Question

I’m using LINQ to Get data from database table called table1
when using LINQ a class called table1 was created

i created a partial class to add functionality to table1 class

public partial class Table1
{
public Table1(int id)
{
    using (DBDataContext item = new DBDataContext())
        {
            var q = (from c in item.table1
                     where c.ID == id
                     select c).FirstOrDefault();
        }
}
}

now i want to assign the result “q” to the current object
do i need to assign it’s properties one by one ?
or is there something faster??

Answer 1

Yes you need to assign it property by property, cause the result of your query is not an object, but IEnumerable<..something..> of something. So you need to iterate over collection of values and assign them to corresponding properties of the object.

EDIT

At this point I would do, like this:

public static Table1 TableFromId(int Id)
{
     using (DBDataContext item = new DBDataContext())
        {
            return  (from c in item.table1
                     where c.ID == id
                     select c).FirstOrDefault() as Table1;
        }
}

and after use

Table1 table = Table1.TableFromId(0);
