Mvc validation regular expression only numbers?
提问by Neo
I tried the following code for digits-only validation for a contact number validation in Mvc web app.
我在 Mvc Web 应用程序中尝试了以下代码，用于仅数字验证的联系人号码验证。
[RegularExpression(@"/(^\(\d{10})?)$/", ErrorMessage = "Please enter proper contact details.")]
[Required]
[Display(Name = "Contact No")]
public string ContactNo { get; set; }
But the validation expression is not working.
但是验证表达式不起作用。
For the contact number I want to only accept digits. It can be either a 10 digit mobile number or a land-line number.
对于联系电话，我只想接受数字。它可以是 10 位手机号码或固定电话号码。

/ /is javascript way to build a regular expression literal object. In .NET you should not use it.
/ /是 javascript 构建正则表达式文字对象的方法。在 .NET 中你不应该使用它。
Try the following:
请尝试以下操作：
@"^\((\d{10}?)\)$"
or if you want exactly 10 digits:
或者如果你想要正好 10 位数字：
@"^(\d{10})$"

If don't have any restrictions other than numbers only, this should fit:
如果除了数字之外没有任何限制，这应该适合：
[RegularExpression(@"^\d+$", ErrorMessage = "Please enter proper contact details.")]
[Required]
[Display(Name = "Contact No")]
public string ContactNo { get; set; }

This worked for me:
这对我有用：
[RegularExpression(@"^[0-9]{10}", ErrorMessage = "Please enter proper contact details.")]
