string goodsName = this.GridView1.DataKeys[e.RowIndex][0].ToString();
string salePrice = ((TextBox)this.GridView1.Rows[e.RowIndex].Cells[1].Controls[0]).Text.ToString();
string discount = ((TextBox)this.GridView1.Rows[e.RowIndex].Cells[2].Controls[0]).Text.ToString();
salePrice discount对应的数据库 类型是numeric ,但我在这里不知道应该怎么把string去把它转换为数据库所需要的numeric
