LINQ query on a DataTable

Question

I\'m trying to perform a LINQ query on a DataTable object and bizarrely I am finding that performing such queries on DataTables is not straightforward. For example:

Answer 1

I realize this has been answered a few times over, but just to offer another approach:

I like to use the .Cast() method, it helps me maintain sanity in seeing the explicit type defined and deep down I think .AsEnumerable() calls it anyways:

var results = from myRow in myDataTable.Rows.Cast() 
                  where myRow.Field("RowNo") == 1 select myRow;

or

var results = myDataTable.Rows.Cast()
                      .FirstOrDefault(x => x.Field("RowNo") == 1);

As noted in comments, no other assemblies needed as it's part of Linq (Reference)
