Date Time Format is not Formatting

Question

I need have this format : aaaa-mm-jjThh:mm:sszzzzzz

And put it in a XML property "DateTime" type.

So, I did it :

var xmlObj= new xmlObj.tHeader();
xmlObj.prop = DateTime.ParseExact(DateTime.Now.ToString("yyyy'-'MM'-'dd'T'HH':'mm':'ss'Z'"), "yyyy'-'MM'-'dd'T'HH':'mm':'ss'Z'", CultureInfo.InvariantCulture);

Console.WriteLine(xmlObj.prop);

The Console.WriteLine instruction return : 03/05/2016 15:43:10

I don't understand why the property remove the format.

In the XSD, this property is waiting a datetime format.

Any ideas?

EDIT :

Ok, on the command result, I see a default format but If convert my XML object to File, the format is correct :

Very strange... but it's ok now. Many thanks to all of you

Answer 1

You are calling DateTime.ParseExact , which parses a string into a DateTime object. Just drop that part and assign the result of ToString directly to xmlObj.prop , or assign the DateTime object directly (if that's what it's looking for).

Edit:

To address your edit, your XML file is generated correctly. However, when you output the DateTime prop to the console, it uses the default string format for a date. You can format that with ToString() if you want to.

Answer 2

您可以尝试以下方法：

Console.WriteLine(DateTime.UtcNow.ToString("s") + "Z");

Answer 3

Your format is wrong in parse, if you want yyyy-MM-ddTHH:mm:ssz format then you have to convert it as string otherwise, it will represent standard datetime, try this

xmlObj.prop = DateTime.ParseExact(DateTime.Now.ToString("yyyy-MM-ddTHH:mm:ssZ"), "yyyy-MM-ddTHH:mm:ssZ", CultureInfo.InvariantCulture);
Console.WriteLine(xmlObj.prop.ToString("yyyy-MM-ddTHH:mm:ssz"));
