Question

Have a Linq query as following which works:

from row in myDataTable.AsEnumerable() select row.Field<string>("myDataColumn")

Now try to make it work with any column data type (not just string). Tried the following:

from row in myDataTable.AsEnumerable() select row.Field<myDataTable.Columns["myDataColumn"].DataType>("myDataColumn")

But it doesn’t work.

So is there a way to make the data type dynamic in this particular Linq query?

Answer 1

The Field property is designed for getting the value when you know the type at compile time. When you don’t just use the indexer:

from row in myDataTable.AsEnumerable() select row["myDataColumn"];

This will return the value as an object.
