binding string to a datagrid

Hi, I have a problem to bind a string in my datagrid. I have search, some code on the net which allow to fill a datagrid with a simple string, but I didn't find any. Some codes gave methode like datagrid1.databind(); but there is no method like that , there is just DataBindings() which is more usable for data from tables. After i tried to create collection and array with my string, there is no error but the single thing it writes is the lenght of my string, but it'sn't what I want. i just like to see my string in the datagrid. There is my code: StreamReader srRead = new StreamReader("c:/exemple.txt"); String name=""; srRead = File.OpenText("c:/exemple.txt"); /*string with my data to fill in the datagrid*/ name =srRead.ReadLine(); ArrayList arr = new ArrayList(15); arr.Add(name); MessageBox.Show(arr[0].ToString());//String that i want to insert into datagrid dataGrid1.DataSource= arr; /* return on the datagrid the number of char in the string with Length for the column name*/ //dataGrid1.DataSource= arr[0];// return error /*DataBinding complexe accepte IList ou IListSource comme source de données*/ dataGrid1.Refresh(); /*I tried to with a stringCollection but it doesn't run*/ StringCollection gg= new StringCollection(); gg.Add(name); gg.Insert(0,name); I hope that you can understand my problem... and I hope too that you have the solution, since 2 days I'm on this problem (maybe because I 'm novice) , and now I don't know what to do. Thank you to take time for me bye clem
