How can I convert values. Row to string and insert into a combobox? C#

Question

I have the following code:

for(int i = 1; i<dataTable.Rows.Count; i++)
{comboBox.Items.Add( dataTable.Rows[i].ToString());}

When I run the application, in combobox just appears to me System.Data.DataRow. I wish I could see all the items on the combobox.
