date format yyyy-MM-ddTHH:mm:ssZ

Question

I assume this should be pretty simple, but could not get it :(. In this format Z is time zone.
T is long time pattern
How could I get a date in this format excep

Answer 1

In C# 6+ you can use string interpolation and make this more terse:

$"{DateTime.UtcNow:s}Z"

Answer 2

You could split things up, it would require more code but would work just the way you like it:

DateTime year = DateTime.Now.Year;
DateTime month = DateTime.Now.Month;
DateTime day = DateTime.Now.Day;

ect.

finally:

Console.WriteLine(year+month+day+etc.);

This is a very bold way of handling it though...

Answer 3

It works fine with Salesforce REST API query datetime formats

DateTime now = DateTime.UtcNow;
string startDate = now.AddDays(-5).ToString("yyyy-MM-ddTHH\\:mm\\:ssZ");   
string endDate = now.ToString("yyyy-MM-ddTHH\\:mm\\:ssZ");  
//REST service Query 
string salesforceUrl= https://csxx.salesforce.com//services/data/v33.0/sobjects/Account/updated/?start=" + startDate + "&end=" + endDate;

// https://csxx.salesforce.com/services/data/v33.0/sobjects/Account/updated/?start=2015-03-10T15:15:57Z&end=2015-03-15T15:15:57Z

It returns the results from Salesforce without any issues.
