详解C# WinForm如何实现自动更新程序的案例分享

实现代码

//xml文件

<?xml version="1.0" encoding="utf-8" ?>

<updateList>

<url>http://localhost:5000/api/Update/</url>

<files>

<file name="1.dll" version="1.0"></file>

<file name="1.dll" version="1.1"></file>

<file name="AutoUpdate.Test.exe" version="1.1"></file>

</files>

</updateList>

//Model

public class UpdateModel {

public string name { get; set; }

public string version { get; set; }

}

public class UpdateModel_Out {

public string url { get; set; }

public List<UpdateModel> updateList { get; set; }

}

//控制器

namespace AutoUpdate.WebApi.Controllers {

[Route("api/[controller]/[Action]")]

[ApiController]

public class UpdateController : ControllerBase {

[HttpGet]

public JsonResult Index() {

return new JsonResult(new { code = 10, msg = "success" });

}

[HttpPost]

public JsonResult GetUpdateFiles([FromBody] List<UpdateModel> input) {

string xmlPath = AppContext.BaseDirectory + "UpdateList.xml";

XDocument xdoc = XDocument.Load(xmlPath);

var files = from f in xdoc.Root.Element("files").Elements() select new { name = f.Attribute("name").Value, version = f.Attribute("version").Value };

var url = xdoc.Root.Element("url").Value;

List<UpdateModel> updateList = new List<UpdateModel>();

foreach(var file in files) {

UpdateModel model = input.Find(s => s.name == file.name);

if(model == null || file.version.CompareTo(model.version) > 0) {

updateList.Add(new UpdateModel {

name = file.name,

version = file.version

});

}

}

UpdateModel_Out output = new UpdateModel_Out {

url = url,

updateList = updateList

};

return new JsonResult(output);

}

[HttpPost]

public FileStreamResult DownloadFile([FromBody] UpdateModel input) {

string path = AppContext.BaseDirectory + "files\\" + input.name;

FileStream fileStream = new FileStream(path, FileMode.Open);
