推荐答案
如果您正在谈论DataTable中的自动编号字段,请查看以下内容:http://msdn.microsoft.com/en-us/library/system.data.datacolumn.autoincrement.aspx [^ ].但是,您已经标记了MS-Access,因此,如果要在Access中具有自动编号字段,可以在Access的列上对其进行定义.
If you''re talking about an auto numbering field in a DataTable then have a look at this: http://msdn.microsoft.com/en-us/library/system.data.datacolumn.autoincrement.aspx[^]. However you have tagged MS-Access so if you want to have an auto numbering field in Access you can define it on an column in Access.
