首先看获取和更新的接口

定义服务端接口，你可以用任意接口都行，我这里用webapi
获取文件列表
1 [HttpGet] 2 public HttpResponseMessage GetUpdaterList(string key) 3 { 4 HttpResult httpResult = new HttpResult(); 5 if (!CheckKey(key)) 6 { 7 httpResult.KeyValue = ""; 8 httpResult.Result = false; 9 httpResult.ErrorMessage = "无权限访问";10 }11 else12 {13 //获取printupdate目录下update.exe的修改日期返回14 string path = bine(HttpRuntime.AppDomainAppPath, "printupdate");15 StringBuilder strXml = new StringBuilder();16 strXml.AppendLine("<?xml version=\"1.0\" encoding=\"utf-8\" ?>");17 strXml.AppendLine("<files>");18 if (Directory.Exists(path))19 {20 string[] fs = Directory.GetFiles(path, "*.*", SearchOption.AllDirectories);21 var _p = path.ToLower().Trim().Length + 1;22 foreach (var item in fs)23 {24var dt = File.GetLastAccessTime(item);25strXml.AppendLine("<file time=\"" + dt.ToString("yyyy-MM-dd HH:mm:ss") + "\">" + item.Substring(_p) + "</file>");26 }27 }28 strXml.AppendLine("</files>");29 30 httpResult.KeyValue = strXml.ToString();31 httpResult.Result = true;32 httpResult.ErrorMessage = "";33 }34 return new HttpResponseMessage { Content = new StringContent(httpResult.ToJson(), Encoding.GetEncoding("UTF-8"), "application/json") };35 }

下载文件，我这里将文件序列号为base64字符串了，你可以直接返回文件流也行

需要注意的地方：
1、我这里用到了json，那么不能直接饮用json的dll文件，会出现更新时候占用的问题，可以使用fastjson的开源代码，放进来解决，你可以直接使用xml格式的返回内容，这样就不需要json了，这样更方便
2、如果你的下载接口是返回的文件流，那么你更新程序里面直接接收流保存文件就行了
3、Program.cs里面，停止服务的功能，其实是可以通过传递参数的形式来停止，我这里写死了，你们根据自己需求修改
效果
你可以根据自己的需求，修改下界面效果，这是最简单的示例界面而已。
