我正在尝试尽可能快地解析二进制文件。所以这是我首先尝试做的：

using (FileStream filestream = path.OpenRead()) {
   using (var d = new GZipStream(filestream, CompressionMode.Decompress)) {
      using (MemoryStream m = new MemoryStream()) {
         d.CopyTo(m);
         m.Position = 0;

         using (BinaryReaderBigEndian b = new BinaryReaderBigEndian(m)) {
            while (b.BaseStream.Position != b.BaseStream.Length) {
               UInt32 value = b.ReadUInt32();
}  }  }  }  }

哪里 BinaryReaderBigEndian类，因为它实现方式是：

public static class BinaryReaderBigEndian {
   public BinaryReaderBigEndian(Stream stream) : base(stream) { }

   public override UInt32 ReadUInt32() {
      var x = base.ReadBytes(4);
      Array.Reverse(x);
      return BitConverter.ToUInt32(x, 0);
}  }

然后，我尝试使用ReadOnlySpan代替 …
