 上面是实体类的定义。在给DataGridView绑定了上面的实体作为数据源之后，DisplayAttribute标记的中文列名没有显示出来。为什么呢？

实在没有办法，手动使用下面的办法解决了。

if (GridView1.Columns.Count > 0)                {                    var props = typeof(BulletinBoardFile).GetProperties();                    foreach (var p in props)                    {                        var colParaObj = (DisplayAttribute)p.GetCustomAttributes(typeof(DisplayAttribute), false).FirstOrDefault();                        if (colParaObj != null)                        {                            for (int i = 0; i < GridView1.Columns.Count; i++)                            {                                if (GridView1.Columns[i].HeaderText.Equals(p.Name))                                {                                    GridView1.Columns[i].HeaderText = colParaObj.Name;                                    break;                                }                            }                        }                    }                }
