C# 正則表達式數據注釋未檢測到結束行

Question

我想要這個正則表達式在我的 model 檢查結束行“-AR”或“-UY”但不工作

[StringLength(30, ErrorMessage = "The field must have between {2} y {1} characters", MinimumLength = 3)]
[RegularExpression(@"(-AR$)|{-UY$}", ErrorMessage = "Must have the regional parameter. Argentina:'-AR' ,Uruguay:'-UY'")]
public string Key { get; set; }

任何想法？

Answer 1

也許，用()替換{} ？

[RegularExpression(@"(-AR$)|(-UY$)", ErrorMessage = "Must have the regional parameter. Argentina:'-AR' ,Uruguay:'-UY'")]
