输入：  SNGenerator.RandomSNKGenerator.GetSerialKeyAlphaNumaric（SNGenerator.SNKeyLength.SN20，"Hello World"）;

Input : SNGenerator.RandomSNKGenerator.GetSerialKeyAlphaNumaric(SNGenerator.SNKeyLength.SN20, "Hello World");

输出：  B18D-0AB1-E064-4175-05B7

Output : B18D-0AB1-E064-4175-05B7

推荐答案

否，你将无法将其翻译成C.让我们认为：并不是说你不能翻译C＃代码本身，你可以通过一些努力来完成。问题是该代码中的大部分工作是由MD5类完成的，它是C＃可用的Framework类库的
部分。 C中没有这个课程。我不怀疑，如果你环顾四周，你可能会找到一些在C中计算MD5哈希的源代码，但它不再是翻译$的问题。 b $ b代码，但找到  另一个代码。

No, you will not be able to translate this into C. Let's qualify that: it's not that you can't translate the C# code itself, which you could do with some effort. The problem is that the bulk of the work in that code is done by the MD5 class, which is part of the Framework Class Library available to C#. This same class is not available in C. I don't doubt that if you look around you might be able to find some source code for computing an MD5 hash in C, but it is no longer a matter of translating the code, but of finding another piece of code.
