c# - Best Practice: Convert LINQ Query result to a DataTable without looping

Question

What is the best practice to convert LINQ-Query result to a new DataTable?
can I find a solution better than foreach every result item?

EDIT AnonymousType

var rslt = from eisd in empsQuery
           join eng in getAllEmployees()
           on eisd.EMPLOYID.Trim() equals eng.EMPLOYID.Trim()
           select new
           {
               eisd.CompanyID,
               eisd.DIRECTID,
               eisd.EMPLOYID,
               eisd.INACTIVE,
               eisd.LEVEL,
               eng.EnglishName
           };

EDIT 2: I got exception:

Local sequence cannot be used in LINQ to SQL implementation of query operators except the Contains() operator.

as I try to execute the query and found the solution here IEnumerable.Except wont work, so what do I do?
and Need linq help

Answer 1

Use Linq to Dataset. From the MSDN : Creating a DataTable From a Query (LINQ to DataSet)

// Query the SalesOrderHeader table for orders placed 
// after August 8, 2001.
IEnumerable<DataRow> query =
    from order in orders.AsEnumerable()
    where order.Field<DateTime>("OrderDate") > new DateTime(2001, 8, 1)
    select order;

// Create a table from the query.
DataTable boundTable = query.CopyToDataTable<DataRow>();

If you have anonymous types :

From the Coder Blog : Using Linq anonymous types and CopyDataTable

It explains how to use MSDN's How to: Implement CopyToDataTable Where the Generic Type T Is Not a DataRow
