一个加密解密的类，我在WEB里好用，到了WINFORM里不好用，大家给看下（急）

private static byte[] Keys
public static string EncryptDES
byte和string 报错，说应输入 class、delegate、enum、interface 或 struct F:\wjq\wodediyigchuangtishiyan\wodediyigchuangtishiyan\Security.cs 12 27 wodediyigchuangtishiyan

winform程序没有窗体？

[chazikai24]

你是不是要自己再窗体上加点控件？不然虽然上面代码能运行，但是没有调用你的加密解密的方法。

[sadan2121]

OK，解决，web类，和WINFORM类写法有细微差别，我没注意到。。
