1.SharpCompress安装
在vs的nuget下搜索安装SharpCompress,如图所示

2.解压缩包功能实现
            
            
              csharp
              
              
            
          
          /// <summary>
/// 解压压缩包
/// </summary>
/// <param name="filePath">压缩包文件路径</param>
/// <param name="directoryPath">解压路径</param>
public static bool UnTar(string filePath,string directoryPath)
{
    bool bRet = false;
    try
    {
        string folderName = "";
        if (!Directory.Exists(directoryPath))
        {
            Directory.CreateDirectory(directoryPath);
        }
        ReaderOptions options = new ReaderOptions();
        //解决中文乱码问题
        options.ArchiveEncoding.Default = Encoding.GetEncoding("utf-8");
        ExtractionOptions extract = new ExtractionOptions { ExtractFullPath = true, Overwrite = true };
        using (Stream stream = File.OpenRead(filePath))
        {
            var reader = ReaderFactory.Open(stream);
            while (reader.MoveToNextEntry())
            {
                if (!reader.Entry.IsDirectory)
                {
                    if (!string.IsNullOrEmpty(reader.Entry.Key) && reader.Entry.Size == 0 && (reader.Entry.Key.EndsWith("/") || reader.Entry.Key.EndsWith("\\")))
                    {
                        //过滤文件夹
                        continue;
                    }
                    reader.WriteEntryToDirectory(directoryPath, extract);
                }
            }
            bRet = true;
        }
    }
    catch (Exception ex)
    {
    }
    return bRet;
}
