Currently i am having some problems with getting some data out of a DataTable by selecting all rows, but only some columns.

To be a little more descriptive here is a little example:

### Sample Data

```
| ID | FirstName | LastName | Age |
+----+-----------+----------+-----+
|  1 | Alice     | Wannabe  | 22  |
|  2 | Bob       | Consumer | 27  |
|  3 | Carol     | Detector | 25  |

```

### What i have

So what we got from our GUI is a `IEnumerable<DataColumn> selectedColumns` and there we'll find two elements (*FirstName* and *LastName*).

Now i need some result which contains all rows, but only the above two columns (or any other *list* of selected columns).

So far i already used LINQ on several one dimensional objects, but this two dimensional object gives me a little headache.

```
// The hard-coded way
Table.AsEnumerable().Select(row => new { FirstName = row[1], LastName = row[2] });

// The flexible way
Table.AsEnumerable().Select(row => row ???)

```

But how can i now say, which columns from row should be selected by using my selectedColumns?
