c#操作wps中的excel

在c#中可以操作office的excel，這個是比較簡單，直接引入類庫操作。操作wps中的excel比其比較麻煩。
第一步：首先將wps的相關COM元件新增至引用. 工程->新增引用->COM->Kingsoft ET 2.0 Object Library / Upgrade Kinsoft ET 3.0 Object Library
第二步：Using KSO;Using ET;(匯入Kingsoft ET 2.0 Object Library時引用)
Using EXCEL;(匯入Upgrade Kinsoft ET 3.0 Object Library時引用)
第三步：將資料儲存在c#記憶體中定義的資料表中。
static void Dataprocessing(String tagid,String actionid) { System.Data.DataTable dt = new System.Data.DataTable(); //定義資料表變數 //資料庫中執行查詢的SQL語句 string sql = string.Format("SELECT * from RSSIData where ActionId='"+actionid+"'"); if (connection.State == ConnectionState.Closed) { connection.Open(); } SqlCommand cmd = new SqlCommand(sql, connection); SqlDataReader reader = cmd.ExecuteReader(); //生成表格的每列的標題（以我的程式為例） for (int i = 0; i < 7; i++) { if (i == 0){dt.Columns.Add("讀寫器ID", typeof(string)); } else if(i==1) { dt.Columns.Add("標籤ID", typeof(string)); } else if (i == 2) { dt.Columns.Add("標籤負載", typeof(string)); } else if (i == 3) { dt.Columns.Add("A通道RSSI值", typeof(string)); } else if (i == 4) { dt.Columns.Add("B通道RSSI值", typeof(string)); } else if (i == 5) { dt.Columns.Add("測試時間", typeof(string)); } else if (i == 6) { dt.Columns.Add("資料標識ID", typeof(string)); } } //根據資料庫查詢的結果，一一將資料填寫在對應的dt行中 while(reader.Read()) { DataRow dr = dt.NewRow(); for (int j = 0; j <7; j++)//for迴圈一次，生成一行資料 { if (j == 0){ dr[j] = reader["ReaderId"]; } else if(j==1){ dr[j] = reader["TagId"];} else if (j == 2) { dr[j] = reader["Payload"]; } else if (j == 3) { dr[j] = reader["RSSI"]; } else if (j == 4) { dr[j] = reader["RSSIB"]; } else if (j == 5) { dr[j] = reader["CollectTime"]; } else if (j == 6) { dr[j] = reader["ActionId"]; } } dt.Rows.Add(dr); } string s = OutputWPSExcel(dt, "第二組小方格測試的四個標籤資料報表", "C:\\users\\acer\\Desktop\\導師的\\定位資料統計\\"); Console.Write(s); }
第四步：將dt中的資料儲存在wps的excel中
/// /// 將DataTable的資料匯出顯示為報表(使用WPS) /// /// 要匯出的資料 /// 匯出報表的標題 /// 儲存檔案的路徑 /// static string OutputWPSExcel(System.Data.DataTable dt, string strTitle, string FilePath) { DateTime beforeTime = DateTime.Now; object missing = Type.Missing; Excel.Range objRange = null; string filename = ""; try { objApp = new Excel.Application(); objWorkBook = objApp.Workbooks.Add(Type.Missing); objWorkSheet = objWorkBook.ActiveSheet; int rowIndex = 4; int colIndex = 1; //取得列標題 foreach (DataColumn col in dt.Columns) { colIndex++; excel.Cells[4, colIndex] objWorkSheet.Cells[4,colIndex] = col.ColumnName; //設定標題格式為居中對齊 Range range = objWorkSheet.get_Range((object)objWorkSheet.Cells.get_Item(4, colIndex),(object) objWorkSheet.Cells.get_Item(4, colIndex)); range.Font.Bold = true; range.HorizontalAlignment = Excel.XlHAlign.xlHAlignCenter; range.Select(); } //取得表格中的資料 foreach (DataRow row in dt.Rows) { rowIndex++; colIndex = 1; foreach (DataColumn col in dt.Columns) { colIndex++; if (col.DataType == System.Type.GetType("System.DateTime")) { objWorkSheet.Cells[rowIndex, colIndex] = (Convert.ToDateTime(row[col.ColumnName].ToString())).ToString("yyyy-MM-dd"); objWorkSheet.get_Range((object)objWorkSheet.Cells.get_Item(rowIndex, colIndex));//設定日期型的欄位格式為居中對齊 } else if (col.DataType == System.Type.GetType("System.String")) { Range txtRange = (Range)objWorkSheet.Cells[rowIndex, colIndex]; txtRange.NumberFormatLocal = "@"; objWorkSheet.Cells[rowIndex, colIndex] = row[col.ColumnName].ToString(); objWorkSheet.get_Range((object)objWorkSheet.Cells.get_Item(rowIndex, colIndex),(object) objWorkSheet.Cells.get_Item(rowIndex, colIndex)).HorizontalAlignment = Excel.XlHAlign.xlHAlignCenter;//設定字元型的欄位格式為居中對齊 } else { objWorkSheet.Cells[rowIndex, colIndex] = row[col.ColumnName].ToString(); } } } //載入一個合計行 int rowSum = rowIndex + 1; int colSum = 2; objWorkSheet.Cells[rowSum, 2] = "合計"; objWorkSheet.get_Range((object)objWorkSheet.Cells.get_Item(rowSum, 2), (object)objWorkSheet.Cells.get_Item(rowSum, 2)).HorizontalAlignment = Excel.XlHAlign.xlHAlignCenter; //取得整個報表的標題 objWorkSheet.Cells[2, 2] = strTitle; //設定整個報表的標題格式 objWorkSheet.get_Range((object)objWorkSheet.Cells.get_Item(2, 2), (object)objWorkSheet.Cells.get_Item(2, 2)).Font.Bold = true; objWorkSheet.get_Range((object)objWorkSheet.Cells.get_Item(2, 2), (object)objWorkSheet.Cells.get_Item(2, 2)).Font.Size = 22; //設定報表表格為最適應寬度 objWorkSheet.get_Range((object)objWorkSheet.Cells.get_Item(4, 2), (object)objWorkSheet.Cells.get_Item(rowSum, colIndex)).Select(); objWorkSheet.get_Range((object)objWorkSheet.Cells.get_Item(4, 2), (object)objWorkSheet.Cells.get_Item(rowSum, colIndex)).Columns.AutoFit(); //設定整個報表的標題為跨列居中 objWorkSheet.get_Range((object)objWorkSheet.Cells.get_Item(2, 2), (object)objWorkSheet.Cells.get_Item(2, colIndex)).Select(); objWorkSheet.get_Range((object)objWorkSheet.Cells.get_Item(2, 2), (object)objWorkSheet.Cells.get_Item(2, colIndex)).HorizontalAlignment = Excel.XlHAlign.xlHAlignCenterAcrossSelection; DateTime afterTime = DateTime.Now; filename =FilePath+ strTitle + "_" + DateTime.Now.ToString("yyyyMMddHHmmssff") + ".xls"; //儲存檔案 objWorkBook.SaveAs(filename, missing, missing, missing, missing, missing, Excel.XlSaveAsAccessMode.xlNoChange, missing, missing, missing, missing); objWorkBook.Close(missing, missing, missing); } finally { ReleaseComObject(objRange); ReleaseComObject(objWorkSheet); ReleaseComObject(objWorkBook); } return filename; } static void ReleaseComObject(object obj) { if (obj != null) { System.Runtime.InteropServices.Marshal.ReleaseComObject(obj); obj = null; } }
