Web API 2 Patch Delta doesn't deserialize Timespan property

Question

I want to use Patch with Delta to update an object, which has Timespan property i haven't got any error, but the Timespan properties are all 0:00:00, i think they're simple ignored.

i can see 0 at the timespan property just when the method in the controller stops at the breakpoint. i don't make any change on the data at that stage. it is sure i send not empty timespan from the client

{"TevID":2,"TevName":"this is the name","TotalTime":"01:03:00","FreeTime":"02:30:00"}

[HttpPatch]
public async Task<IHttpActionResult> Patch(int id, Delta<TTevekenyseg> modified) {
Log.Info("Update-ID: {0}", id);
...
}

do you have any information, if Delta works for Timespans?

What is your code doing when the timespan is zero? When posting? At any other moment? Please, add soem context to your question. Even better, some sample code. — JotaBe, Jun 15 '15 at 13:17

Delta<T> doesn't work for TimeSpans. It's a pretty flawed class so I wrote my own called Patchable<T>. The main problem I found was Delta<T>'s incompatibility with JSON.Net. Its lack of support for TimeSpan was confirmation I did the right thing.

See the answer to this question (a long read sorry)

The answer has TrySetInt32. The equivalent method TrySetTimeSpan works perfectly.
