方法
1、获取仓库ID数组方法
//获取仓库ID数组方法 public int[] StockIDArray(string stockSQL) { #region 获取Stockid数组 //执行存储过程,取到有数据的仓库id SqlCommand commStock = new SqlCommand(stockSQL, conn); //定义执行SQL语句的对象,并将SQL语句赋予对象 SqlDataAdapter Stockid = new SqlDataAdapter(commStock); //执行连接 DataSet dsStock = new DataSet(); Stockid.Fill(dsStock); DataTable dtStock = new DataTable(); dtStock = dsStock.Tables[0]; //将stockid传进list赋值给数组 List<int> liststock = new List(); for (int i = 0; i < dtStock.Rows.Count; i++) { liststock.Add(int.Parse(dtStock.Rows[i]["FSTOCKID"].ToString())); } List<int> listNew = new List(); //删除重复仓位id foreach (int eachString in liststock) { if (!listNew.Contains(eachString)) listNew.Add(eachString); } int[] stockID = listNew.ToArray(); #endregion return stockID; }
2、补全仓库12个月数据
//补全仓库12个月数据 public DataTable CompleteYearData(DataTable dt, int[] stockidArray) { /*传入参数 dt //stockid本年度数据表 stockidArray //stockid集合,如果为空配置空数据 */ #region 补全12个月数据并排序 for (int m = 1; m <= 12; m++) { //月份需补全0才能正确排序 String monthname; if (m < 10) { monthname = "0" + m.ToString() + "月"; } else { monthname = m.ToString() + "月"; } //判断是否存在当月数据,不存在插入一行当月数据 DataRow[] dataRows = dt.Select("月份" + "='" + monthname + "'"); if (dataRows.Length > 0) { continue; } if (dataRows.Length <= 0 && stockidArray.Length <= 0) { DataRow newRow = dt.NewRow(); newRow["月份"] = monthname; newRow["不常用品种数"] = 0; dt.Rows.Add(newRow); } else { DataRow newRow = dt.NewRow(); newRow["组织名称"] = dt.Rows[0][0]; newRow["仓库名称"] = dt.Rows[0][1]; newRow["FSTOCKID"] = dt.Rows[0][2]; newRow["月份"] = monthname; newRow["不常用品种数"] = 0; dt.Rows.Add(newRow); } } dt.DefaultView.Sort = "月份 ASC";//按月份倒序 dt = dt.DefaultView.ToTable();//返回一个新的DataTable #endregion return dt; }
