c# - 我必须压缩 responseStream 但流不可写。我已经编写了这段代码但它不起作用（C# 中的 GZip 压缩）

Question

try
{
   TextReader reader = new StreamReader(responseStream);
   gzipBytes = ASCIIEncoding.ASCII.GetBytes(reader.ToString());

   MemoryStream ms = new MemoryStream();
   // Use the newly created memory stream for the compressed data.
   outStream = new GZipStream(ms, CompressionMode.Compress, true);
   outStream.Write(gzipBytes, 0, gzipBytes.Length);
   // Close the stream.
 }
 catch
 {
 }

试试这个，看看它是否不适合你：

using (Stream inputStream = ...)
using (MemoryStream outputStream = new MemoryStream())
using (GZipStream zipStream = new GZipStream(outputStream, CompressionMode.Compress, true))
{
    inputStream.CopyTo(zipStream);
}

您所要做的就是用Stream inputStream = ...您的输入流替换第一行，例如：Stream inputStream = File.OpenRead(...)或Stream inputStream = new StreamReader(...)...随便什么。应该复制到zipStream并执行压缩。

另外，using积木也不错。它们释放非托管资源，而不是让它们四处飘荡，直到垃圾收集器捡起它们。
