我收到以下错误:
An attribute argument must be a constant expression, typeof expression or array creation expression of an attribute parameter type
有什么想法吗?
您可以为此构建一个自定义属性,就像RangeYearToCurrent您指定当前年份一样
public class RangeYearToCurrent : RangeAttribute
{
public RangYearToCurrent(int from)
: base(typeof(int), from, DateTime.Today.Year) { }
}
