1、添加组件:Microsoft.Office.Interop.Excel
步骤:右键点击“引用”--->添加引用--->COM--->Microsoft.Office.Interop.Excel--->点击“确定”
2、创建一个ExportExcel类,该类作用是:将ListView中的数据导出到Excel表格中
代码如下:
using Microsoft.Office.Interop.Excel; using System; using System.Collections.Generic; using System.IO; using System.Linq; using System.Text; using System.Threading.Tasks; using System.Windows.Forms; namespace CustomerManager { class ExportExcel { //导出方法 public void ExcelExport(ListView lv,string fileName) { int rowNum = lv.Items.Count; int column = lv.Items[0].SubItems.Count; int rowIndex = 1; int columnIndex = 0; if (rowNum == 0 || string.IsNullOrEmpty(fileName)) { return; } if (rowNum > 0) { Microsoft.Office.Interop.Excel.Application xlApp = new Microsoft.Office.Interop.Excel.Application(); if (xlApp == null) { MessageBox.Show("无法创建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表的第一行 foreach (ColumnHeader dc in lv.Columns) { columnIndex++; xlApp.Cells[rowIndex, columnIndex] = dc.Text; } //将ListView中的数据导入到Excel中 for (rowIndex = 2; rowIndex < lv.Items.Count + 2; rowIndex++) { xlApp.Cells[rowIndex, 1] = lv.Items[rowIndex - 2].Text; for (columnIndex = 2; columnIndex <= lv.Columns.Count; columnIndex++) { xlApp.Cells[rowIndex, columnIndex] = lv.Items[rowIndex - 2].SubItems[columnIndex - 1].Text; } } //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(fileName, 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("导出成功!"); } } } }
主窗体中调用:
//执行导出数据 public void ExportData() { if (this.saveFileDialog1.ShowDialog() == DialogResult.OK) { ExportExcel ee = new ExportExcel(); ee.ExcelExport(this.lvwCustomer, saveFileDialog1.FileName); } }
最后在点击事件中调用!
