✅ How to Deserialize dd-MM-yyyy in System.Text.Json?
Hi guys. It seems I can happily deserialize a yyyy-MM-dd formatted date in C# using System.Text.Json
However, when I try with a dd-MM-yyyy formatted date, I get the error:
The JSON value could not be converted to System.DateTime
How can I accept both date formats in System.Text.Json?17 Replies
You would need a custom converter I believe
Or, if at all possible, make the JSON conform to the standard
no it needs to be the role of the Server to accept both date formats, as the client side can be anyone from any country
i'll look at the custom converter, thanks
Well, sure, anyone from any country... but the standard is ISO 8601
And you are well within your right to reject anything that is not ISO 8601
sure but do u write the client side?
it would make more sense if the client site provides the same format when sending u can still show it to the client in their local format that is no issue.
i.e.: if ur sending it as a string just format it, like your example ToString("yyyy-MM-dd")
its just <input type="Date"> using whatever format the OS/Browser gives.... so dependent on the client OS's local datetime settings I guess
The value of that is always ISO-8601
not for Safari 😅
im not sure why but always whenever i get a dd-MM-yyyy formatted date it's from a safari user
How are you getting that value?
Maybe you're doing some string -> datetime -> string conversion
And it gets localized on the second arrow
its an angular app, im just having a look through to see if i can anyone has configured some custom dateformatters or somethign
Newtonsoft used to auto convert dates which was nice

if this is an angular app, you probably are taking it from input with FormControl, can't you just map is there with
new Date(control.value).toISOString() before sending to api?
I know, it's an Angular response in C# chat, but still a possible solution to a problemUnknown User•8mo ago

this is my example (we dont know how the solutions looks), there is a possibility that
new Date() is not enough, however I think we can both agree that this is a frontend responsibility to adjust to API standard rather than adjusting API for frontend code hereUnknown User•8mo ago
