WCF- 契约Contract(ServiceContract、OperationContract、DataContract、ServiceKnownType和DataMember)(转)
示例
1、服务
IPersonManager.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ServiceModel;
using System.Runtime.Serialization;
namespace WCF.ServiceLib.Contract
{
/**//// <summary>
/// 人员管理接口
/// </summary>
// Namespace - 服务契约的命名空间
// Name - 服务契约的名称(会对应到相关的wsdl,默认情况下本例为接口名“IPersonManager”)
// ConfigurationName - 服务契约在宿主中所配置的服务名称(默认情况下本例为类的全名“WCF.ServiceLib.Contract.IPersonManager”)
[ServiceContract(Namespace = "http://webabcd.cnblogs.com", Name = "IPersonManager", ConfigurationName = "ConfigurationNameTest")]
// 服务已知类型 - Student(数据契约)继承自Person(数据契约),要指定Student为已知类型,其才会被序列化
[ServiceKnownType(typeof(Student))]
public interface IPersonManager
{
/**//// <summary>
/// 获取某人的姓名
/// </summary>
/// <param name="p">Person对象</param>
/// <returns></returns>
// Name - 操作契约的名称(会对应到相关的wsdl,默认情况下本例为方法名“GetName”)
[OperationContract(Name="GetPersonName")]
string GetName([MessageParameter(Name = "person")] Person p);
}
}
PersonManager.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ServiceModel;
using System.Runtime.Serialization;
namespace WCF.ServiceLib.Contract
{
/**//// <summary>
/// 人员管理类
/// </summary>
public class PersonManager : IPersonManager
{
/**//// <summary>
/// 获取某人的姓名
/// </summary>
/// <param name="p">Person对象</param>
/// <returns></returns>
public string GetName(Person p)
{
return "Name: " + p.Name;
}
}
}
Person.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ServiceModel;
using System.Runtime.Serialization;
namespace WCF.ServiceLib.Contract
{
/**//// <summary>
/// Person的实体类
/// </summary>
// Name - 数据契约的名称(会对应到相关的wsdl,默认情况下本例为类名“Person”)
[DataContract(Name = "PersonModel")]
public class Person
{
/**//// <summary>
/// Person的实体类的Age属性
/// </summary>
// Name - 数据成员的名称(会对应到相关的wsdl,默认情况下本例为属性名“Age”)
// IsRequired - 该值指示序列化引擎该成员在读取或反序列化时必须存在
// Order - 数据成员在相关的wsdl中的顺序
// EmitDefaultValue - 如果应该在序列化流中生成成员的默认值,则为 true,否则为 false,默认值为 true
[DataMember(Name = "PersonAge", IsRequired = false, Order = 1)]
public int Age { get; set; }
/**//// <summary>
/// Person的实体类的Name属性
/// </summary>
// Name - 数据成员的名称(会对应到相关的wsdl,默认情况下本例为属性名“Name”)
// IsRequired - 该值指示序列化引擎该成员在读取或反序列化时必须存在
// Order - 数据成员在相关的wsdl中的顺序
// EmitDefaultValue - 如果应该在序列化流中生成成员的默认值,则为 true,否则为 false,默认值为 true
[DataMember(Name = "PersonName", IsRequired = false, Order = 0)]
public string Name { get; set; }
}
