c# - Using JSON to Serialize/Deserialize TimeSpan

Question

I'm trying to deserialize/serialize a timespan with Newtonsoft.Json.JsonConvert, but when the JSON is sent it's set to 00:00:00.

Is this even possible to do?

Answer 1

I tried #Jessycormier's method and it didn't work for me. I ran DataContractJsonSerializer to see what it would generate and I found that gave me a value that looked more like this.

{"PassedTimeSpan":"P1DT2H3M4S"}

The value shown above was for 1 day, 2 hours, 3 minutes, and 4 seconds.

So it looks like format is:

[-]P[{days}D][T[{hours}H][{min}M][{sec}S]]

Where:

- Indicates negative timespan, omitted for positive values
P must be the first character (unless negative time value)
T must precede the time portion of the timespan.
[] = optional part that may be omitted if 0.
