.NetCore使⽤ZipFile类--⽂件的压缩解压
NuGet引⽤官⽹⾃带的System.IO.Compression.ZipFile
var filename = "测试压缩解压⽂件";
var path = Directory.GetCurrentDirectory() + "/wwwroot/file/" + filename + ".pdf";
//这⾥是获取到⽂件的byte数组
byte[] fileBuffer1 = Convert.FromBase64String(invData);
//将byte数组转换为⽂件并保存到指定地址
FileSystem.Bytes2File(fileBuffer1, path);
//添加⽂件到指定压缩⽂件中
ZipFile.CreateFromDirectory(Directory.GetCurrentDirectory() + "/wwwroot/file", Directory.GetCurrentDirectory() + "/wwwroot/" + zipFileName); //删除⽂件夹下的所有⽂件
FileSystem.DeleteDirAllFile(Directory.GetCurrentDirectory() + "/wwwroot/file/");
byte[] fileBuffer;
//⽂件转成byte⼆进制数组
fileBuffer = FileSystem.File2Bytes(Directory.GetCurrentDirectory() + "/wwwroot/" + zipFileName);
//将指定 zip 存档中的所有⽂件都解压缩到⽂件系统的⼀个⽬录下
ZipFile.ExtractToDirectory(Directory.GetCurrentDirectory() + "/wwwroot/" + zipFileName,Directory.GetCurrentDirectory() + "/wwwroot/file");
