asp.net-mvc-5 - 更改消息 "Passwords must have at least one non letter or digit character."

Question

我正在使用 Asp.Net Identity PasswordValidator 并希望在更改此默认消息方面得到一些帮助，使其更加清晰。

例如，如何更改此消息并包含特殊字符？

 manager.PasswordValidator = new PasswordValidator
        {
            RequiredLength = 10,
            RequireNonLetterOrDigit = true,
            RequireDigit = true,
            RequireLowercase = true,
            RequireUppercase = true
        };

namespace YourNameSpace.IdentityExtensions
{
    public class CustomPasswordValidator : IIdentityValidator<string>
    {
        public int RequiredLength { get; set; }
        public CustomPasswordValidator(int length)
        {
            RequiredLength = length;
        }

        public Task<IdentityResult> ValidateAsync(string item)
        {
            if (String.IsNullOrEmpty(item) || item.Length < RequiredLength)
            {
                return Task.FromResult(IdentityResult.Failed(String.Format("Password should be of length {0}", RequiredLength)));
            }

            string pattern = @"^(?=.*[0-9])(?=.*[!@#$%^&*])[0-9a-zA-Z!@#$%^&*0-9]{10,}$";

            if (!Regex.IsMatch(item, pattern))
            {
                return Task.FromResult(IdentityResult.Failed("Password should have one numeral and one special character"));
            }

            return Task.FromResult(IdentityResult.Success);
        }
    }
}
