My favorite way to do this is with an extension function called 'Map':

public static void Map<T>(this IEnumerable<T> source, Action<T> func)
{
    foreach (T i in source)
        func(i);
}

Then you can add all the rows like so:

X.Map(item => this.dataGridView1.Rows.Add(item.ID, item.Name));

Let s assume you have a class like this   public class Staff       public int ID   get  set        public string Name   get  set        And assume you have dragged and dropped a DataGridView to your form  and name it dataGridView1   You need a BindingSource to hold your data to bind your DataGridView  This is how you can do it   private void frmDGV Load object sender  EventArgs e          dummy data     List lt Staff gt  lstStaff   new List lt Staff gt         lstStaff Add new Staff                 ID   1          Name    XX              lstStaff Add new Staff                 ID   2          Name    YY                 use binding source to hold dummy data     BindingSource binding   new BindingSource        binding DataSource   lstStaff         bind datagridview to binding source     dataGridView1 DataSource   binding

LINQ is a  query  language  thats the Q   so modifying data is outside its scope   That said  your DataGridView is presumably bound to an ItemsSource  perhaps of type ObservableCollection lt T gt  or similar  In that case  just do something like X ToList   ForEach yourGridSource Add   this might have to be adapted based on the type of source in your grid

first you need to add 2 columns to datagrid  you may do it at design time  see Columns property  then add rows as much as you need   this dataGridView1 Rows Add  1    XX
