Csv Type Provider转换为Json

Question

我正在使用Csv Type Provider从本地csv文件中读取数据。

我想将数据导出为json，因此我将每行使用带有JsonConvert.SerializeObject(x)的json.net库进行序列化。

问题是每一行都被建模为一个元组，这意味着列标题在序列化时不会成为属性名称。相反，我得到Item1 =＆＃34; ...＆＃34 ;;项目2 =＆＃34; ...＆＃34;等

如果没有＆＃39;手动滚动＆＃39;我如何导出到Json？用于保存值和维护属性名称的类/记录类型？

The TypeProvider works by providing compile time type safety. The actual code that is compiled maps (at compile time) the nice accessors to tupled values (for performance reasons, I guess). So at run time the JSON serializer sees tuples only.

AFAIK there is no way around hand-rolling records. (That is unless we eventually get type providers that are allowed to take types as parameters which would allow a Lift<T>-type provider or the CSV type provider implementation is adjusted accordingly.)
