Knowing these nuances is important for gathering strong and dependable functions. Present’s a breakdown of communal contented sorts:
- exertion/json: Utilized for sending JSON information, a communal format for internet APIs.
- matter/plain: Utilized for sending plain matter information.
- exertion/xml: Utilized for sending XML information.
- multipart/signifier-information: Utilized for sending records-data and another signifier information.

Question & Answer :
I’m attempting to fit the Contented-Kind header of an HttpClient entity arsenic required by an API I americium calling.
I tried mounting the Contented-Kind similar beneath:
utilizing (var httpClient = fresh HttpClient()) { httpClient.BaseAddress = fresh Uri("http://illustration.com/"); httpClient.DefaultRequestHeaders.Adhd("Judge", "exertion/json"); httpClient.DefaultRequestHeaders.Adhd("Contented-Kind", "exertion/json"); // ... }
It permits maine to adhd the Judge header however once I attempt to adhd Contented-Kind it throws the pursuing objection:
