生成的單個檔案的壓縮率可達50%，忍不住要壓縮一下，當然下載的時候也需要解壓，我用的是GZipStream
1.壓縮
string filePath = ((System.Array)e.Data.GetData(DataFormats.FileDrop)).GetValue(0).ToString();
FileInfo fi = new FileInfo(filePath);
using FileStream msSource = fi.OpenRead();
using MemoryStream msTarget = new MemoryStream();
using GZipStream compressionStream = new GZipStream(msTarget, CompressionMode.Compress);
msSource.CopyTo(compressionStream);
compressionStream.Flush();
compressionStream.Flush();這很重要，否則msTarget.ToArray()會丟掉部分內容，
2.解壓
using MemoryStream mss = new MemoryStream(buffer);
using FileStream mst = File.Create(currentProcess.MainModule.FileName + "~");
using GZipStream decompressionStream = new GZipStream(mss, CompressionMode.Decompress);
decompressionStream.CopyTo(mst);
