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             else
12             {
13                 //获取printupdate目录下update.exe的修改日期返回
14                 string path = Path.Combine(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                     {
24                         var dt = File.GetLastAccessTime(item);
25                         strXml.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         }

 8                 httpResult.Result = false;
 9                 httpResult.ErrorMessage = "无权限访问";
10             }
11             else
12             {
13                 string path = Path.Combine(HttpRuntime.AppDomainAppPath + "printupdate", file);
14                 if (!File.Exists(path))
15                 {
16                     httpResult.KeyValue = "";
17                     httpResult.Result = false;
18                     httpResult.ErrorMessage = "文件不存在";
19                 }

25             return new HttpResponseMessage { Content = new StringContent(httpResult.ToJson(), Encoding.GetEncoding("UTF-8"), "application/json") };

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。
