求大神把这小段java的代码转换成C#代码，感激不尽
此段java代码好像是用来加密的。可能会调用到其他的类，注明下就行了，
小弟在这里先谢谢了。
文件名 DES.java
由于类似定义数组定义值的重复代码太多发不出去。所以传到百度云上。

看来你一点也不懂java，估计你下都没下。
跟这个类似吧
public sealed class DESEncryption
{
private static readonly string encryptKey = "YJSERVER";
private static readonly string decryptKey = "YJSERVER";

补充：.NET技术 , C#
