验证以留出电话号码空间

问题描述:

我的.net文本框中有一个验证,其中仅需要数字

i have a validation in my .net textbox where it will take only numbers

但是当我把电话格式设置为

but when i put the the phone format like

080 234234

080 234234

由于空格而无法接受

如何解决这个问题?

任何人都可以在正则表达式中提供帮助吗?

could anyone help in regular expression ?

当前表达是这个[0-9] +

Current expression is this [0-9]+

只需在字符范围内添加空格:

Simply add space to characters range:

[0-9][0-9 ]*

您还可以添加开始和停止指示器:

You can also add start and stop indicators:

^[0-9][0-9 ]*$

数字必须以数字开头,后跟数字或空格(零个或多个).

number must start with digit followed with digits or spaces (zero or more).
