• .NET MVC通过反射获取数据修


    .NET MVC通过反射获取数据修

    折磨了我一个晚上的问题,奈何对物理的反射印象太深了,整天去想着物理的反射、折射怎么解。感谢少将哥哥给我的指点,经过一个晚上对反射的恶补,最终搞定了。纪念一下。

      1.核心代码:

    private static void IsUpdate<T>(T old, T current, string id)
    {
    Model.PerFileHistory history = new Model.PerFileHistory();
    Model.Atrributes.ModifyFields atrr = null;
    Type type = typeof(T);
    PropertyInfo[] propertys = type.GetProperties();
    foreach (PropertyInfo property in propertys)
    {
    if (property.PropertyType.IsValueType || property.PropertyType.Name == "String")
    {
    if (property.PropertyType.FullName.Contains("Guid"))
    continue;
    //if (property.Name != "CreateUserID" && property.Name != "CreateTime" && property.Name != "ModifyUserID" && property.Name != "LastModifyTime")//排除这些字段不做判断
    //{
    if (property.GetCustomAttributes(typeof(Model.Atrributes.ModifyFields), false).Count() > 0)
    {
    object o1 = property.GetValue(old, null); //以前的值
    object o2 = property.GetValue(current, null); //修改后的值
    string str1 = o1 == null ? string.Empty : o1.ToString();
    string str2 = o2 == null ? string.Empty : o2.ToString();
    //判断两者是否相同,不同则插入历史表中
    if (str1 != str2)
    {
    history.BeforeValue = str1; //修改前的值
    history.AfterValue = str2; //修改后的值
    history.PCardNo = id; //修改数据的ID
    history.IPAddress = HanNeng.Common.GetClientIP.GetRealIP(); //获取当前用户的IP地址
    atrr = property.GetCustomAttributes(typeof(Model.Atrributes.ModifyFields), false)[0] as Model.Atrributes.ModifyFields;
    history.ModifyField = property.Name; //修改的字段名称
    history.ModifyFieldName = atrr.FieldsName; //修改的字段中文名称

    new BLL.PerFileHistory().AddModel(history);
    }
    }
    //}
    }
    }
    }

    复制代码
     1 private static void IsUpdate<T>(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         }
    复制代码

      2.获取字段中文名,这个是在Model的类名里设置,示例如下:

    /// <summary>
    /// 获取字段名称
    /// </summary>
    public class ModifyFields : Attribute
    {
    public ModifyFields()
    {
    }
    public ModifyFields(string name)
    {
    this.FieldsName = name;
    }
    /// <summary>
    /// 修改的字段中文名
    /// </summary>
    public string FieldsName
    {
    get;
    set;
    }
    }

    Model

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

    /// <summary>
    /// 科部
    /// </summary>
    [Atrributes.ModifyFields("科部")]
    public int? SubjectDep
    {
    set { _subjectdep = value; }
    get { return _subjectdep; }
    }

    Model类名示例

    复制代码
    1          /// <summary>
    2         /// 科部
    3         /// </summary>
    4         [Atrributes.ModifyFields("科部")]
    5         public int? SubjectDep
    6         {
    7             set { _subjectdep = value; }
    8             get { return _subjectdep; }
    9         }
    复制代码

      3.调用方式示例:

    if (id != null)
    {
    Model.PersonFile Person = bllPerson.GetModel<Model.PersonFile>(id);
    if (modelPerson != null)
    {
    Model.Identity identity = Session["Identity"] as Model.Identity;
    //if (identity.RoleIDs.ToString() == "R01") //如果是系统管理员,则不记录历史
    //{
    //对前后数据的不同进行比较
    Model.PersonFile OldPerson = Person;
    Model.PersonFile NewPerson = modelPerson;
    NewPerson.PersonAutoID = OldPerson.PersonAutoID;
    IsUpdate(OldPerson, NewPerson, id);
    //}
    }
    }

    Controller.CS

    复制代码
     1          if (id != null)
     2                 {
     3                     Model.PersonFile Person = bllPerson.GetModel<Model.PersonFile>(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                 }
    复制代码

      4.最终的效果图:

     
     

    JQuery结合Ajax实现双击Table表格,使Table变成可编辑,并保存到数据库中

     

          近期在做项目时,要实现通过双击Table表格的TR,使Table行变成可编辑,来实现修改数据并保存到数据库中的功能,无需多说,直接贴代码吧。希望能得到各位同仁指正。
