1.添加引用：  
  
Aspose.Cells.dll（咱們就叫工具包吧，能夠從網上下載。關於它的操做我在「Aspose.Cells操做說明 中文版 下載 Aspose C# 導出Excel 實例」一文中的說。這裏你暫時也可不理會它。）  
即便沒有安裝office也能用噢，這是一個好強的大工具。  
2.編寫Excel操做類  
  
using System;  
using System.Collections.Generic;  
using System.Text;  
using Aspose.Cells;  
using System.Data;  
public class AsposeExcel  
{  
    private string outFileName = "";  
    private string fullFilename = "";  
    private Workbook book = null;  
    private Worksheet sheet = null;  
    public AsposeExcel(string outfilename, string tempfilename) //導出構造數  
    {  
        outFileName = outfilename;  
        book = new Workbook();  
        // book.Open(tempfilename);這裏咱們暫時不用模板  
        sheet = book.Worksheets[0];  
    }  
    public AsposeExcel(string fullfilename) //導入構造數  
    {  
        fullFilename = fullfilename;  
        // book = new Workbook();  
        // book.Open(tempfilename);  
        // sheet = book.Worksheets[0];  
    }  
    private void AddTitle(string title, int columnCount)  
    {  
        sheet.Cells.Merge(0, 0, 1, columnCount);  
        sheet.Cells.Merge(1, 0, 1, columnCount);  
        Cell cell1 = sheet.Cells[0, 0];  
        cell1.PutValue(title);  
        cell1.Style.HorizontalAlignment = TextAlignmentType.Center;  
        cell1.Style.Font.Name = "黑體";  
        cell1.Style.Font.Size = 14;  
        cell1.Style.Font.IsBold = true;  
        Cell cell2 = sheet.Cells[1, 0];  
        cell1.PutValue("查詢時間：" + DateTime.Now.ToLocalTime());  
        cell2.SetStyle(cell1.Style);  
    }  
    private void AddHeader(DataTable dt)  
    {  
        Cell cell = null;  
        for (int col = 0; col < dt.Columns.Count; col++)  
        {  
            cell = sheet.Cells[0, col];  
            cell.PutValue(dt.Columns[col].ColumnName);  
            cell.Style.Font.IsBold = true;  
        }  
    }  
    private void AddBody(DataTable dt)  
    {  
        for (int r = 0; r < dt.Rows.Count; r++)  
        {  
            for (int c = 0; c < dt.Columns.Count; c++)  
            {  
                sheet.Cells[r + 1, c].PutValue(dt.Rows[R]­[c].ToString());  
            }  
        }  
    }  
    //導出------------下一篇會用到這個方法  
    public Boolean DatatableToExcel(DataTable dt)  
    {  
        Boolean yn = false;  
        try  
        {  
            //sheet.Name = sheetName;  
            //AddTitle(title, dt.Columns.Count);  
            //AddHeader(dt);  
            AddBody(dt);  
            sheet.AutoFitColumns();  
            //sheet.AutoFitRows();  
            book.Save(outFileName);  
            yn = true;  
            return yn;  
        }  
        catch (Exception e)  
        {  
            return yn;  
            // throw e;  
        }  
    }  
    public DataTable ExcelToDatatalbe()//導入  
    {  
        Workbook book = new Workbook();  
        book.Open(fullFilename);  
        Worksheet sheet = book.Worksheets[0];  
        Cells cells = sheet.Cells;  
        //獲取excel中的數據保存到一個datatable中  
        DataTable dt_Import = cells.ExportDataTableAsString(0, 0, cells.MaxDataRow + 1, cells.MaxDataColumn + 1, false);  
        // dt_Import.  
        return dt_Import;  
    }  
}[/R]  
  
3. Word導出  
//設置文件類型  
// saveFileDialog爲一個對話框控件  
//若是沒有人工具欄中拉，  
//能夠：SaveFileDialog saveFileDialog1=new SaveFileDialog();  
saveFileDialog1.Filter = "導出Excel (*.xls)|*.xls|Word (*.doc)|*.doc";  
saveFileDialog1.FilterIndex = 1;  
saveFileDialog1.RestoreDirectory = true;  
saveFileDialog1.CreatePrompt = true;  
saveFileDialog1.Title = "導出文件保存路徑";  
//saveFileDialog1.ShowDialog();  
//string strName = saveFileDialog1.FileName;  
//設置默認文件類型顯示順序  
//saveFileDialog1.FilterIndex = 2;  
//保存對話框是否記憶上次打開的目錄  
saveFileDialog1.RestoreDirectory = true;  
//點了保存按鈕進入  
if (saveFileDialog1.ShowDialog() == DialogResult.OK)  
{  
    //得到文件路徑  
    string localFilePath = saveFileDialog1.FileName.ToString();  
    //獲取文件名，不帶路徑  
    string fileNameExt = localFilePath.Substring(localFilePath.LastIndexOf("\\") + 1);  
    //獲取文件路徑，不帶文件名  
    string FilePath = localFilePath.Substring(0, localFilePath.LastIndexOf("\\"));  
    //給文件名前加上時間  
    string newFileName = DateTime.Now.ToString("yyyyMMdd") + fileNameExt;  
    //在文件名里加字符  
    //saveFileDialog1.FileName.Insert(1,"dameng");  
    saveFileDialog1.FileName = FilePath + "\\" + newFileName;  
    System.IO.FileStream fs = (System.IO.FileStream)saveFileDialog1.OpenFile();//輸出文件  
    StreamWriter writer = new StreamWriter(fs);  
    writer.Write("tttt");//這裏就是你要導出到word的內容，內容是你什麼你自已DIY  
    writer.Flush();  
    writer.Close();  
    fs.Close();  
}  
  
4. 導出datatable到excel  
  
DataTable dt = null;  
if (ds_all.Tables[0] != null)  
{  
    dt = ds_all.Tables[0];  
}  
else {  
    MessageBox.Show("沒有數據記錄", "*^_^* 舒適提示信息", MessageBoxButtons.OK);  
    return;  
}  
//上面只是取datatable，你本身diy  
AsposeExcel tt = new AsposeExcel(saveFileDialog1.FileName, "");//不用模板, saveFileDialog1是什麼？上面已經說過  
bool OK_NO = tt.DatatableToExcel(dt);  
if (OK_NO)  
{  
    MessageBox.Show("導出成功", "*^_^* 舒適提示信息", MessageBoxButtons.OK);  
}  
else  
{  
}  
  
5. Excel導入  
private void 導入ToolStripMenuItem_Click(object sender, EventArgs e)  
{  
    string localFilePath = "";  
    //點了保存按鈕進入  
    if (openFileDialog1.ShowDialog() == DialogResult.OK)// openFileDialog1不要再問我這是什麼！  
    {  
        //得到文件路徑  
        localFilePath = openFileDialog1.FileName.ToString();  
}  
    AsposeExcel tt = new AsposeExcel(localFilePath);  
    DataTable dt;  
    try  
    {  
        dt = tt.ExcelToDatatalbe();  
    }  
    catch (Exception ex)  
    {  
        return;  
    }  
//有了datatable你本身就能夠DIY啦,下面是我本身的你不用理  
if (ddlResidence.SelectedValue == "違章確認")  
    {  
        if (dt.Rows[0][9].ToString() != "違章確認")  
        {  
                            return;  
        }  
        row = dt.Rows.Count;  
        if (row <= 0) return;  
        for (int i = 0; i < dt.Rows.Count; i++)  
        {  
            bllviola.Up_Confirmed_ByVnum(dt.Rows[i][6].ToString(), dt.Rows[i][9].ToString());  
        }  
        this.GridView1.DataSource = dt;  
        GridView1.DataBind();  
}
