上传文件压缩后没有后缀名

[爱捉弄你]

上传文件压缩后没有后缀名

public static void CompressFile(string sourceFile, string destinationFile)
{
if (!File.Exists(sourceFile)) throw new FileNotFoundException();
using (FileStream sourceStream = new FileStream(sourceFile, FileMode.Open, FileAccess.Read, FileShare.Read))
{
byte[] buffer = new byte[sourceStream.Length];
int checkCounter = sourceStream.Read(buffer, 0, buffer.Length);
if (checkCounter != buffer.Length) throw new ApplicationException();
using (FileStream destinationStream = new FileStream(destinationFile, FileMode.OpenOrCreate, FileAccess.Write))
{
using (GZipStream compressedStream = new GZipStream(destinationStream, CompressionMode.Compress, true))
{
compressedStream.Write(buffer, 0, buffer.Length);
}
}
}
}

适用上面的代码 上传文件 到制定的地方 后解压开 没有后缀名

是代码本身的问题么......



....大家有更好的代码么 有的话分享下....谢谢啦....

难道是所上传的服务器有问题？或许是服务器启用了“隐藏已知文件类型的扩展名”。。。

不懂，请高人解决……

这么多年了，不知道LZ还在线不。。。今天被同样的问题困扰。于是我用了以下代码解决：
private void dabaoduogewenjian()
{
// 压缩
ZipOutputStream s = new ZipOutputStream(File.Create("D:\\bbbb" + ".zip"));
//生成一个GZipOutputStream流，用来生成压缩文件。
//因为GZipOutputStream由Stream派生，所以它可以赋给Stream。
FileStream fs = File.OpenRead("D:\\bbbb.doc");
FileStream fs1 = File.OpenRead("D:\\data.xml");
//生成一个文件流，它用来打开要压缩的文件
//可以使用System.IO.File的静态函数OpenRead来生成文件流
byte[] writeData = new byte[fs.Length];
//指定缓冲区的大小
fs.Read(writeData, 0, (int)fs.Length);
//读入文件
ZipEntry entry = new ZipEntry("bbbb.doc");
s.PutNextEntry(entry);
s.Write(writeData, 0, writeData.Length);

writeData =new byte[fs1.Length];
fs1.Read(writeData, 0, (int)fs1.Length);
ZipEntry entry1 = new ZipEntry("data.xml");
s.PutNextEntry(entry1);
s.Write(writeData, 0, writeData.Length);

//写入压缩文件
s.Close();
//关闭文件
}
