 private void CopyFile(string srcFile, string destDir)
        {
            DirectoryInfo destDirectory = new DirectoryInfo(destDir);
            string fileName = Path.GetFileName(srcFile);
            if (!File.Exists(srcFile))
            {
                return;
            }

            if (!destDirectory.Exists)
            {
                destDirectory.Create();
            }

压缩文件 引用using Ionic.Zip

 using (ZipFile zip = new ZipFile(System.Text.Encoding.Default))
                {
                    zip.AddDirectory(FilePath);
                    zip.Save(FilePath + ".zip");
                }
