如何使用 DisplayName 检索 属性 名称？

Question

public class DoctorInfo    
{
     [DisplayName("form1[0].P1[0].Physician-Name[0]")]
     public string ProviderFullName { get; set; }
}

如果我手头有 DisplayName，如何以编程方式获取 属性 名称 "ProviderFullName"？

Answer 1

鉴于 DisplayName 你可以 get all the PropertyInfo members in the class, then iterate over those to see if any of those has a DisplayName attribute using MemberInfo.GetCustomAttributes.

如果 DisplayName 匹配，则使用 MemberInfo.Name property 取回名称。

您可以迭代属性和自定义属性 -

 PropertyInfo[] properties = typeof(DoctorInfo).GetProperties();
            foreach (PropertyInfo prop in properties)
            {
                object[] attrs = prop.GetCustomAttributes(true);

                foreach (object attr in attrs)
                {
                    DisplayNameAttribute displayName = attr as DisplayNameAttribute;
                    if (displayName != null)
                    {
                       var attributeName = displayName.DisplayName; // check if this matches what you want
                    string propertyName = prop.Name;                        }
                }
            }
