选择方案：  
使用SharpCompress框架  
1.下载SharpCompress.dll并引用  
2.编写代码：

using SharpCompress.Reader;
    using System;
    using System.Collections.Generic;
    using System.IO;
    using System.Linq;
    using System.Text;
    using System.Threading.Tasks;
    
    namespace TestUnzip
    {
        class Program
        {
            static void Main(string[] args)
            {
                using (Stream stream = File.OpenRead(@"F:\TestUnZip\testUnzip.rar"))
                {
                    var reader = ReaderFactory.Open(stream);
                    while (reader.MoveToNextEntry())
                    {
                        if (!reader.Entry.IsDirectory)
                        {
                            Console.WriteLine(reader.Entry.FilePath);
                            reader.WriteEntryToDirectory(@"F:\TestUnZip");
                        }
                    }
                }
            }
        }
    }

补充：  
.net 4.5以后集成到框架内的内容

/// <summary>
            /// 解压缩文件到指定目录，将在指定目录下解压出一个压缩文件名字的最终的目录
            /// </summary>
            /// <param name="ZipPath">ZIP文件路径</param>
            /// <param name="ExtractPath">要解压缩的目录</param>
            private void UnZipFile(string ZipPath,string ExtractPath)
            {
                //string NewFile = @"c:\users\exampleuser\NewFile.txt";
                if (System.IO.File.Exists(ZipPath))
                {
                    using (ZipArchive Archive = ZipFile.Open(ZipPath, ZipArchiveMode.Update))
                    {
                        //Archive.CreateEntryFromFile(NewFile, "NewEntry.txt");
                        //如果目录下面有文件，将解压缩失败，所以之前先备份目录
                        Archive.ExtractToDirectory(ExtractPath);
                    }
                }
    
            }
