還真沒做過Aspose.Cells在winform的導(dǎo)出導(dǎo)入，今天上網(wǎng)百度了一下。結(jié)果……所以還是我自己寫個吧。之前做過web的，半搬半做就OK。

1、添加引用：Aspose.Cells.dll（我們就叫工具包吧，可以從網(wǎng)上下載。關(guān)于它的操作我在“Aspose.Cells操作說明 中文版 下載 Aspose C# 導(dǎo)出Excel 實例”一文中的說。這里你暫時也可不理會它。）

即使沒有安裝office也能用噢，這是一個好強的大工具。

2、編寫Excel操作類

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(dǎo)出構(gòu)造數(shù)
    {
        outFileName = outfilename;
        book = new Workbook();
        // book.Open(tempfilename);這里我們暫時不用模板
        sheet = book.Worksheets[0];
    }
    public AsposeExcel(string fullfilename)//導(dǎo)入構(gòu)造數(shù)
    {
        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(dǎo)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(dǎo)入
    {
        Workbook book = new Workbook();
        book.Open(fullFilename);
        Worksheet sheet = book.Worksheets[0];
        Cells cells = sheet.Cells;
        //獲取excel中的數(shù)據(jù)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;
    }
}

3. Word導(dǎo)出

//設(shè)置文件類型
// saveFileDialog為一個對話框控件
//如果沒有人工具欄中拉，
//可以：SaveFileDialog saveFileDialog1=new SaveFileDialog();
saveFileDialog1.Filter = "導(dǎo)出Excel (*.xls)|*.xls|Word (*.doc)|*.doc";
saveFileDialog1.FilterIndex = 1;
saveFileDialog1.RestoreDirectory = true;
saveFileDialog1.CreatePrompt = true;
saveFileDialog1.Title = "導(dǎo)出文件保存路徑";
//saveFileDialog1.ShowDialog();
//string strName = saveFileDialog1.FileName;
//設(shè)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)
{
//獲得文件路徑
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");//這里就是你要導(dǎo)出到word的內(nèi)容，內(nèi)容是你什么你自已DIY
writer.Flush();
writer.Close();
fs.Close();
}

4. 導(dǎo)出datatable到excel

DataTable dt = null;
if (ds_all.Tables[0] != null)
{
dt = ds_all.Tables[0];
}
else {
MessageBox.Show("沒有數(shù)據(jù)記錄", "*^_^* 溫馨提示信息", MessageBoxButtons.OK);
return;
}
//上面只是取datatable，你自己diy
AsposeExcel tt = new AsposeExcel(saveFileDialog1.FileName, "");//不用模板, saveFileDialog1是什么？上面已經(jīng)說過
bool OK_NO = tt.DatatableToExcel(dt);
if (OK_NO)
{
MessageBox.Show("導(dǎo)出成功", "*^_^* 溫馨提示信息", MessageBoxButtons.OK);
}
else
{
}

5. Excel導(dǎo)入

private void 導(dǎo)入ToolStripMenuItem_Click(object sender, EventArgs e)
{
string localFilePath = "";
//點了保存按鈕進入
if (openFileDialog1.ShowDialog() == DialogResult.OK)// openFileDialog1不要再問我這是什么！
{
//獲得文件路徑
localFilePath = openFileDialog1.FileName.ToString();
}
AsposeExcel tt = new AsposeExcel(localFilePath);
DataTable dt;
try
{
dt = tt.ExcelToDatatalbe();
}
catch (Exception ex)
{
return;
}
//有了datatable你自己就可以DIY啦,下面是我自己的你不用理
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();
}
