ICSharpCode.SharpZipLib.Zip crc32

我正在使用 ICSharpCode.SharpZipLib.Zip 来压缩文件和文件夹，并使用 response.Binary write 将其作为内存流传递。

这是我的代码：

MemoryStream df= new MemoryStream();                
ZipOutputStream s = new ZipOutputStream(df);
s.SetLevel(9);

byte[] data = (byte[])file.OpenBinary();
s.Write(data, 0, data.Length);
s.Finish();

s.Close();
byte[] outBuf = df.GetBuffer();        
Response.Expires = 0;                 
Response.Buffer = true;                 
Response.ClearContent();                
Response.AddHeader("content-disposition", "inline; filename="out.zip");
Response.ContentType = "application/zip";
Response.BinaryWrite(outBuf);
HttpContext.Current.ApplicationInstance.CompleteRequest();

当我尝试打开 out.zip 文件时，提示 zip 文件已损坏或损坏了，crc值显示为000000，

如何解决？为什么会出现这个错误？

I am using ICSharpCode.SharpZipLib.Zip to compress the files and folders and pass it as memorystream using response.Binary write.

Here is my code:

MemoryStream df= new MemoryStream();                
ZipOutputStream s = new ZipOutputStream(df);
s.SetLevel(9);

byte[] data = (byte[])file.OpenBinary();
s.Write(data, 0, data.Length);
s.Finish();

s.Close();
byte[] outBuf = df.GetBuffer();        
Response.Expires = 0;                 
Response.Buffer = true;                 
Response.ClearContent();                
Response.AddHeader("content-disposition", "inline; filename="out.zip");
Response.ContentType = "application/zip";
Response.BinaryWrite(outBuf);
HttpContext.Current.ApplicationInstance.CompleteRequest();

When I try to open the out.zip file, it is saying that the zip file is either corrupted or
damaged, and the crc value is showing as 000000.

What is the solution for this?
Why is this error is occurring?
