C# WinForm 导出导入Excel/Doc 完整实例教程[使用Aspose.Cells.dll]

[csharp] view plain copy
1.添加引用：  
  
Aspose.Cells.dll（我们就叫工具包吧，可以从网上下载。关于它的操作我在“Aspose.Cells操作说明 中文版 下载 Aspose C# 导出Excel 实例”一文中的说。这里你暂时也可不理会它。）  
即使没有安装office也能用噢，这是一个好强的大工具。  
2.编写Excel操作类  
  
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) //导出构造数  
    {  
        outFileName = outfilename;  
        book = new Workbook();  
        // book.Open(tempfilename);这里我们暂时不用模板  
        sheet = book.Worksheets[0];  
    }  
    public AsposeExcel(string fullfilename) //导入构造数  
    {  
        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 = "黑体";  
        cell1.Style.Font.Size = 14;  
        cell1.Style.Font.IsBold = true;  
        Cell cell2 = sheet.Cells[1, 0];  
        cell1.PutValue("查询时间：" + 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());  
            }  
        }  
    }  
    //导出------------下一篇会用到这个方法  
    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()//导入  
    {  
        Workbook book = new Workbook();  
        book.Open(fullFilename);  
        Worksheet sheet = book.Worksheets[0];  
        Cells cells = sheet.Cells;  
        //获取excel中的数据保存到一个datatable中  
        DataTable dt_Import = cells.ExportDataTableAsString(0, 0, cells.MaxDataRow + 1, cells.MaxDataColumn + 1, false);  
        // dt_Import.  
        return dt_Import;  
    }  
}[/R]  
  
3. Word导出  
//设置文件类型  
// saveFileDialog为一个对话框控件  
//如果没有人工具栏中拉，  
//可以：SaveFileDialog saveFileDialog1=new SaveFileDialog();  
saveFileDialog1.Filter = "导出Excel (*.xls)|*.xls|Word (*.doc)|*.doc";  
saveFileDialog1.FilterIndex = 1;  
saveFileDialog1.RestoreDirectory = true;  
saveFileDialog1.CreatePrompt = true;  
saveFileDialog1.Title = "导出文件保存路径";  
//saveFileDialog1.ShowDialog();  
//string strName = saveFileDialog1.FileName;  
//设置默认文件类型显示顺序  
//saveFileDialog1.FilterIndex = 2;  
//保存对话框是否记忆上次打开的目录  
saveFileDialog1.RestoreDirectory = true;  
//点了保存按钮进入  
if (saveFileDialog1.ShowDialog() == DialogResult.OK)  
{  
    //获得文件路径  
    string localFilePath = saveFileDialog1.FileName.ToString();  
    //获取文件名，不带路径  
    string fileNameExt = localFilePath.Substring(localFilePath.LastIndexOf("\") + 1);  
    //获取文件路径，不带文件名  
    string FilePath = localFilePath.Substring(0, localFilePath.LastIndexOf("\"));  
    //给文件名前加上时间  
    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();//输出文件  
    StreamWriter writer = new StreamWriter(fs);  
    writer.Write("tttt");//这里就是你要导出到word的内容，内容是你什么你自已DIY  
    writer.Flush();  
    writer.Close();  
    fs.Close();  
}  
  
4. 导出datatable到excel  
  
DataTable dt = null;  
if (ds_all.Tables[0] != null)  
{  
    dt = ds_all.Tables[0];  
}  
else {  
    MessageBox.Show("没有数据记录", "*^_^* 温馨提示信息", 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？上面已经说过  
bool OK_NO = tt.DatatableToExcel(dt);  
if (OK_NO)  
{  
    MessageBox.Show("导出成功", "*^_^* 温馨提示信息", MessageBoxButtons.OK);  
}  
else  
{  
}  
  
5. Excel导入  
private void 导入ToolStripMenuItem_Click(object sender, EventArgs e)  
{  
    string localFilePath = "";  
    //点了保存按钮进入  
    if (openFileDialog1.ShowDialog() == DialogResult.OK)// openFileDialog1不要再问我这是什么！  
    {  
        //获得文件路径  
        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 == "违章确认")  
    {  
        if (dt.Rows[0][9].ToString() != "违章确认")  
        {  
                            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();  
}
