不允许带有 DataAnnotations 的特殊字符

Question

I have a string property in my ViewModel and I want to set that to don't allow some special characters as, :, *,?, ", <, > and |. How can I write a regular expression to do it?

Coul be correct [RegularExpression(@"^[^\/: <>?|;.)(]+$")]*?

Answer 1

There's a problem, what some special symbols are. If the complete list is

, :, *,?, ", <, > and |

then you can put it as

[RegularExpression(@"^[^,:*?""<>\|]*$")]

if, however, you want to exclude all punctuation ( , :, *, ?, " ) and math symbols ( <, >, | ), you can put

[RegularExpression(@"^[^\p{P}\p{Sm}]*$")]
