在我的申请中,我需要一种简单的方式来坚持和篡改一套扼制的鞋子。 我认为,有两名实习生的《数据GridView》能够帮助我观看和编辑,我希望利用应用环境而不是数据库储存数据(可能是一种数据Set)。 我可以把这一切放在一起。 是否有办法?
What is the use of default keyword in C#? Is it introduced in C# 3.0 ?

这里我是如何这样做的。 MyMap等值奶制品。 他们必须是财产,因为DatGridView与田间做工。 MyMapCollection拥有MyMaps, 即BileList(在数据GridView中增加一行)。 这门课是为了使演播室视觉环境编辑高兴,使演播室与便衣主义者合作。 因此:
public class MyMap {
public String FirstField { get; set; }
public String SecondField { get; set; }
}
public class MyMapCollection : BindingList<MyMap>
{
public MyMapCollection Clone()
{
MyMapCollection result = new MyMapCollection();
foreach (MyMap map in this)
result.Add(new MyMap() {
FirstField = map.FirstField, SecondField = map.SecondField });
return result;
}
}
功能衣物造就了该物体的深度拷贝,因此,在环境中不会直接改变该物体的数据。 缺省,但当用户说的话。 在主编中,你将增加一个叫做“TheValues”的MyMapCollection项目,并在法典中使用非常简单的内容:
myDataGridView.DataSource = Settings.Default.TheValues.Clone();
如果数据应改成环境(当用户点点科索沃时),则相应改变环境:
Settings.Default.TheValues = (MyMapCollection)myDataGridView.DataSource;
利用数据或数据Set而不是MyMapCollection也是可能的,但这一解决办法允许我使用。 法典的其余部分甚至比数据单更加贴切。
如果你试图洗衣的价值观是显而易见的关键价值,那么你可以创造一种将这些价值作为特性的等级,并将这一类别物体编为XML档案。 您可以将这一类别降级,并将价值分配给数据GridView。
你们还可以创建一种习俗组合,将其与App.config/Web.config文档分开存放。 这与NHibernate或春天类似。 净配置文件存放在汇辑钥匙中。
