yes this is possible

If we execute 2 select command either in stored procedure or in select command and then executereader method fired of command object. it return 2 tables in datareader.

like :
string str="Select * from a;select * from b";
cmd.commandtext=str;
dr=cmd.executereader();

Now it return 2 tables in datareader (dr).
