System.OutOfMemoryException thrown for large table in EF

Question

This may be a simple or rapidly asked question.

In my EF application I am getting an exception.

System.OutOfMemoryException: Exception of type 'System.OutOfMemoryException' was thrown.

I am trying to retrieve records form Log table based on the idList (int) . Logs table has millions of records. How to fix this exception or how to optimize the code to solve this?

    var resultList = idList.Join(clientEntities.Logs,
                                 x => x,
                                 s => s.ID,
                                 (x, s) => s)

    foreach (var r in resultList)
    {
        ...
    }

Exception was thrown while executing the loop.

我认为最好的选择是使用分页。您可以通过使用分页来限制记录。
