The first problem, as @0x686f676779303737 mentioned, is that those are fields, not properties How exactly are you calling System.Text.Json? Are you calling JsonSerializer.Deserialize<WixNameDto>(json)?

i declared it as properties but still dont work yes this way

thats the other thing Canton wanted to point out

Right, so look at your JSON. In the outermost object, it's expecting a key "contact" (And then inside that it's expecting "name", and only inside that is it expecting "first" and "last") So you need to deserialize into an object which has a property "contact"

okay i think it worked with properties thx really much! :kekw:

I don't see how it could possibly work without creating those extra objects, but ok! !close

Closed!

actually i had an object called contactdto and within there was namedto but it was too big to handle so i posted this

That's why I asked the question "Are you calling JsonSerializer.Deserialize<WixNameDto>(json)?", and you said "yes" >< Don't say "yes" if the answer is actually "no" in future, please
