SoapDuration Class

Provides static methods for the serialization and deserialization of TimeSpan to a string that is formatted as XSD duration.


Namespace:  System.Runtime.Remoting.Metadata.W3cXsd2001
Assembly:  mscorlib (in mscorlib.dll)

public sealed class SoapDuration

The SoapDuration type exposes the following members.

Public methodSoapDurationCreates an instance of SoapDuration.

Public propertyStatic memberXsdTypeGets the XML Schema definition language (XSD) of the current SOAP type.

Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodStatic memberParseConverts the specified String into a TimeSpan object.
Public methodToString()Returns a string that represents the current object. (Inherited from Object.)
Public methodStatic memberToString(TimeSpan)Returns the specified TimeSpan object as a String.

For more information about XSD data types, see the "XML Data Types Reference" in the MSDN Library at

The following code example shows how to use the methods in the SoapDuration class to convert between a TimeSpan object and an XSD duration string.

using System;
using System.Runtime.Remoting.Metadata.W3cXsd2001;

public class Demo
    public static void Main(string[] args)
        // Parse an XSD duration to create a TimeSpan object.
        // This is a duration of 2 years, 3 months, 9 days, 12 hours, 
        // 35 minutes, 20 seconds, and 10 milliseconds.
        string xsdDuration = "P2Y3M9DT12H35M20.0100000S";
        TimeSpan timeSpan = SoapDuration.Parse(xsdDuration);
        Console.WriteLine("The time span contains {0} days.", 
        Console.WriteLine("The time span contains {0} hours.", 
        Console.WriteLine("The time span contains {0} minutes.", 
        Console.WriteLine("The time span contains {0} seconds.", 

        // Serialize a TimeSpan object as an XSD duration string.
        // This object represents a time span of 399 days, 12 hours,
        // 35 minutes, 20 seconds, and 10 milliseconds.
        TimeSpan duration = new TimeSpan(399, 12, 35, 20, 10);
        Console.WriteLine("The duration in XSD format is {0}.",

        // Print the XSD type string of the SoapDuration class.
        Console.WriteLine("The XSD type of SoapDuration is {0}.",
