1.核心代码:

 1 private static void IsUpdate(T old, T current, string id)
 2         {
 3             Model.PerFileHistory history = new Model.PerFileHistory();
 4             Model.Atrributes.ModifyFields atrr = null;
 5             Type type = typeof(T);
 6             PropertyInfo[] propertys = type.GetProperties();
 7             foreach (PropertyInfo property in propertys)
 8             {
 9                 if (property.PropertyType.IsValueType || property.PropertyType.Name == 'String')
10                 {
11                     if (property.PropertyType.FullName.Contains('Guid'))
12                         continue;
13                     //if (property.Name != 'CreateUserID' && property.Name != 'CreateTime' && property.Name != 'ModifyUserID' &&                                    property.Name != 'LastModifyTime')//排除这些字段不做判断
14                     //{
15                     if (property.GetCustomAttributes(typeof(Model.Atrributes.ModifyFields), false).Count() > 0)
16                     {
17                         object o1 = property.GetValue(old, null); //以前的值
18                         object o2 = property.GetValue(current, null); //修改后的值
19                         string str1 = o1 == null ? string.Empty : o1.ToString();
20                         string str2 = o2 == null ? string.Empty : o2.ToString();
21                         //判断两者是否相同,不同则插入历史表中
22                         if (str1 != str2)
23                         {
24                             history.BeforeValue = str1; //修改前的值
25                             history.AfterValue = str2; //修改后的值
26                             history.PCardNo = id; //修改数据的ID
27                             history.IPAddress = HanNeng.Common.GetClientIP.GetRealIP(); //获取当前用户的IP地址
28                             atrr = property.GetCustomAttributes(typeof(Model.Atrributes.ModifyFields), false)[0] as                    Model.Atrributes.ModifyFields;
29                             history.ModifyField = property.Name;  //修改的字段名称
30                             history.ModifyFieldName = atrr.FieldsName; //修改的字段中文名称
31 
32                             new BLL.PerFileHistory().AddModel(history);
33                         }
34                     }
35                     //}
36                 }
37             }
38         }

2.获取字段中文名,这个是在Model的类名里设置,示例如下:

 1 /// 
 2     /// 获取字段名称
 3     /// 
 4     public class ModifyFields : Attribute
 5     {
 6          public ModifyFields()
 7         {
 8         }
 9          public ModifyFields(string name)
10         {
11             this.FieldsName = name;
12         }
13         /// 
14         /// 修改的字段中文名
15         /// 
16          public string FieldsName
17         {
18             get;
19             set;
20         }
21     }

Model:Model类名示例

1          /// 
2         /// 科部
3         /// 
4         [Atrributes.ModifyFields('科部')]
5         public int? SubjectDep
6         {
7             set { _subjectdep = value; }
8             get { return _subjectdep; }
9         }

3.调用方式示例:

 1          if (id != null)
 2                 {
 3                     Model.PersonFile Person = bllPerson.GetModel(id);
 4                     if (modelPerson != null)
 5                     {
 6                         Model.Identity identity = Session['Identity'] as Model.Identity;
 7                         //if (identity.RoleIDs.ToString() == 'R01')  //如果是系统管理员,则不记录历史
 8                         //{
 9                         //对前后数据的不同进行比较
10                         Model.PersonFile OldPerson = Person;
11                         Model.PersonFile NewPerson = modelPerson;
12                         NewPerson.PersonAutoID = OldPerson.PersonAutoID;
13                         IsUpdate(OldPerson, NewPerson, id);
14                         //}
15                     }
16                 }

Controller.CS

  4.最终的效果图:

.NET MVC通过反射获取数据修改历史记录并插入数据表中_第1张图片
