C＃RegEx匹配模式完全正确

Question

I'm wanting to match a string exactly, for instance I have two expressions that I want to match independent of each other. Expressions are

/SignUpFor

/SignUpFor/ThankYou

The string "/SignUpFor" returns a match on the first expression which is correct; the string "/SignUpFor/ThankYou" returns a match on both.

How can I get "SignUpFor/ThankYou" just to match with the expression /SignUpFor/ThankYou .

The reason I'm not just using "==" is that I have other expressions such as /TheLovelyBlog/Entry/([0-9]+)

These expression are stored in a database.

Answer 1

把^放在开头，把$放到最后http://msdn.microsoft.com/en-us/library/h5181w5w.aspx

Answer 2

在表达式的开头和结尾添加^和$

Answer 3

If you start a regex with ^ , then the match must be from the start. End the regex with $ to signal that the match must be until the end.
