用datagridview绑定数组后无法编辑，这是为什么

自己写一个小例子，datagridview直接绑定datatable，可以实现增删改；直接绑定类stringArray数组，则在Form中无法编辑（即点击单元格不能进入编辑状态），也无法增删，请问这是为什么，代码如下：



public partial class Form1 : Form

    {

        private DataTable routerDataTable;

        private BindingSource bs = new BindingSource();

        // DataGridView绑定显示的是第一公共属性，所以结构体不能作为绑定对象，只有类才有属性

        private class stringArray

        {

            private string s;



            public string S

            {

                get { return s; }

            }



            public stringArray(string sa)

            {

                s = sa;

            }

        }



        private stringArray[] sa = new stringArray[] { new stringArray("a"), new stringArray("b") };



        

        

        public Form1()

        {

            InitializeComponent();

            

        }



        private void Form1_Load(object sender, EventArgs e)

        {

                       

        }



        private void buttonBind_Click(object sender, EventArgs e)

        {

            routerDataTable = DbHelperOleDb.QueryDataTable("select * from router");

            dataGridView1.DataSource = routerDataTable;

            

        }



       



        // 删除一行的话必须先选中那一行，然后再按delete键

        private void saveButton_Click(object sender, EventArgs e)

        {

            using (OleDbConnection connection = new OleDbConnection(DbHelperOleDb.connectionString))

            {

                OleDbDataAdapter da = new OleDbDataAdapter("select * from router", connection);

                OleDbCommandBuilder cb = new OleDbCommandBuilder(da);

                da.Update(routerDataTable);

            }

        }



        private void buttonBindArray_Click(object sender, EventArgs e)

        {

            

            

            bs.DataSource = sa;

     

            dataGridView1.DataSource = bs;

        }







        

    }
