本人寫的代碼。

可供參考：using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using System.Data; using System.Data.SqlClient; using Microsoft.Office.Interop.Excel; using System.IO; using System.Configuration; using System.Drawing; namespace excel { public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { string constring = ConfigurationManager.ConnectionStrings["CS"].ToString(); SqlConnection con = new SqlConnection(constring); con.Open(); SqlDataAdapter da = new SqlDataAdapter("select * from counter", con); DataSet a = new DataSet(); da.Fill(a); //建立一個文件 夾 //Console.WriteLine("...正在創建文件夾wtq.../n/n/n"); DirectoryInfo dir = new DirectoryInfo("c://wtq//wtq"); if (!dir.Exists) { dir.Create(); } else { Response.Write("你創建的文件夾已存在，/n/n/n"); } //開始EXCEL object objOpt = System.Reflection.Missing.Value; Microsoft.Office.Interop.Excel.Application ap = new Application(); ap.Visible = true; Microsoft.Office.Interop.Excel._Workbook wk = ap.Workbooks.Add(objOpt); Sheets sheet = wk.Sheets; // Microsoft.Office.Interop.Excel._Worksheet ws = (Microsoft.Office.Interop.Excel._Worksheet)wk.ActiveSheet; _Worksheet ws = (_Worksheet)sheet.get_Item(2); _Worksheet wss = (_Worksheet)sheet.get_Item(1); ws.Activate();//激活那個sheet ws.Name = "重命名錶單";//重命名錶單 ws.Columns.ColumnWidth = 20;//設置列寬 ws.Columns.RowHeight = 20;//設置行號 //ap.Cells[1, 1] = "id"; //ap.Cells[1, 2] = "businessNum"; //ap.Cells[1, 3] = "exportTime"; //ap.Cells[1, 4] = "shipSide"; //ap.Cells[1, 5] = "shipOwner"; //ap.Cells[1, 6] = "destinationPort"; ws.Cells[1, 1] = "id"; ws.Cells[1, 2] = "businessNum"; ws.Cells[1, 3] = "exportTime"; ws.Cells[1, 4] = "shipSide"; ws.Cells[1, 5] = "shipOwner"; ws.Cells[1, 6] = "destinationPort"; wss.Cells[1, 1] = "標識符"; wss.Cells[1, 2] = "業務號"; wss.Cells[1, 3] = "ETD"; wss.Cells[1, 4] = "碼頭"; wss.Cells[1, 5] = "船長"; wss.Cells[1, 6] = "目的港"; for (int i = 0; i < a.Tables[0].Rows.Count; i++) { //ap.Cells[i + 2, 1] = a.Tables[0].Rows[i][0]; //ap.Cells[i + 2, 2] = a.Tables[0].Rows[i][1]; //ap.Cells[i + 2, 3] = a.Tables[0].Rows[i][2]; //ap.Cells[i + 2, 4] = a.Tables[0].Rows[i][3]; //ap.Cells[i + 2, 5] = a.Tables[0].Rows[i][4]; //ap.Cells[i + 2, 6] = a.Tables[0].Rows[i][5]; ws.Cells[i + 2, 1] = a.Tables[0].Rows[i][0]; ws.Cells[i + 2, 2] = a.Tables[0].Rows[i][1]; ws.Cells[i + 2, 3] = a.Tables[0].Rows[i][2]; ws.Cells[i + 2, 4] = a.Tables[0].Rows[i][3]; ws.Cells[i + 2, 5] = a.Tables[0].Rows[i][4]; ws.Cells[i + 2, 6] = a.Tables[0].Rows[i][5]; wss.Cells[i + 2, 1] = a.Tables[0].Rows[i][0]; wss.Cells[i + 2, 2] = a.Tables[0].Rows[i][1]; wss.Cells[i + 2, 3] = a.Tables[0].Rows[i][2]; wss.Cells[i + 2, 4] = a.Tables[0].Rows[i][3]; wss.Cells[i + 2, 5] = a.Tables[0].Rows[i][4]; wss.Cells[i + 2, 6] = a.Tables[0].Rows[i][5]; } Range range = ws.get_Range(ws.Cells[1,1],ws.Cells[1,6]); //選定單元格的範圍 range.Borders.Color = System.Drawing.ColorTranslator.ToOle(Color.Red);//設置邊框的顏色 // range.Borders.get_Item(XlBordersIndex.xlEdgeBottom).Color = ColorTranslator.ToOle(Color.Blue); range.Font.Color =ColorTranslator.ToOle(Color.Blue);//設置區域字體顏色 range.Font.Bold = true;//設置字體爲粗體。 range.Columns.RowHeight = 40;//設置局部行高 range.Columns.ColumnWidth = 40;//設置局部列寬 range.Interior.Color = 15; //設置背景顏色 range.BorderAround(XlLineStyle.xlDot, XlBorderWeight.xlThick, XlColorIndex.xlColorIndexAutomatic, 15); try { wk.SaveAs("c://wtq//wtq//sjj", objOpt, null, null, false, false, XlSaveAsAccessMode.xlNoChange, null, null, null, null, null); } catch (Exception ex) { } // wk.Close(false,objOpt,objOpt); } } } 

 

注意：使用   wss.Cells[i + 2, 6] = a.Tables[0].Rows[i][5];這種方法給excel表格效率非常低。

應當使用如下，

這是我定義好的藉口以後可以使用。

 

using System; using System.Collections.Generic; using System.Linq; using System.Web; using Microsoft.Office.Interop.Excel; using System.Reflection; using System.Data; using System.IO; using System.Text; namespace excel { public class exportExcel { public exportExcel() { } private Application excelApp = null;//定義excel應用程序 private _Workbook workBook = null;//定義工作簿 private _Worksheet workSheet =null; //定義工作表 private Range range = null; //定義單元格區域 private object objOpt = Missing.Value; public void Create() // { /*初始化對象*/ excelApp = new Application(); workBook = excelApp.Workbooks.Add(objOpt); workSheet = (_Worksheet)workBook.ActiveSheet; excelApp.Visible = true; } /// <summary> /// 從dataset中獲取數據，並將其存入到excel中。 /// </summary> /// <param name="ds">數據集</param> /// <param name="title">標題數組</param> public void GetDataToExcel(DataSet ds, object[] title) { int rowCount = ds.Tables[0].Rows.Count;//數據集的行數。 // int colCount = ds.Tables[0].Columns.Count;//數據集的列數。 int colCount = 6; object[,] data=new object[rowCount,colCount]; for (int i = 0;i < colCount; i++) //設置標題 { workSheet.Cells[1 , i+1] = title[i] ; } for (int i = 0; i < rowCount; i++) { for (int j = 0; j < colCount; j++) { data[i, j] = ds.Tables[0].Rows[i][j].ToString(); } } workSheet.get_Range(workSheet.Cells[2,1],workSheet.Cells[rowCount+1,colCount]).Value2=data; range = workSheet.get_Range(workSheet.Cells[1, 1], workSheet.Cells[1, colCount]); //選定單元格的範圍 range.Interior.Color = 255; //設置背景顏色 range.BorderAround(XlLineStyle.xlDot, XlBorderWeight.xlThick, XlColorIndex.xlColorIndexAutomatic, 15); //定義一個目錄 DirectoryInfo dir = new DirectoryInfo("c://wtq//wtq"); if (!dir.Exists) { dir.Create(); } else { HttpContext.Current.Response.Write("你創建的文件夾已存在，/n/n/n"); } try { workBook.SaveAs("c://wtq//wtq//sjj", objOpt, null, null, false, false, XlSaveAsAccessMode.xlNoChange, null, null, null, null, null); } catch (Exception ex) { HttpContext.Current.Response.Write(ex); } } } } 

使用旁邊代碼：workSheet.get_Range(workSheet.Cells[2,1],workSheet.Cells[rowCount+1,colCount]).Value2=data;

這種效率比較高。
