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
[HttpGet]
public HttpResponseMessage GetUpdaterList(string key)
{
HttpResult httpResult = new HttpResult();
if (!CheckKey(key))
{
httpResult.KeyValue = "";
httpResult.Result = false;
httpResult.ErrorMessage = "无权限访问";
}
else
{
//获取printupdate目录下update.exe的修改日期返回
string path = Path.Combine(HttpRuntime.AppDomainAppPath, "printupdate");
StringBuilder strXml = new StringBuilder();
strXml.AppendLine("<?xml version=\"1.0\" encoding=\"utf-8\" ?>");
strXml.AppendLine("<files>");
if (Directory.Exists(path))
{
string[] fs = Directory.GetFiles(path, "*.*", SearchOption.AllDirectories);
var _p = path.ToLower().Trim().Length + 1;
foreach (var item in fs)
{
var dt = File.GetLastAccessTime(item);
strXml.AppendLine("<file time=\"" + dt.ToString("yyyy-MM-dd HH:mm:ss") + "\">" + item.Substring(_p) + "</file>");
}
}
strXml.AppendLine("</files>");
httpResult.KeyValue = strXml.ToString();
httpResult.Result = true;
httpResult.ErrorMessage = "";
}
return new HttpResponseMessage { Content = new StringContent(httpResult.ToJson(), Encoding.GetEncoding("UTF-8"), "application/json") };
}

}
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
[HttpGet]
public HttpResponseMessage DownloadUpdaterFile(string key, string file)
{
HttpResult httpResult = new HttpResult();
if (!CheckKey(key))
{
httpResult.KeyValue = "";
httpResult.Result = false;
httpResult.ErrorMessage = "无权限访问";
}
else
{
string path = Path.Combine(HttpRuntime.AppDomainAppPath + "printupdate", file);
if (!File.Exists(path))
{
httpResult.KeyValue = "";
httpResult.Result = false;
httpResult.ErrorMessage = "文件不存在";
}
else
{
httpResult = ConvertToBase64Type(path);
}
}
return new HttpResponseMessage { Content = new StringContent(httpResult.ToJson(), Encoding.GetEncoding("UTF-8"), "application/json") };
}
HttpResult ConvertToBase64Type(string fileName)
{
HttpResult httpResult = new HttpResult();
var byts = File.ReadAllBytes(fileName);
httpResult.KeyValue = Convert.ToBase64String(byts);
return httpResult;
}
bool CheckKey(string key)
{
return key == Encryption.Encrypt(m_strkey);
}
private static string encryptKey = "111222333444";
//默认密钥向量
private static byte[] Keys = { 0x41, 0x72, 0x65, 0x79, 0x6F, 0x75, 0x6D, 0x79, 0x53, 0x6E, 0x6F, 0x77, 0x6D, 0x61, 0x6E, 0x3F };
/// <summary>
/// 加密
/// </summary>
/// <param name="encryptString"></param>
/// <returns></returns>
public static string Encrypt(string encryptString)
{
if (string.IsNullOrEmpty(encryptString))
return string.Empty;
RijndaelManaged rijndaelProvider = new RijndaelManaged();
rijndaelProvider.Key = Encoding.UTF8.GetBytes(encryptKey.Substring(0, 32));
rijndaelProvider.IV = Keys;
ICryptoTransform rijndaelEncrypt = rijndaelProvider.CreateEncryptor();
byte[] inputData = Encoding.UTF8.GetBytes(encryptString);
byte[] encryptedData = rijndaelEncrypt.TransformFinalBlock(inputData, 0, inputData.Length);
return Convert.ToBase64String(encryptedData);
}
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。
以上就是用c# 自动更新程序的详细内容，更多关于c# 自动更新程序的资料请关注自学编程网其它相关文章！
