wcf 实现大文件上传（有进度条）

部分win7/win8用户 运行时报错 可能是 权限问题,所以运行项目的时候 要右键>>以管理员身份运行

部分用户 运行该项目的时候 可能提示：协定需要双工 但是绑定 NetTcpBinding 不支持

这是只需要将host项目app.config中协议部分 改为wsDualHttpBinding 即可，如下代码：

      <service name="WcfUploadServiceLib.UpLoadService">
        <endpoint address="" binding="wsDualHttpBinding" bindingConfiguration="DualHttpBinding"
          contract="WcfUploadServiceLib.IUpLoadService">
          <identity>
            <dns value="localhost" />
          </identity>
        </endpoint>
        <endpoint address="mex" binding="mexHttpBinding" bindingConfiguration=""
          contract="IMetadataExchange" />
        <host>
          <baseAddresses>
            <add baseAddress="http://localhost:8890/WcfUploadService/" />
            <add baseAddress="net.tcp://localhost:8888/WcfUploadService/" />
          </baseAddresses>
        </host>
      </service>

另外使用wcf时，最好不要使用 using 因为使用using会屏蔽掉很多错误，误导用户，参考链接：http://www.codeproject.com/Tips/197531/Do-not-use-using-for-WCF-Clients

相关代码改为：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Windows.Forms;
using System.ServiceModel;

namespace WcfUploadServiceHost
{
    static class Program
    {
        /// <summary>
        /// The main entry point for the application.
        /// </summary>
        [STAThread]
        static void Main()
        {
            try
            {

                var host = new ServiceHost(typeof (WcfUploadServiceLib.UpLoadService));
                host.Open();
                Console.WriteLine("Server is opened...");
                Console.Read();

                //using (var host = new ServiceHost(typeof(WcfUploadServiceLib.UpLoadService)))
                //{
                //    host.Open();
                //    Console.WriteLine("Server is opened...");
                //    Console.Read();
                //}
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.ToString());
                Console.Read();
            }
        }
    }
}
