Question

Hi is it possible using Entity Framework and/or linq to select a certain number of rows? For example i want to select rows 0 – 500000 and assign these records to the List VariableAList object, then select rows 500001 – 1000000 and assign this to the List VariableBList object, etc. etc.

Where the Numbers object is like ID,Number,DateCreated, DateAssigned, etc.

Answer 1

Sounds like you’re looking for the .Take(int) and .Skip(int) methods

using (YourEntities db = new YourEntities())
{
    var VariableAList = db.Numbers
        .Take(500000);

    var VariableBList = db.Numbers
        .Skip(500000)
        .Take(500000);
}

You may want to be wary of the size of these lists in memory.

Note: You also may need an .OrderBy clause prior to using .Skip or .Take–I vaguely remember running into this problem in the past.
