解决方案
解决方案二：
你自己去查c#的des加解密功能
解决方案三：
base64的加密可能问题不大。des的加密，不知道算法差异有多大了。也看不到java的算法。
解决方案四：
N多转换
解决方案五：
C#的c#的des秘钥只能是八位的，但是这个java的是12位的
解决方案六：

哪个人告诉你c#的des秘钥只能是八位的，微软的DES.Key属性写的清清楚楚“此算法支持长度为64位的密钥。”
解决方案七：
用http://www.tangiblesoftwaresolutions.com/里的工具转换出来不行啊！

哪里看不到java的算法？有的啊，publicStringeCode(StringneedEncrypt){byte[]result=(byte[])null;try{CipherenCipher=Cipher.getInstance("DES");SecretKeykey=Key.loadKey();enCipher.init(1,key);result=enCipher.doFinal(needEncrypt.getBytes());BASE64Encoderb=newBASE64Encoder();ByteArrayOutputStreambos=newByteArrayOutputStream();b.encode(result,bos);result=bos.toByteArray();}catch(Exceptione){thrownewIllegalStateException("Systemdoesn'tsupportDESalgorithm.");}returnnewString(result);}publicStringdCode(byte[]result){Strings=null;try{CipherdeCipher=Cipher.getInstance("DES");deCipher.init(2,Key.loadKey());BASE64Decoderd=newBASE64Decoder();result=d.decodeBuffer(newString(result));byte[]strByte=deCipher.doFinal(result);s=newString(strByte);}catch(Exceptione){thrownewIllegalStateException("Systemdoesn'tsupportDESalgorithm.");}returns;}这两个就是加密和解密算法
解决方案九：
有人可以帮忙解决这个问题吗？感谢！
解决方案十：
CipherenCipher=Cipher.getInstance("DES");byte[]strByte=deCipher.doFinal(result);Cipher是java里的des加密算法，在C#里没有。你现在的代码里des加密是依靠这个类库实现的。你有Cipher的源码的话，可以考虑在C#里实现。
