目前我完成了我的 PDF webapp 的开发,我可以在其中生成各种 PDF。但是,当用户访问时,我需要为我的手机和计算机提供一个通用的下载 PDF 目录。
至于现在,当我尝试在本地主机上运行我的 web 应用程序时,这就是我保存 PDF 文件的方式。但是,当我在线发布我的 web 应用程序时,并非所有计算机都有类似的文件目录/
var output = new FileStream(Path.Combine("C:\\Users\\apr13mpsip\\Downloads", filename), FileMode.Create);
所以想问问大家有没有关于手机和电脑通用文件目录的想法。
