我有一个这样的字符串:
"(33) 3669-0210 Gerencia"
我试图获得所有数字后/之前 - (连字符) 直到找到两个端的白色空间 使用 Regex 在 C # 中 。
产出应
"3669-0210"
是否有人能帮助 Regex 表达式在 C # 中有效?
您可以使用此表达式 :
d+-d+
它是一个非捕获字词边界 < /em > 代号,后面是一个或多个数字,后面是连字符、一个或数个数字,最后是另一个非捕获字边界。
如果匹配的数字总是4位数长,则更准确:
d{4}-d{4}
"[0-9]+-[0-9]+" 这应该够了
解释:
[0-9]/code> - 至少一个数字
- -连字符
[0-9]/code> - 至少一个数字
您可以使用此表达式 :
S+-S+
它为一个或多个非白色空间字符,然后是连字符,然后是一个或多个非白色空间字符。
