我已将ComponentModel.DataAnnotations[Required] 属性用于验证消息。该消息未显示在我的表单中。但是，正则表达式验证和范围验证工作正常。
在我的一个领域中，我同时使用了 [Required] 和 [RegualarExpression]。当我在文本框中输入错误时，会出现 RegualarExpression 验证消息，在删除输入后，只有必需的验证消息。否则，不会出现必需的验证消息。
这是我的代码：
--模型类
public class Email
{
[Required(ErrorMessage = "Email Address is required!")]
[RegularExpression("^([a-zA-Z0-9_\\-\\.]+)@((\\[[0-9]{1,3}\\.[0-9]{1,3}\\.[0-9] {1,3}\\.)|(([a-zA-Z0-9\\-]+\\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\\]?)$", ErrorMessage = "Invalid Email Address.")]
public virtual string EmailAddress { get; set; }
[Required(AllowEmptyStrings = false, ErrorMessage = "First Name is Required")]
public virtual string FirstName { get; set; }
public virtual string MiddleName { get; set; }
[Required(ErrorMessage = "Last Name is required!")]
public virtual string LastName { get; set; }
public virtual string Status { get; set; }
}
