use FSharpValue.MakeRecord[MSDN] to create a record instance, but I don't think there's anything baked into F# for defining record types. However, records compile to simple classes, so you could build a class as you would in C#. TypeBuilder[MSDN] may be a good starting point.
添加 [< CompilationMapping(SourceConstructFlags.RecordType)GT;] 的类型是所有的需要,使之成为记录。下面是如何在运行时做一个这样的例子。
Adding [<CompilationMapping(SourceConstructFlags.RecordType)>] to the type is all that's required to make it a record. Here's an example of how to do this at run-time.
let asmName = AssemblyName("Foo") let asm = AppDomain.CurrentDomain.DefineDynamicAssembly(asmName, AssemblyBuilderAccess.RunAndCollect) let moduleBldr = asm.DefineDynamicModule("Test") let typeBldr = moduleBldr.DefineType("MyRecord", TypeAttributes.Public) let attrBldr = CustomAttributeBuilder( typeof<CompilationMappingAttribute>.GetConstructor([|typeof<SourceConstructFlags>|]), [|box SourceConstructFlags.RecordType|]) typeBldr.SetCustomAttribute(attrBldr) let typ = typeBldr.CreateType() printfn "%b" <| FSharpType.IsRecord(typ) //true更多推荐
