對！這又是我全新的一個開篇！之前做過一段時間英文版的網站，現在感覺還是做回中文站比較好。之前做英文站，是因為希望能有更廣闊的空間，可以分享給更多的人，但其實在中文社區也是有非常大的市場和需求的，所以只要能專心做好中文社區也很不錯啦！但雖然轉成中文版了，不過之前英文版的網站我還是會保留的，感興趣的朋友也可以去看看:smile:做了 10 幾年的代碼民工，其實我真是很希望能將自己的經驗分享給有需要的人！我這個部落格將會與大家分享 ASP.NET 方面的技術為主，因為這是畢竟我的老本行 :sunglasses: 。但作為一個代碼民工，本身對這方面的興趣就是無限的，所以除了 .NET 之外，當然也會研究一下其他技術的，如 Angular , 再如跨平台的移動開發技術 Flutter 等，所以之後也會不定期分享一下相關的技術。做此部落格的初衷，除了分享技術與心得外，還希望能結識一些志同道合的朋友，所以很歡迎也喜歡程序設計的你能給我留言一起討論哦！ 😉 ...继续阅读 (87)

Wow, have you heard of MAUI? It’s Microsoft’s latest framework for building cross-platform mobile applications!

In this tutorial, we will walk through the steps to implement a batch upload and processing of PDF files with ASP.NET Core. We will allow clients to upload a ZIP file containing multiple PDF files, extract the ZIP file, read each PDF file’s field values, and finally save the values into a MSSQL database.1. Receive the Upload FileThe first step is to create an API endpoint that allows clients to upload a ZIP file containing multiple PDF files. We can use theIFormFileinterface provided by ASP.NET Core to handle file uploads. Here is an example code snippet:[HttpPost("upload")] public async ...继续阅读 (88)

But it seems as if the first instinct of many ASP.NET MVC developers is to do this by customizing their Controllers, but I will share you a better way that uses an attribute for that. We can inherit aSystem.Web.Mvc.AuthorizeAttributefor do that. You can specifies that access to a controller or action method is restricted to users who meet the authorization requirement.BackgroundFor ...继续阅读 (76)

我其实也是很喜欢唱歌的，所以最近迷上了唱吧，之所以选择唱吧，是因为其是目前这么多唱K软件中感觉做得比较好的，还有就是其社区功能也非常吸引人 因为唱吧中有朋友问我如果制作自己的MV，在这里就写一个比较详细的教程好了:) 所谓自己的MV，并不是直接通过手机即时录影的那种，而是下载你喜欢的MV，然后将自己唱好的歌曲配进去，将原来MV的声音消除，这样感觉就像你在唱歌，然后有明星为你表演一样，可以看看我制作的MV样子先：《几分钟约会》，哈！好了，以下就说说具体的做法： 下载好的MV文件。我在此以陈佰强的《几分钟约会》为例。我是在Youtube上找到此MV，然后通过 http://en.savefrom.net/1-how-to-download-youtube-video/ 此网站将MV下载 在唱吧里用正常的伴奏唱把歌曲唱好，然后导出。这个其实只需将歌曲以微信，QQ形式分享，然后发到你的微信，再通过网页版微信接收，这时点击就可看到你歌曲的网页地址。只要使用 Chrome浏览器，就可以轻松找到真实的歌曲下载地址，如下图所示，在Chrome控制台中打开Network一项，即可找到后缀为MP3的链接啦 3. 由于大部分朋友还是在用Windows，所以我也以windows为例来说明。在Windows里有很多视频处理软件，如绘声绘影就非常出名，但其非常庞大，所以在此推荐另一款比较轻量型的软件，就叫：P ...继续阅读 (97)
