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

/// <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;
