谁能给个用C#从SQL 2005中导出数据到excel文档的例子？非常感谢！

Question

C#最好做成个应用程序，有专门的窗口。

Answer 1

新建一个页面，在页面上输入你要生成的东西。在.cs页面中的PAGE_LOAD事件里加上这句话。：
Response.ContentType = "application/vnd.ms-excel"; 
        Response.AddHeader("Content-Disposition", "attachment;filename=" + System.Web.HttpUtility.UrlEncode("统计表", System.Text.Encoding.UTF8) + ".xls");

Answer 2

都是附带在项目里,,哪里有专门做个窗口的,,要时间地,,你能读2005的数据,,再搜下怎么新建EXCEL工作簿就行啦,基本写进去非常容易,只要找到那几个新建工作簿的命令就行了

winform?先将数据库导入DataSet，在DataGridView显示，然后再导入Excel就可以了private void insertToExcel(DataGridView gridView)
        {
            SaveFileDialog saveFileDialog = new SaveFileDialog();
            saveFileDialog.Filter = "Execl files (*.xls)|*.xls";
            saveFileDialog.FilterIndex = 0;
            saveFileDialog.RestoreDirectory = true;
            saveFileDialog.CreatePrompt = false; //文件不存在是是否提示新建
            saveFileDialog.OverwritePrompt = false; //文件存在是是否提示覆盖
            saveFileDialog.Title = "文件保存路径";
            saveFileDialog.ShowDialog();
            string strName = saveFileDialog.FileName;
            if (strName.Length != 0)
            {
                if (strName != FileName)
                {
                    System.Reflection.Missing miss = System.Reflection.Missing.Value;
                    Microsoft.Office.Interop.Excel.ApplicationClass excel = new Microsoft.Office.Interop.Excel.ApplicationClass();
                    excel.Application.Workbooks.Add(true); ;
                    excel.Visible = false;   //若是true，则在导出的时候会显示EXcel界面。
                    if (excel == null)
                    {
                        MessageBox.Show("EXCEL无法启动！", "错误", MessageBoxButtons.OK, MessageBoxIcon.Error);
                        return;
                    }
                    Microsoft.Office.Interop.Excel.Workbooks books = (Microsoft.Office.Interop.Excel.Workbooks)excel.Workbooks;
                    Microsoft.Office.Interop.Excel.Workbook book = (Microsoft.Office.Interop.Excel.Workbook)(books.Add(miss));
                    Microsoft.Office.Interop.Excel.Worksheet sheet = (Microsoft.Office.Interop.Excel.Worksheet)book.ActiveSheet;
                    sheet.Name = "Sheet1";                    for (int i = 0; i < gridView.ColumnCount; i++) //生成字段名称
                    {
                        excel.Cells[1, i + 1] = gridView.Columns[i].HeaderText.ToString();
                    }                    for (int i = 0; i < gridView.RowCount; i++) //填充数据

                            {
                                excel.Cells[i + 2, j + 1] = "" + gridView[i, j].Value.ToString();
                            }
                            else
                            {
                                excel.Cells[i + 2, j + 1] = gridView[j, i].Value.ToString();
                            }
                        }
                    }
                    sheet.SaveAs(strName, miss, miss, miss, miss, miss, Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlNoChange, miss, miss, miss);
                    book.Close(false, miss, miss);
                    books.Close();
                    excel.Quit();
                    System.Runtime.InteropServices.Marshal.ReleaseComObject(sheet);
                    System.Runtime.InteropServices.Marshal.ReleaseComObject(book);
                    System.Runtime.InteropServices.Marshal.ReleaseComObject(books);
                    System.Runtime.InteropServices.Marshal.ReleaseComObject(excel);
                    GC.Collect();
                    MessageBox.Show("数据已经成功导出到：" + saveFileDialog.FileName.ToString(), "追加完成", MessageBoxButtons.OK, MessageBoxIcon.Information);
                    KillExcel();
                }
                else
                { 
                    MessageBox.Show("该文件正在被使用，请用别的文件名", "提示", MessageBoxButtons.OK, MessageBoxIcon.Error);
                    this.dgvshow.DataSource = dt;
                }
