How to add column to datagridview using AddRange c#

i saw people use this below code to add many column at a time. here is code

var col3 =newDataGridViewTextBoxColumn();var col4 =newDataGridViewCheckBoxColumn();

        col3.HeaderText="Column3";
        col3.Name="Column3";

        col4.HeaderText="Column4";
        col4.Name="Column4";

        dataGridView1.Columns.AddRange(newDataGridViewColumn[]{col3,col4});

but my situation is bit different. this way i am adding column to datagridview in loop.

foreach(DataColumn column in retriever.Columns){
    dataGridView1.Columns.Add(column.ColumnName, column.ColumnName);}

anyone can tell me how to modify my above code to use addrange() instead of add() function. my intention is to add all columns at a time instead of adding loop.
