EnvelopeVersion Class

Contains information related to the version of SOAP associated with a message and its exchange.


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

public sealed class EnvelopeVersion

The EnvelopeVersion type exposes the following members.

Public propertySupported by Portable Class LibraryNextDestinationActorValueGets a string that contains the URI name for the SOAP role associated with the current message version for the next destination.
Public propertyStatic memberSupported by Portable Class LibraryNoneGets the envelope version not using a version of SOAP.
Public propertyStatic memberSupported by Portable Class LibrarySoap11Gets the SOAP1.1 envelope version.
Public propertyStatic memberSupported by Portable Class LibrarySoap12Gets the SOAP1.2 envelope version.

Public methodSupported by Portable Class LibraryEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodSupported by Portable Class LibraryFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodSupported by Portable Class LibraryGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodSupported by Portable Class LibraryGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodSupported by Portable Class LibraryGetUltimateDestinationActorValuesGets a string that contains the URI name for the SOAP role associated with the current message version for the ultimate destination.
Protected methodSupported by Portable Class LibraryMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodSupported by Portable Class LibraryToStringGets a string that represents the current envelope version. (Overrides Object.ToString().)

The SOAP versions currently available are SOAP 1.1 and SOAP 1.2. There is an EnvelopeVersion for each of these versions of SOAP that can be recovered using the Soap11 and Soap12 properties. There is also a None message version that is used to sent and receive XML messages that do not use SOAP formatting. The processing roles associated with each message version can be recovered using the NextDestinationActorValue property and the GetUltimateDestinationActorValues method.

The following code shows how to access the methods and properties of EnvelopeVersion.

using System;
using System.Collections.Generic;
using System.ServiceModel;
using System.Text;

namespace CS
    class Program
        static void Main(string[] args)

     // MessageVersion
     EnvelopeVersion envS11 = EnvelopeVersion.Soap11;
     string nextDestS11 = envS11.NextDestinationActorValue;
     string[] ultDestsS11 = envS11.GetUltimateDestinationActorValues();
     string ultS11 = ultDestsS11[0];
     string toStrS11 = envS11.ToString();

     EnvelopeVersion envS12 = EnvelopeVersion.Soap12;

     EnvelopeVersion envNotSOAP =  EnvelopeVersion.None;

     string nextDestS12 = envS12.NextDestinationActorValue;

     string[] ultDestsS12 = envS12.GetUltimateDestinationActorValues();

     string ultS12 = ultDestsS12[1];

     string toStrS12 = envS12.ToString();

     EnvelopeVersion envNone = EnvelopeVersion.None;
     string nextDestNone = envNone.NextDestinationActorValue;
     //The following code throws a System.ArgumentReferenceExeption.
     //The object reference is not set to an instance of an object
     // string[] ultDestsNone = envNone.GetUltimateDestinationActorValues();
     string toStrNone = envNone.ToString();

     Console.WriteLine("EnvelopeVersion.Soap11: {0}", envS11);

     Console.WriteLine("UltDest EnvelopeVersion.Soap12: {0}", ultS12);
     //Console.WriteLine("UltDest EnvelopeVersion.None: {0}", ultDestsNone);

     Console.WriteLine("EnvelopeVersion.Soap11.ToString(): {0}", toStrS11);
     Console.WriteLine("EnvelopeVersion.Soap11.ToString(): {0}", toStrS12);
      Console.WriteLine("EnvelopeVersion.Soap11.ToString(): {0}", toStrNone);
