Well, weird question. Not much of an info shared.

Since you asked on how to break a dataset into 16 tables, you would need to loop 16 times to get 92536 records from the dataset. Get them and store them in a separate table.

C#

for(int i=0; i<16 ; i++)
{ 
  // Create a datatable here: table[i]
  for(int j=0; j<92536; j++)
   {
      //Get data for row number [i*92536+j] of large dataset
      // insert these data in the table[i]
   }
}

Try!

Solution 1

C#

YourDataTable.Select()

gives you an array of Datarows.
If you use LINQ as below;

C#

myDataTable.Select(x => x).Take(100).ToEnumerable();

gives you the first 100 DataRows and

C#

myDataTable.Select(x => x).Skip(100).Take(100).ToEnumerable();

for the next 100.

Hope this helps :)

So many rows of data in memory.. I would avoid that.
