在 FluentValidation 中忽略大小写敏感

Question

Anyone have any ideas to ignore case in FluentValidation

Example RuleFor(x => x.Gender).Ignorecase(); so user would able to enter F or f .

Answer 1

你能做到以下几点吗？

RuleFor(x.ToLower() => x.Gender.ToLower());

Answer 2

I think built-in Regex validation will do the work: https://github.com/JeremySkinner/FluentValidation/wiki/c.-Built-In-Validators#regular-expression-validator

Somethink like:

RuleFor(x => x.Gender).Matches("^[FfMm]{1}$");

Answer 3

It is possible by create an Extension method

public static bool EqualsIgnoreCase(this string from, string to)
 { 
   return string.Equals(from, to, StringComparison.OrdinalIgnoreCase); 
 }

then use it like bellow:

RuleFor(x => x.Gender.EqualsIgnoreCase("f"))

Answer 4

平等验证器支持这一点：

RuleFor(x => x.Gender).Equal("f", StringComparer.OrdinalIgnoreCase);
