推荐答案

我们不能，不是真的 - 我们不知道你的技能，能力或兴趣，我们根本不知道你的课程会被接受的东西！



和你的导师交谈！他至少可以让你对预期的面积和尺寸有所了解，然后你可以专注于找到适合你感兴趣的参数。



回答错误的问题！ ：doh：

We can't, not really - we have no idea of your skills, abilities, or interests, and we definitely have no idea at all what would be considered acceptable by your course!

Talk to your tutor! he can at least give you some idea of areas and size expected, then you can focus on finding something within those parameters which fit what you are interested in.

Answered wrong question! :doh:

string strTest = GetUniqueKey();
strTest = "BCL/2009/" + strTest;
Response.Write(strTest);

此代码试图附加一个从函数获取的唯一键GetUniqueKey（）字符串 BCL / 2009 / 。



和 GetUniqueKey （），阅读 RNGCryptoServiceProvider类 [ ^ ]。另请查看 C＃RNGCryptoServiceProvider [ ^ ]。



如果您在Google中搜索，您可以获得许多其他有用的文章。

This code is trying to append one Unique Key got from function GetUniqueKey() with string BCL/2009/.

And for the GetUniqueKey(), read about RNGCryptoServiceProvider Class[^]. Also check C# RNGCryptoServiceProvider[^].

You can get many other useful articles, if you search in Google.
