C＃中带有特殊字符的手机号码正则表达式

Question

I'm trying to build a regular expression to validate mobile numbers that accepts () , - and + . I am totally new to this and this is what I could build

\+?\(?([0-9])\)?[- ]?\(?([0-9])\)?

But I know this wrong since it is accepting data such as 123456- which is not right. Can somebody please help me build a regex so that itdoes not accept inputs like

123)3575
12349-
-2345678

There is no limit to the number of digits entered. I'm expecting it to accept inputs of type

(123)4567-67898
+234567890
1234-4567-67

Please help..

Something like

/^(\+|\(\d+\))?\d+(-\d+)*$/
