1.打开VS选择控制台项目新建一个解决方案Server,然后添加两个类库Contract和Service.
2.在Contract中添加一个接口IFileDownload
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ServiceModel; namespace Contract
{
[ServiceContract]
public interface IFileDownload
{
[OperationContract]
Dictionary<string, byte[]> DownloadFile(string[] fileNames);
}
}
3.在Service中实现接口IFileDownload
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Contract;
using System.IO; namespace Service
{
public class FileDownload : IFileDownload
{
public Dictionary<string, byte[]> DownloadFile(string[] fileNames)
{
Dictionary<string, byte[]> filedata = new Dictionary<string, byte[]>();
string queryDirectory = AppDomain.CurrentDomain.BaseDirectory + "数据"; //假设服务器数据存放在运行目录下的“数据”文件夹中
DirectoryInfo drtInfo = new DirectoryInfo(queryDirectory);
FileInfo[] fileInfo = drtInfo.GetFiles();
foreach (FileInfo item in fileInfo)
{
foreach (string filename in fileNames)
{
if (filename == item.Name)
{
FileStream fsRead = new FileStream(queryDirectory+"\\"+filename,FileMode.Open,FileAccess.Read);
byte[] bytDt = new byte[fsRead.Length];
fsRead.Read(bytDt,,bytDt.Length);
fsRead.Close();
filedata.Add(filename,bytDt);
break;
}
}
} return filedata;
}
}
}
3.在Server中添加如下代码
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ServiceModel;
using Service; namespace Server
{
class Program
{
static void Main(string[] args)
{
ServiceHost download_host = new ServiceHost(typeof(FileDownload));
download_host.Open();
Console.WriteLine("文件下载服务已启动");
Console.Read();
}
}
}
4.在Server中添加一个应用程序配置文件App.xml,并选择菜单栏->工具->WCF服务配置编辑器对配置文件进行编辑，具体操作可参考http://www.cnblogs.com/judastree/archive/2012/08/26/2657555.html
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.serviceModel>
<bindings>
<netTcpBinding>
<binding name="DownloadFileBindingConfig" closeTimeout="20:56:00" openTimeout="20:30:00" sendTimeout="20:56:00" maxBufferSize="2073741824" maxReceivedMessageSize="2073741824" transferMode="Buffered" maxBufferPoolSize="2073741824" >
<security mode="None">
<transport clientCredentialType="Windows" protectionLevel="EncryptAndSign"/>
<message clientCredentialType="Windows"/>
</security>
</binding>
</netTcpBinding>
</bindings>
<behaviors>
<serviceBehaviors>
<behavior name="DownloadBehavior">
<serviceMetadata httpGetEnabled="false"/>
</behavior>
</serviceBehaviors>
</behaviors>
<services>
<service name="Service.FileDownload" behaviorConfiguration="DownloadBehavior">
<endpoint address="net.tcp://localhost:2310/Download" binding="netTcpBinding"
bindingConfiguration="DownloadFileBindingConfig" contract="Contract.IFileDownload" />
<endpoint address="mex" binding="mexTcpBinding" contract="IMetadataExchange" />
<host>
<baseAddresses>
<add baseAddress="net.tcp://localhost:2310" />
</baseAddresses>
</host>
</service>
</services>
</system.serviceModel>
</configuration>
5.启动Server
6.新建一个窗体应用程序的解决方案Client，添加服务引用
7.修改Client的配置文件app.xml为
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.serviceModel>
<bindings>
<netTcpBinding>
<binding name="NetTcpBinding_IFileDownload" maxBufferSize="2073741824" maxReceivedMessageSize="2073741824">
<security mode="None" />
</binding>
</netTcpBinding>
</bindings>
<client>
<endpoint address="net.tcp://localhost:2310/Download" binding="netTcpBinding"
bindingConfiguration="NetTcpBinding_IFileDownload" contract="ServiceReference1.IFileDownload"
name="NetTcpBinding_IFileDownload" />
</client>
</system.serviceModel>
</configuration>
8.添加一个TextBox和一个Button，在Button下添加代码
private void button1_Click(object sender, EventArgs e)
{
ServiceReference1.FileDownloadClient fileDownload = new ServiceReference1.FileDownloadClient();
List<string> filenames = new List<string>();
filenames.Add(textBox1.Text); //为了简单，这里只查找一个文件
Dictionary<string,byte[]> downloadfiles = fileDownload.DownloadFile(filenames.ToArray());
foreach (var item in downloadfiles)
{
if (item.Value!=null)
{
FileStream fsWrite = new FileStream(@"C:\Users\yujian\Desktop\DownloadFiles\"+item.Key,FileMode.Create);//这里下载wav文件，可根据实际情况调整
fsWrite.Write(item.Value,,item.Value.Length);
fsWrite.Close();
}
}
MessageBox.Show("下载成功");
}
9.运行结果
