Date Time XML Serialization

[AnkitSharma127]

Serializing DateTime are removing trailing zeros when we need date in a specific format. Ex I want my date Format to be "2023-05-15T07:45:35.900" "yyyy-MM-ddTHH:mm:ss.fff". But XML Serializer is removing the trailing spaces. Please refer the test below: Where test case 1 is failing and 2 is passing.

using System.IO; using System.Xml; using System.Xml.Serialization;

namespace eDC.Tests.FunctionalTests { public class XmlDateTimeSerializerTest { [Theory] [InlineData(2023, 5, 15, 7, 45, 35, 900, "2023-05-15T07:45:35.900")] [InlineData(2023, 5, 15, 7, 45, 35, 9, "2023-05-15T07:45:35.009")] public void DateSerializeTest(int year, int month, int day, int hour, int minute, int second, int millisecond, string expected) {

        var obj = new DateTime(year, month, day, hour, minute, second, millisecond);

        MemoryStream ms = new MemoryStream();
        XmlWriter xw = XmlWriter.Create(ms, new XmlWriterSettings { Indent = true });
        XmlSerializer serializer = new XmlSerializer(obj.GetType());
        serializer.Serialize(xw, obj);

        StreamReader sr = new StreamReader(ms);
        ms.Position = 0;
        var xml = sr.ReadToEnd().ToString();

        Assert.Contains(expected, xml);
    }
}

}

To serialize a DateTime object to XML in .NET, you can use the following steps:

Create an instance of the XmlSerializer class. Set the DateTimeSerializationMode property of the XmlSerializer object to the desired serialization mode. The possible values for this property are: Local: The DateTime object is serialized in the local time zone. Roundtrip: The DateTime object is serialized in the UTC time zone, and the time zone information is also serialized. Unspecified: The DateTime object is serialized without any time zone information. Serialize the DateTime object to XML using the XmlSerializer object. Here is an example of how to serialize a DateTime object to XML in .NET:

C# using System; using System.Xml; using System.Xml.Serialization;

namespace Serialization { class Program { static void Main(string[] args) { // Create a DateTime object. DateTime dt = new DateTime(2023, 9, 9, 17, 49, 30);

        // Create an XmlSerializer object.
        XmlSerializer serializer = new XmlSerializer(typeof(DateTime));

        // Set the DateTimeSerializationMode property.
        serializer.DateTimeSerializationMode = XmlDateTimeSerializationMode.Roundtrip;

        // Serialize the DateTime object to XML.
        string xml = serializer.Serialize(dt);

        // Print the XML string.
        Console.WriteLine(xml);
    }
}

}

This code will serialize the DateTime object dt to XML in the UTC time zone, and the time zone information will also be serialized. The output of the code will be the following XML string:

XML

2023-09-09T17:49:30Z

The DateTimeSerializationMode property can also be set in the application configuration file. The following is an example of how to set the DateTimeSerializationMode property in the application configuration file:

DateTimeSerializationMode is not a property of the XmlSerializer class ?
