1. 解决方案中添加引用：SevenZipSharp.dll
2. 复制粘贴两个dll文件：7z.dll 7z64.dll，并将属性“复制到输出目录”修改为“如果较
新则复制”

//测试压缩
var zip = new SevenZipCompressor();
zip.CompressionLevel=CompressionLevel.High;
zip.CompressDirectory(@"c:\doc", @"c:\arch.7z");

//测试解压
using (var tmp = new SevenZipExtractor(@"c:\arch.7z"))
{
for (var i = 0; i < tmp.ArchiveFileData.Count; i++)
{
tmp.ExtractFiles(@"C:\cygwin\", tmp.ArchiveFileData[i].Index);
}
}
