MessageParameterAttribute.Name 属性

定义

命名空间:

System.ServiceModel

程序集:

System.ServiceModel.Primitives.dll

程序集:

System.ServiceModel.dll

获取或设置 XML 架构 (XSD) 中参数的名称属性。

public:
 property System::String ^ Name { System::String ^ get(); void set(System::String ^ value); };

public string Name { get; set; }

member this.Name : string with get, set

Public Property Name As String

属性值

String

XSD 中参数的名称属性。

示例

下面的代码示例演示如何使用 MessageParameterAttribute 在元数据中建立参数和返回值的名称。

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:complexType>
    </xs:element>
    <xs:element name="SampleMethodResponse">
      <xs:complexType>
        <xs:sequence>
          <xs:element minOccurs="0" name="Output" nillable="true" type="xs:string" />
        </xs:sequence>
      </xs:complexType>
    </xs:element>
  </xs:schema>

   And the message sent is edited for clarity:
  <s:Body>
    <SampleMethod xmlns="http://microsoft.wcf.documentation">
      <Input>hello!</Input>
    </SampleMethod>
  </s:Body>
   */
