I need to find a pattern that restricts the input of data. What I need it to restrict input to:
我需要找到一种限制数据输入的模式。我需要它来限制输入:
First character must be "S" Second character must be "S", "T", "W", "X" or "V" The next 6 must be numbers for 0 - 9 The last 2 can be any capital letter or any number 0 - 9
第一个字符必须是“S”第二个字符必须是“S”,“T”,“W”,“X”或“V”接下来的6个必须是0到9的数字。最后2个可以是任何大写字母或任何数字0 - 9
So my research led me to put this together.....
所以我的研究让我把它放在一起......
^[S][STWXV]/d{6}[A-Z0-9]{2}$
From what I read:
从我读到的:
[S] mean the capital letter S only [STWXV] means any one letter from this list /d{6} means 6 digits [A-Z0-9]{2} means any 2 characters A - Z or 0 - 9
[S]表示仅大写字母S [STWXV]表示此列表中的任何一个字母/ d {6}表示6位[A-Z0-9] {2}表示任意2个字符A - Z或0 - 9
I am not looking for a match anywhere in a string, i need the whole string to match this pattern.
我不是在字符串中的任何地方寻找匹配,我需要整个字符串来匹配这个模式。
So why does Regex.IsMatch("SX25536101", "^[S][STWXV]/d{6}[A-Z0-9]{2}$") return false?
那么为什么Regex.IsMatch(“SX25536101”,“^ [S] [STWXV] / d {6} [A-Z0-9] {2} $”)会返回false?
Ive obviously gone wrong somewhere but this is my first attempt at Regular Expressions and this makes no sense :(
我在某处显然出了问题,但这是我对正则表达式的第一次尝试,这没有任何意义:(

You need to use \d for digits:
您需要使用\ d表示数字:
Regex.IsMatch("SX25536101", @"^[S][STWXV]\d{6}[A-Z0-9]{2}$"); // true
NOTE: Here is nice Regular Expressions Cheat Sheet which can help you in future.
