代码生成器，生成MODEM是出现“？”号
我在用代码生成器，链接Oracle数据库时，生成MODEL层是，出现了多余的“？”
如下:
#region Model
private int _templetid;
private string _templetname;
private string _shortname;
private string _chinacode;
private int? _sortorder;
private int? _isuse;
.............
/// <summary>
///
/// </summary>
public int? SORTORDER
{
set{ _sortorder=value;}
get{return _sortorder;}
}
/// <summary>
///
/// </summary>
public int? ISUSE
{
set{ _isuse=value;}
get{return _isuse;}
}
#endregion Model
