在 Azure DevOps Rest Api 中处理日期

Question

I am pulling data from work item changes in ADO calling

https://dev.azure.com/{organization}/{project}/_apis/wit/workItems/{id}/updates?api-version=6.0

Unfortunately I am getting values back that look like

"System11111ChangedDate": {
   "oldValue": "2021-09-28T23:59:171111146Z",
   "newValue": "2021-09-28T23:59:2411111677Z"
}

and when I take

string dt = "2021-09-28T23:59:2411111677Z";
DateTime.Parse(dt, null, System.Globalization.DateTimeStyles.RoundtripKind);

I get

{"String '2021-09-28T23:59:2411111677Z' was not recognized as a valid DateTime."}

I have been messing around with this for a while and still have yet to get it to work.

Any thoughts on how I can do this conversion?

TIA

Answer 1

• The original format for ISO 8601 is "yyyy-MM-ddTHH:mm:ss.fffffffz"

• The string which you have provided is not in a correct format. One (.) dot is missing after seconds ( ie, 24 in your string).

• I have tried using the same given format by adding the extra dot

   string dt = "2021-09-28T23:59:24.11111677Z"; DateTime dt1 = DateTime.Parse(dt, null, System.Globalization.DateTimeStyles.RoundtripKind);

Got the below output

9/28/2021 11:59:24 PM
