利用Zip.js压缩并上传文件，后端使用.Net(Winform)接收转存

没时间解释了，快上车...
前端js:
upload=function ()
{
if(window.FormData)
{
var fileslist=$("input[type='file']");
if(fileslist.length>0)
{
if(fileslist.get(0).files[0]!=undefined)
{
var Thefile=fileslist.get(0).files[0];
UpdateProgressBar(0,"正在压缩..."+"0%");
var zip=new JSZip();
zip.file(Thefile.name, Thefile);
zip.generateAsync({type:"Blob",compression: "DEFLATE",},function updateCallback(metadata){UpdateProgressBar(metadata.percent.toFixed(2),"正在压缩..."+metadata.percent.toFixed(2)+"%");}).then(function(content) //级别：1最快，9最小
{
var file = new File([content],'upload.zip',{type: "zip"});
var dict=new FormData();
dict.append("fileContent",file);
var xhr=new XMLHttpRequest();
xhr.open('POST', USERNAME+";"+obj+";"+date+";"+startTime+";"+endTime,true);
xhr.upload.onprogress=function(event)
{
if(event.lengthComputable)
{
UpdateProgressBar((event.loaded / event.total * 100 | 0),"正在上传..."+(event.loaded / event.total * 100 | 0)+"%");
if((event.loaded / event.total * 100 | 0)>=100)
{
hideUploadProgressBar();
}
}
}
xhr.send(dict);
});
}
}
}
}

有一说一：博客园这些个编辑器是要逼死强迫症吗？
后台c#
HttpListenerContext nowContext = MainHttpListener.EndGetContext(ar)；
HttpListenerRequest request = context.Request;
MemoryStream ms = new MemoryStream();
request.InputStream.CopyTo(ms);
var buff = ms.ToArray();
var msg = System.Text.Encoding.ASCII.GetString(buff);
sec2 = msg;
int index = sec2.IndexOf("PK");//压缩包文件PK开头
string front = sec2.Substring(0, index);
List<byte> A = new List<byte>();
A.AddRange(buff);
List<byte> B = new List<byte>();
B.AddRange(System.Text.Encoding.ASCII.GetBytes(front));
A.RemoveRange(0, B.Count);
byte[] writeBytes = A.ToArray();//此为文件字节，
File.WriteAllByte()存为zip，便可以了，可正常解压;
ConsoleUserColor.SetColorText("文件接收成功");
