c# datagridview 相关操作。

string[] newRow = {"long","d","b"};
Gridview.Rows.Insert(Gridview.Rows.Count, newRow);

datagridview 设置某行某列的单元格可修改：

    private void SetGridCellEdit()
        {
            if (repgrid != null && repgrid.Rows.Count > )
            {
                string dyeno = string.Empty;
                for (int i = ; i < repgrid.Rows.Count; i++)
                {
                    if (repgrid.Rows[i].Cells["Coldyeno"].Value != null)
                    {
                        dyeno = repgrid.Rows[i].Cells["Coldyeno"].Value.ToString();
                        if (dyeno.Equals("X022")
                            || dyeno.Equals("X009")
                            || dyeno.Equals("X008")
                            || dyeno.Equals("X001")
                            ) //
                        {
                            DataGridViewCell viewCell = repgrid.Rows[i].Cells["Coltarget"];
                            repgrid.CurrentCell = viewCell;
                            viewCell.ReadOnly = false;
                            repgrid.BeginEdit(true);
                        }
                        else
                        {
                            DataGridViewCell viewCell = repgrid.Rows[i].Cells["Coltarget"];
                            repgrid.CurrentCell = viewCell;
                            viewCell.ReadOnly = true;
                        }
                    }
                }
