Remarks
This class enables you to query over the table and add, remove, and attach objects.
An application can access a Table<TEntity> instance via GetTable or by using a strongly typed property for the strongly typed DataContext. That is, when the designer generates a DataContext object, it generates properties to represent each Table. For example:
[global::System.Data.Linq.Mapping.DatabaseAttribute(Name="SignOffTool")]
public partial class DataClasses1DataContext : System.Data.Linq.DataContext
{
public System.Data.Linq.Table<User> Users
{
get
{
return this.GetTable<User>();
}
}
}
For this strongly typed DataContext, you can access the Users property to get Table<User>
.
