那位老兄能给我一些代码让我对DataGridView表中的数据快速进行添加、修改、删除，我想你们应该做过这方面的小型软件……

dataGridView1.Rows.Add();对行进行添加；
dataGridView1.AllowUserToAddRows = false;不显示新添加行；
dataGridView1.currentcell.value=xx;对当前单元格值的设置；
private void doDeleteEntireColumnCMD(DataGridView datagv)；对单元格所在的列进行删除；
        {
            try
            {
                datagv.SelectionMode = DataGridViewSelectionMode.FullColumnSelect;
                datagv.CurrentCell.Selected = true;
                if (datagv.Columns.Count > 0)
                {

                    if (MessageBox.Show("Are you sure to delete the Entire Column?!", "Tips", MessageBoxButtons.OKCancel, MessageBoxIcon.Asterisk) == DialogResult.OK)
                    {

                        string columnname = datagv.Columns[datagv.CurrentCell.ColumnIndex].Name.ToString();
                        datagv.Columns.Remove(columnname);
                    }

                }
                else
                {
                    deleteEntireColumnToolStripMenuItem.Enabled = false;
                }
                datagv.SelectionMode = DataGridViewSelectionMode.CellSelect;
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message, "Tips", MessageBoxButtons.OK, MessageBoxIcon.Information);
            }
        }
