    将Textbox控件里的数据导入Excel(windowsForm中):

                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

                        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);

    将listview控件里的数据导入Excel中:

                }
            }
            /// <summary>
            /// 具体导出的方法

            /// <param name="listView">ListView</param>

                    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");
                }
            }
