如果没有引用ICSharpCode.SharpZipLib包，可以通过工具-nuget包管理器-管理nuget包搜素，然后安装引用

下面直接上代码，为压缩zip代码 

/// 压缩成zip
        /// </summary>
        /// <param name="filesPath">d:\</param>
        /// <param name="zipFilePath">d:\a.zip</param>
        public static void CreateZipFile(string folderToZip, string zipedFile)
        { 
            bool result = false;
            if (!Directory.Exists(folderToZip))
                return ;

            ZipOutputStream zipStream = new ZipOutputStream(File.Create(zipedFile));
            zipStream.SetLevel(6);
            //if (!string.IsNullOrEmpty(password)) zipStream.Password = password;

            result = ZipDirectory(folderToZip, zipStream, "");

            zipStream.Finish();
            zipStream.Close();

            return ;

        }
