Esempio

Nell'esempio di codice seguente viene illustrato l'uso di MessageParameterAttribute per stabilire il nome del parametro e il valore restituito nei metadati.

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

namespace Microsoft.WCF.Documentation
{
  [ServiceContract(Namespace="http://microsoft.wcf.documentation")]
  public interface ISampleService{
    [OperationContract]
    [return:MessageParameter(Name = "Output")]
    string SampleMethod([MessageParameter(Name = "Input")]string msg);
  }

  /*
   The preceding use of MessageParameterAttribute generates the following XSD:

<?xml version="1.0" encoding="utf-8" ?>
  <xs:schema
    elementFormDefault="qualified"
    targetNamespace="http://microsoft.wcf.documentation"
    xmlns:xs="http://www.w3.org/2001/XMLSchema"
    xmlns:tns="http://microsoft.wcf.documentation">
    <xs:element name="SampleMethod">
      <xs:complexType>
        <xs:sequence>
          <xs:element minOccurs="0" name="Input" nillable="true" type="xs:string" />
        </xs:sequence>

        </xs:sequence>
      </xs:complexType>
    </xs:element>

   And the message sent is edited for clarity:
