普通防爆pression匹配的IP地址+通配符

问题描述：

我试图用一个Regularex pressionValidator匹配的IP地址（可能通配符）对IP过滤系统。

I'm trying to use a RegularexpressionValidator to match an IP address (with possible wildcards) for an IP filtering system.

我用正则表达式如下：

"([0-9]{1,3}\\.|\\*\\.){3}([0-9]{1,3}|\\*){1}"

在LINQPad与Regex.Matches运行时，它工作正常，但似乎并没有当我使用的验证工作。

Which works fine when running it in LINQPad with Regex.Matches, but doesn't seem to work when I'm using the validator.

有没有人有一个建议，作为到一个更好的正则表达式或为什么它会在测试工作，但不是在原地？

Does anyone have a suggestion as to either a better Regex or why it would work in test but not in situ?

干杯，埃德

ASP：RegularEx pressionValidator 不要求你仔细逃跑反斜杠。你应该尝试：

asp:RegularExpressionValidator does not require you to double-escape backslashes. You should try:

（[0-9] {1,3} \\ |。\\ * \\）{3}（[0-9] {1,3} | \\ *）{1}
