注册算法 MD5

这是一个标准的MD5函数吗？这是某人在注册算法用到的C#函数。本人不懂C#，没法测试其运行结果，在将其对比查看VB的MD5函数时，总觉得它有问题。

如：
obj15 = (short) 7;
object ac = -680876936;
md5_ff(ref obj2, ref obj4, ref obj6, ref obj8, ref objArray, ref obj15, ref ac);
这是第一轮循环的一次：ref obj15，ref ac就好像与正常的不一样！应该是ref ac，ref obj15。
作者是不是对MD5函数修改了，运行结果是非标准的MD5了？？ 我在VB的对应位置把这两个调换一下，VB 中报错。

作者软件中的C#的MD5函数如下：

public static string md5(ref string smessage)

另：

{
   goto Label_0050;
}

我把StringType.FromInteger((IntegerType.FromString(ModRegister.gstrZhucema) ^ 0x4294bf) + 0x173fe5)
在VB中直接转换为：
AA = Val(funcGetZhucema(Text1.Text)) Xor 4363455    （4363455是0x4294bf转的十进制，直接用Xor 0x4294bf出错，所以转换了）
Text2.Text = AA + 1523685                         （1523685是0x173fe5转的十进制，直接用Xor 0x173fe5出错，所以转换了）
对吗？？
最后运行出的结果与原软件有出入？？总不对。。

MD5算法有标准的，还有非标的，有的软件采用非标准的MD5验证，所以要看好是不是标准的MD5才行。

谢谢2楼回复，能帮看一下吗？确认是不是标准的MD5？如果不是怎么把其转换为对应的VB代码。就应该不麻烦吧。如果看懂。我可以把VB的MD5函数贴上来。对比看。

编译一下，与常规的计算器对比一下结果就知道标不标了

问题是我编译时，总出错。。。对C#不太了解。。。
