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 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 }
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
1 [HttpGet] 2 public HttpResponseMessage DownloadUpdaterFile(string key, string file) 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 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 } 20 else 21 { 22 httpResult = ConvertToBase64Type(path); 23 } 24 } 25 return new HttpResponseMessage { Content = new StringContent(httpResult.ToJson(), Encoding.GetEncoding("UTF-8"), "application/json") }; 26 27 }
1 HttpResult ConvertToBase64Type(string fileName) 2 { 3 HttpResult httpResult = new HttpResult(); 4 var byts = File.ReadAllBytes(fileName); 5 httpResult.KeyValue = Convert.ToBase64String(byts); 6 return httpResult; 7 }
1 bool CheckKey(string key) 2 { 3 return key == Encryption.Encrypt(m_strkey); 4 }
1 private static string encryptKey = "111222333444"; 2 3 //默认密钥向量 4 private static byte[] Keys = { 0x41, 0x72, 0x65, 0x79, 0x6F, 0x75, 0x6D, 0x79, 0x53, 0x6E, 0x6F, 0x77, 0x6D, 0x61, 0x6E, 0x3F }; 5 /// <summary> 6 /// 加密 7 /// </summary> 8 /// <param name="encryptString"></param> 9 /// <returns></returns> 10 public static string Encrypt(string encryptString) 11 { 12 if (string.IsNullOrEmpty(encryptString)) 13 return string.Empty; 14 RijndaelManaged rijndaelProvider = new RijndaelManaged(); 15 rijndaelProvider.Key = Encoding.UTF8.GetBytes(encryptKey.Substring(0, 32)); 16 rijndaelProvider.IV = Keys; 17 ICryptoTransform rijndaelEncrypt = rijndaelProvider.CreateEncryptor(); 18 19 byte[] inputData = Encoding.UTF8.GetBytes(encryptString); 20 byte[] encryptedData = rijndaelEncrypt.TransformFinalBlock(inputData, 0, inputData.Length); 21 22 return Convert.ToBase64String(encryptedData); 23 }
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。
