Try this

C#

where table.id == tempIdValue
select new { Id = table.Id, Name = table.Name };

I havent tested this. Hope this works.

I you want to select all values as you said in SQL query is

select * from Table1

for this you can write like:

var result = Table1.AsEnumerable().ToList();

If you want to select values specific to some ID (here I have given 1, you can give any value) you can write like:

var result1 = (from r in Table1.AsEnumerable()
                              where r.Field<int32>("ID")==1
                              select r).ToList();
