[英]How to validate multiple phone number using regular expression
I have a scenario, where i have to validate multiple phone numbers at a time. 我有一种情况,我必须一次验证多个电话号码。 For example i will input phone number like this in the grid.
例如,我将在网格中输入这样的电话号码。
+46703897733;+46733457773;+46703443832;+42708513544;+91703213815;+919054400407. +46703897733; +46733457773; +46703443832; +42708513544; +91703213815; +919054400407。
Any one help me please? 有人可以帮我吗?
Thanks in advance. 提前致谢。
use below code for +46... numbers. 将以下代码用于+46 ...数字。 other number is simlar
其他数字类似
string regexPattern = @"^+46[0-9]{9}$";
Regex r = new Regex(regexPattern);
foreach(string s in numbers)
{
if (r.Match(s).Success)
{
Console.WriteLine("Match");
}
}
Iterate through your number collection and validate them one by one like: 遍历您的号码收集并逐个验证它们,例如:
Regex rgx = new Regex(yourPattern, RegexOptions.IgnoreCase); foreach(string num in numbers) { if(rgx.Matches(num )) //do something you need }
You also can add RegularExpressionValidator to your phone number column cells in grid and pass it your pattern. 您还可以将RegularExpressionValidator添加到网格中的电话号码列单元格,并将其传递给您的模式。 Then button click or any event that causes validation will do it for you.
然后单击按钮或任何导致验证的事件将为您完成。
if + is mandatory in your number than do this in c# 如果您的电话号码中的+号比C#中的号强
string[] numbers = new string[] { "+46703897733","+46733457773","46733457773"};
string regexPattern = @"^\+(\d[\d-. ]+)?(\([\d-. ]+\))?[\d-. ]+\d$";
Regex r = new Regex(regexPattern);
foreach(string s in numbers)
{
if (r.Match(s).Success)
{
//"+46703897733","+46733457773" are valid in this case
Console.WriteLine("Match");
}
}
if + is not mandatory you can do this 如果+不是必需的,则可以执行此操作
string regexPattern = @"^\+?(\d[\d-. ]+)?(\([\d-. ]+\))?[\d-. ]+\d$";
// all the numbers in the sample above will be considered as valid.
Your regular expression pattern should be then: 正则表达式模式应为:
[+][1-9][0-9]*
and this is as of you required; 这是您的要求; If you want to limit it, like to: +911234567890, then your exp should be:
如果您想限制它,例如:+911234567890,那么您的exp应该是:
[+][1-9][0-9]{11,11}
