Canadian postal code validation
提问by Jimmy
I need to validate a Canadian postal code (for example, M4B 1C7) using C# (.NET) regular expressions.
我需要M4B 1C7使用 C# (.NET) 正则表达式验证加拿大邮政编码（例如，）。
采纳答案by Gordon Gustafson
Canadian postal codes can't contain the letters D, F, I, O, Q, or U, and cannot start with W or Z:
加拿大邮政编码不能包含字母 D、F、I、O、Q 或 U，并且不能以 W 或 Z 开头：
[ABCEGHJKLMNPRSTVXY][0-9][ABCEGHJKLMNPRSTVWXYZ][0-9][ABCEGHJKLMNPRSTVWXYZ][0-9]
If you want an optional space in the middle:
如果你想在中间有一个可选的空间：
[ABCEGHJKLMNPRSTVXY][0-9][ABCEGHJKLMNPRSTVWXYZ] ?[0-9][ABCEGHJKLMNPRSTVWXYZ][0-9]
回答by Templar
I suggest the following:
我建议如下：
bool FoundMatch = false;
try {
FoundMatch = Regex.IsMatch(SubjectString, "\A[ABCEGHJKLMNPRSTVXY]\d[A-Z] ?\d[A-Z]\d\z");
} catch (ArgumentException ex) {
// Syntax error in the regular expression
}
回答by Colin Mackay
Something like this:
像这样的东西：
^[A-Z]\d[A-Z] \d[A-Z]\d$

Validating the format of a postal code without validating its meaning isn't worth it, since typos can still result in a valid postal code for the wrong address. You want to validate the code against the address database. See http://www.canadapost.ca/cpo/mc/business/productsservices/atoz/postalcodeproducts.jsf
在不验证其含义的情况下验证邮政编码的格式是不值得的，因为拼写错误仍然可能导致错误地址的有效邮政编码。您想根据地址数据库验证代码。见http://www.canadapost.ca/cpo/mc/business/productsservices/atoz/postalcodeproducts.jsf

Here are the rules http://en.wikipedia.org/wiki/Postal_code#Reserved_characters
以下是规则http://en.wikipedia.org/wiki/Postal_code#Reserved_characters
ABCEGHJKLMNPRSTVXY <-- letter used
DFIOQU <-- letters not used because it mixes up the reader
WZ <-- letters used but not in the first letter
With that in mind the following in the proper regex
@[ABCEGHJKLMNPRSTVXY][0-9][ABCEGHJKLMNPRSTVWXYZ][\s][0-9][ABCEGHJKLMNPRSTVWXYZ][0-9]

Try this:
尝试这个：
function postalCodeCheck (postalCode, type) {
if (!postalCode) {
return null;
}
postalCode = postalCode.toString().trim();
var us = new RegExp("^\d{5}(-{0,1}\d{4})?$");
// var ca = new RegExp(/^((?!.*[DFIOQU])[A-VXY][0-9][A-Z])|(?!.*[DFIOQU])[A-VXY][0-9][A-Z]\ ?[0-9][A-Z][0-9]$/i);
var ca = new RegExp(/^[ABCEGHJKLMNPRSTVXY]\d[ABCEGHJKLMNPRSTVWXYZ]( )?\d[ABCEGHJKLMNPRSTVWXYZ]\d$/i);
if(type == "us"){
if (us.test(postalCode.toString())) {
console.log(postalCode);
return postalCode;
}
}
if(type == "ca")
{
if (ca.test(postalCode.toString())) {
console.log(postalCode);
return postalCode;
}
}
return null;
}
