MVC模型属性中的多行正则表达式

…我不擅长正则表达式。

我试图写一个正则表达式，将匹配一个或多个有效Guids在。net中，由新行字符分隔，在MVC模型中使用。

这是模型属性，正如我现在所拥有的:

[Required]
[Editable(true)]
[DataType(DataType.MultilineText)]
[Display(Name = "Audit Result Global Ids")]
[RegularExpression(@"^('{){0,1}[0-9a-fA-F]{8}'-[0-9a-fA-F]{4}'-[0-9a-fA-F]{4}'-[0-9a-fA-F]{4}'-[0-9a-fA-F]{12}('}){0,1}$", ErrorMessage = "Audit Result Global Ids must be a list of one or more valid GUIDs.")]
public List<Guid> AuditResultGlobalIds { get; set; }

这是我正在尝试匹配的示例。

C835EFF5-65D8-4F1B-824D-CD3FD1A04D77
A1FEFACA-6130-4E0A-BAC2-F101C2F4554C
ACD3D3FC-E841-45E9-A081-C113231E56EF

对于一个RegEx，我有一个很好的模式:

@"^('{){0,1}[0-9a-fA-F]{8}'-[0-9a-fA-F]{4}'-[0-9a-fA-F]{4}'-[0-9a-fA-F]{4}'-[0-9a-fA-F]{12}('}){0,1}$"

我只需要多行部分。

UPDATE:这是我最终使用的确切解决方案。

自定义验证类:

using System.Linq;
using System.Text.RegularExpressions;
/// <summary>
/// The regular expression on list elements.
/// </summary>
public class RegularExpressionOnListElements : RegularExpressionAttribute

    public RegularExpressionOnListElements(string pattern)
        : base(pattern)
    {
    }

    /// </returns>
    protected override ValidationResult IsValid(object value, ValidationContext validationContext)
    {
        if (value != null)
        {
            string[] lines = Regex.Split(value.ToString(), "'r'n");
            if (lines.Length > 0)
            {
                if (!lines.All(elem => base.IsValid(elem)))
                {
                    return new ValidationResult(
                        "Audit Result Global Ids must be a list of one or more valid GUIDs.");
                }
            }
        }
        return ValidationResult.Success;
    }
    #endregion
}
