XmlConvert.ToDateTimeOffset Method (String, String[])

 

Converts the supplied String to a DateTimeOffset equivalent.

Namespace:   System.Xml
Assembly:  System.Xml (in System.Xml.dll)

public static DateTimeOffset ToDateTimeOffset(
	string s,
	string[] formats
)

Parameters

s
Type: System.String

The string to convert.

formats
Type: System.String[]

An array of formats from which s can be converted. Each format in formats can be any subset of the W3C Recommendation for the XML dateTime type. (For more information see http://www.w3.org/TR/xmlschema-2/#dateTime.) The string s is validated against one of these formats.

Return Value

Type: System.DateTimeOffset

The DateTimeOffset equivalent of the supplied string.

If the offset specified within the input string will cause an overflow in the deserialized representation of the DateTimeOffset, a FormatException is thrown.

When more than seven digits are specified for fractional seconds, the value is rounded. For example, 00000004 becomes 0000000 and 00000005 becomes 0000001.

The following example demonstrates how to read a string from an XML file and use the ToDateTimeOffset method to convert the string to a DateTimeOffset type. The input string must validate against one of the specified formats before being converted.

using System;
using System.Xml;

class Example
{
    static void Main()
    {
        // Create an XmlReader, read to the "time" element, and read contents as type string
        XmlReader reader = XmlReader.Create("transactions.xml");
        reader.ReadToFollowing("time");
        string time = reader.ReadElementContentAsString();

        // Specify formats against which time will be validated before conversion to DateTimeOffset
        // If time does not match one of the specified formats, a FormatException will be thrown.
        // Each specified format must be a subset of the W3C Recommendation for the XML dateTime type
        string[] formats = {"yyyy-MM-ddTHH:mm:sszzzzzzz", "yyyy-MM-ddTHH:mm:ss", "yyyy-MM-dd"};
        try
        {
            // Read the element contents as a string and covert to DateTimeOffset type
            DateTimeOffset transaction_time = XmlConvert.ToDateTimeOffset(time, formats);
            Console.WriteLine(transaction_time);
        }
        catch (Exception e)
        {
            Console.WriteLine(e);
        }
    }
}

The example uses the transactions.xml file.

<?xml version="1.0"?>
<transactions>
   <transaction>
      <id>123456789</id>
      <amount>1.00</amount>
      <currency>USD</currency>
      <time>2007-08-03T22:05:13-07:00</time>
   </transaction>
</transactions>
