Question

Match m = Regex.Match之后我没有输出。我认为它存在问题。有人可以检查代码，如果可以的话。

输入alarm_text如下：

Prio 1 WESTERSTRAAT 140 ENKHUIZEN Woning brand 4632 4651

我想要做的是将字符串分为四组：“Prio 1”，“WESTERSTRAAT 140 ENKHUIZEN”，“Woning brand”，“4632 4651”

Answer 1

问题在于您的第4组 - 没有[0-9]+或[0-9].*您的上一组缺少您的最后一个组：

Match m = Regex.Match(alarm_text, @"(.*\s)([A-Z]+.[0-9]+.[A-Z])(.*\s)([0-9].*\s[0-9]+)");

当然，这也取决于你最后一组中是否只有数字第二组中也有错误 - 没有+\s文本转到第3组 - 现在应该没问题

Match m = Regex.Match(alarm_text, @"(.*\s)([A-Z]+.[0-9]+.[A-Z]+\s)(.*\s)([0-9].*\s[0-9].*)");

让代码几乎正常工作。只有他正在采取平面价值文本。不是字符串

private static void databaseThis(string capcode, string melding, string korps)
        {
            Match m = Regex.Match(melding, @"(.*\s)([A-Z]+.[0-9]+.[A-Z]+\s)(.*\s)([0-9].*\s[0-9].*)");
            string preText = m.Groups[1].Value;
            string streetName = m.Groups[2].Value;
            string postText = m.Groups[3].Value;
            string cars = m.Groups[4].Value;

            string[] strArray = new string[] { "insert into alarmeringen2010(capcode, desc1, department, melding, alerting, data1, voertuigen)values('capcode','melding','korps','streetName','preText','postText','cars');" };
            string str = string.Concat(strArray);
          }

使用匹配正则表达式时没有输出
