convert linq query results to datatable C#

Question

I want to convert the linq query results to datatable so that I can assign datatable to GridView to show it on asp page.

However I am not able to convert the results

Answer 1

First declare a new DataTable and add columns, in this :

DataTable dt = new DataTable();
dt.Columns.Add("FirstName");
dt.Columns.Add("LastName");
DataRow row = null;

Now I simply iterate through the query and fill a DataTable:

foreach (var rowObj in query)
{
    row = dt.NewRow();
    dt.Rows.Add(rowObj.FirstName, rowObj.LastName);
}
