将Textbox、listview控件里的数据导入Excel

注:先要添加microsoft.Office.Interop.Excel 11.0版本引用,若没有此引用,请到此下载:http://api.dllzj.com/search/search.aspx?name=microsoft.office.interop.excel.dll

将Textbox控件里的数据导入Excel(windowsForm中):

      

/// <summary>
       /// 把数据导入到Excel中
       /// </summary>
       /// <param name="sender"></param>
       /// <param name="e"></param>
        private void button2_Click(object sender, EventArgs e)
        {
            SaveFileDialog sfd = new SaveFileDialog();
            sfd.DefaultExt = "xls";    //设置默认扩展名为xls
            sfd.Filter = "Excel文件(*.xls)|*.xls";//另存文件时文件类型框中出现的内容
            if (sfd.ShowDialog() == DialogResult.OK)  //获取选定的另存文件对话框存在
            {
                DoExport(this.textBox2, sfd.FileName);
            }
        }
        private void DoExport(TextBox textbox, string strFileName)
        {
           // string[] lines = System.Text.RegularExpressions.Regex.Split(textbox.Text, "/r/n");
          //  int rowNum = lines.Length;//获取 TextBox2控件里的数据行数
            int rowNum=textbox.Lines.Length; //读取Textbox控件里数据的行数
            int rowIndex = 1;   //定义一个Excel行
            int col = 1;        //定义一个Excel列,默认为1
            if (rowNum == 0 || string.IsNullOrEmpty(strFileName)) //控件里没有数据
            {
                return;
            }
            if (rowNum > 0)//控件里有数据
            {
                Microsoft.Office.Interop.Excel.Application xlApp = new Microsoft.Office.Interop.Excel.ApplicationClass();
                if (xlApp == null)
                {
                    MessageBox.Show("无法创建Excel对象,可能您的系统未安装Excel");
                    return;
                }
                xlApp.DefaultFilePath = "";
                xlApp.DisplayAlerts = true;
                xlApp.SheetsInNewWorkbook = 1;
                Microsoft.Office.Interop.Excel.Workbook xlBook = xlApp.Workbooks.Add(true);
                for (int i = 0; i < rowNum; i++)//将数据导入Excel
                {
                    string ss = textbox.Lines[i].ToString();  //读取相对应行的数据,这里只是测试用
                    rowIndex++;
                    xlApp.Cells[rowIndex,col] = Convert.ToString(textbox.Lines[i].ToString()) + "\t";//读取到的Textbox控件里的数据导入到Excel
                    //xlApp.Rows[rowIndex,0] = Convert.ToString(textbox.Lines[i].ToString()) + "\t";
                }
                xlBook.SaveAs(strFileName, Microsoft.Office.Interop.Excel.XlFileFormat.xlWorkbookNormal, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlExclusive, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);
                xlApp = null;
                xlBook = null;
                MessageBox.Show("数据导入成功!!");
            }
           

        }

 

将listview控件里的数据导入Excel中:

 

/// <summary>
        /// 执行导出数据
        /// </summary>
        public void ExportToExecl()
        {
            System.Windows.Forms.SaveFileDialog sfd = new SaveFileDialog();
            sfd.DefaultExt = "xls";
            sfd.Filter = "Excel文件(*.xls)|*.xls";
            if (sfd.ShowDialog() == DialogResult.OK)
            {
                DoExport(this.lstPostion, sfd.FileName);
            }
        }
        /// <summary>
        /// 具体导出的方法
        /// </summary>
        /// <param name="listView">ListView</param>
        /// <param name="strFileName">导出到的文件名</param>
        private void DoExport(ListView listView, string strFileName)
        {
            int rowNum = listView.Items.Count;
            int columnNum = listView.Items[0].SubItems.Count;
            int rowIndex = 1;
            int columnIndex = 0;
            if (rowNum == 0 || string.IsNullOrEmpty(strFileName))
            {
                return;
            }
            if (rowNum > 0)
            {

                Microsoft.Office.Interop.Excel.Application xlApp = new Microsoft.Office.Interop.Excel.ApplicationClass();
                if (xlApp == null)
                {
                    MessageBox.Show("无法创建excel对象,可能您的系统没有安装excel");
                    return;
                }
                xlApp.DefaultFilePath = "";
                xlApp.DisplayAlerts = true;
                xlApp.SheetsInNewWorkbook = 1;
                Microsoft.Office.Interop.Excel.Workbook xlBook = xlApp.Workbooks.Add(true);
                //将ListView的列名导入Excel表第一行
                foreach (ColumnHeader dc in listView.Columns)
                {
                    columnIndex++;
                    xlApp.Cells[rowIndex, columnIndex] = dc.Text;
                }
                //将ListView中的数据导入Excel中
              //  xlApp.Cells[rowIndex, columnIndex] = Convert.ToString(this.textBox1.Text.Trim());
                for (int i = 0; i < rowNum; i++)
                {
                    rowIndex++;
                    columnIndex = 0;
                    for (int j = 0; j < columnNum; j++)
                    {
                        columnIndex++;
                        //注意这个在导出的时候加了“\t” 的目的就是避免导出的数据显示为科学计数法。可以放在每行的首尾。
                        xlApp.Cells[rowIndex, columnIndex] = Convert.ToString(999999) + "\t";
                    }
                }
                //例外需要说明的是用strFileName,Excel.XlFileFormat.xlExcel9795保存方式时 当你的Excel版本不是95、97 而是2003、2007 时导出的时候会报一个错误:异常来自 HRESULT:0x800A03EC。 解决办法就是换成strFileName, Microsoft.Office.Interop.Excel.XlFileFormat.xlWorkbookNormal。
                xlBook.SaveAs(strFileName, Microsoft.Office.Interop.Excel.XlFileFormat.xlWorkbookNormal, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlExclusive, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);
                xlApp = null;
                xlBook = null;
                MessageBox.Show("OK");
            }
        }
