通过反射获取对象属性及特征

定义特征类

实体类

        [EnitityMapping(ColumnName = "排序号", DataType = "System.Decimal")]
        public Decimal? sort_order {get;set;}
       
        
    }
}

反射

  public void fsmodel(object o)
        {
            string table = string.Empty;
            Type t = o.GetType();
            table = t.Name;
            object[] objs = t.GetCustomAttributes(typeof(EnitityMappingAttribute), true);
            foreach (object obj in objs)
            {
                EnitityMappingAttribute attr = obj as EnitityMappingAttribute;
                if (attr != null)
                {
                    table = table + " " +attr.TableName;//表名只有获取一次 
                    break;
                }
            }
            System.Reflection.PropertyInfo[] ps = t.GetProperties();
            foreach (System.Reflection.PropertyInfo pi in ps)
            {

                string aa = string.Empty;
                object[] objAttrs = pi.GetCustomAttributes(typeof(EnitityMappingAttribute), true);
                if (objAttrs.Length > 0)
                {
                    EnitityMappingAttribute attr = objAttrs[0] as EnitityMappingAttribute;
                    if (attr != null)
                    {
                        aa=" " + attr.ColumnName + " " + attr.DataType; //列名 
                    }
                }
                aa =aa + " " +  pi.Name + " " + pi.GetValue(o, null) + "\n";
                this.textBox1.AppendText(table + aa );
            }
           
          

        }

调用

 Model_T_BAS_AUTHORITY m = new Model_T_BAS_AUTHORITY();
            m.bas_authority_code = "112233";
            m.bas_authority_name = "334455";
            m.sort_order = 1;

            fsmodel(m);
