1、DataGridView

DataGridView赋值后 通过RowPostPaint事件绘制行号

         private void AddXh()
         {
             DataGridViewTextBoxColumn col = new DataGridViewTextBoxColumn();
             col.Name = "xh";
             col.HeaderText = "序号";
             col.FillWeight = ;
             dgvEquipment.Columns.Insert(, col);

             dgvEquipment.RowPostPaint += dgvEquipment_RowPostPaint;
         }

         private void dgvEquipment_RowPostPaint(object sender, DataGridViewRowPostPaintEventArgs e)
         {
             foreach (DataGridViewRow row in dgvEquipment.Rows)
             {
                 row.Cells["xh"].Value = row.Index + ;
             }
         }
