第一步创建元数据类

1 using System; 2 using System.Collections.Generic; 3 using System.Linq; 4 using System.Reflection; 5 using System.Web; 6 using System.Web.Mvc; 7  8 namespace MvcApplication19 9 {10     [AttributeUsage(AttributeTargets.Class | AttributeTargets.Property)]11     public class DisplayTextAttribute : Attribute, IMetadataAware12     {13         private static Type staticResourceType;14         public string DisplayName { get; set; }15         public Type ResourceType { get; set; }16 17         public DisplayTextAttribute()18         {19             this.ResourceType = staticResourceType;20         }21 22         public void OnMetadataCreated(ModelMetadata metadata)23         {24             this.DisplayName = this.DisplayName ?? (metadata.PropertyName ?? metadata.ModelType.Name);25             if (null == this.ResourceType)26             {27                 metadata.DisplayName = this.DisplayName;28                 return;29             }30             PropertyInfo property = this.ResourceType.GetProperty(this.DisplayName, BindingFlags.NonPublic | BindingFlags.Public | BindingFlags.Static);31             metadata.DisplayName = property.GetValue(null, null).ToString();32         }33 34         public static void SetResourceType(Type resourceType)35         {36             staticResourceType = resourceType;37         }38     }39 }

第二步创建Person类

1 using System; 2 using System.Collections.Generic; 3 using System.Linq; 4 using System.Web; 5  6 namespace MvcApplication19.Models 7 { 8     public class Person 9     {10         [DisplayText]11         public string  Name { get; set; }12 13          [DisplayText]14         public string Sex { get; set; }15 16          [DisplayText]17         public string BirthDay { get; set; }18          [DisplayText]19         public string Dep { get; set; }20     }21 }
