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服务器之家其它相关文章！
