Suppose your table has the following columns: ID, Col1, Col2, Col3, Col4. You can the use the following Linq statement.

bool anyIsNull = (from row in context.Table
                  where row.ID = id
                  select (row.Col1 == null || row.Col2 == null ||
                          row.Col3 == null || row.Col4 == null).Single();
