WCF之Windows宿主(可安装成服务自动并启动)
- 创建解决方案WCFServiceDemo
- 创建WCF服务库(类库或WCF服务库)WCFService ,添加引用System.ServiceModel、System.Runtime.Serialization
图1:图2:
- 创建实体模型Book
using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.Text;
using System.Threading.Tasks;
namespace WCFService.Models
{
[DataContract]
[Serializable]
public class Book
{
[DataMember]
public string Name { get; set; }
[DataMember]
public double Price { get; set; }
}
}
- 创建实现类BookService
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using WCFService.Models;
namespace WCFService
{
public class BookService : IBookService
{
List<Book> list = new List<Book>();
public bool Add(string name, double price)
{
list.Add(new Book() { Name = name, Price = price });
return true;
}
public List<Book> GetList()
{
return list;
}
}
}
- 创建接口IBookService(接口必须加上ServiceContract特性,方法必须加上OperationContract特性)
using System;
using System.ServiceModel;
namespace WCFService
{
[ServiceContract]
public interface IBookService
{
[OperationContract]
bool Add(string name, double price);
[OperationContract]
System.Collections.Generic.List<WCFService.Models.Book> GetList();
}
}
- 如图:
- 创建Windows服务宿主WindowsServiceHost ,添加引用System.ServiceModel、System.Runtime.Serialization
图3:图4:
- 修改Service1的属性
在Service1的设计界面中右击,选择“属性”,把其中的(Name)和ServiceName都改为BookServiceHost
编写代码:
using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Diagnostics; using System.Linq; using System.ServiceModel; using System.ServiceProcess; using System.Text; using System.Threading.Tasks; using WCFService; namespace WindowsServiceHost { public partial class BookServiceHost : ServiceBase { ServiceHost _Host = new ServiceHost(typeof(BookService)); public BookServiceHost() { InitializeComponent(); } protected override void OnStart(string[] args) { _Host.Open(); } protected override void OnStop() { _Host.Close(); } } }
