C# winform 导出导入Excel/Doc 完整实例教程 使用Aspose.Cells.dll——第一篇

还真没做过winform的导出导入，今天上网百度了一下。结果---

所以还是我自己写个吧。之前做过web的，半搬半做就OK。

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;
    }
}

3导出按钮事件中编写导出数据方法：

private void bt_excel_out_Click(object sender, EventArgs e)
        {
           
            SaveFileDialog saveFileDialog1 = new SaveFileDialog();//如果你直接从对话框中拉出来，就不用new了噢。

          //设置文件类型
            saveFileDialog1.Filter = "导出Excel (*.xls)|*.xls|Word (*.doc)|*.doc";
            saveFileDialog1.FilterIndex = 2;
            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;

                saveFileDialog1.FileName = FilePath + "//" + newFileName;
                System.IO.FileStream fs = (System.IO.FileStream)saveFileDialog1.OpenFile();//输出文件  

                //下面是导出数据到doc       导出到excel请看下一篇（发现没有AsposeExcel
类还没有用到呢，那正是导出到excel要用的）
                StreamWriter writer = new StreamWriter(fs);
                writer.Write("tttt");//这里就是你要导出到word文档的数据
                writer.Flush();
                writer.Close();
                fs.Close();

            }

        }

 

迟的我会上传一份全面的 C# winform教程，若有需要留意下噢。
