.net使用自定义类属性实例

             get{return this._Type;}
        }
}
 
创建一个数据实体基类：

public class BaseEntity
{
        public BaseEntity()
        {
        }
 
         /// <summary>
        /// 获取表名称
        /// </summary>
        /// <returns></returns>
        public string GetTableName()
        {
            Type type = this.GetType();
            object[] objs = type.GetCustomAttributes(typeof(TableAttribute), true);
            if (objs.Length <= 0)
            {
                throw new Exception("实体类没有标识TableAttribute属性");
            }
            else
            {
                object obj = objs[0];
                TableAttribute ta = (TableAttribute)obj;
                return ta.TableName;                            //获取表名称
            }
        }
        /// <summary>
        /// 获取数据实体类上的FieldAttribute
        /// </summary>
        /// <param name="propertyName"></param>
        /// <returns></returns>
        public FieldAttribute GetFieldAttribute(string propertyName)
        {
            PropertyInfo field = this.GetType().GetProperty(propertyName);
