将ListView中的内容倒入到Excel

本示例是用于将ListView中的内容倒入到Excel,与常用的逐单元格写不同的是,本例子采用数据写入到range的方法。该方法效率明显较高。

 Excel.Application   app   =   new   Excel.ApplicationClass();
  if(   app   ==   null)
  {
  MessageBox.Show( "Excel无法启动 ");
  return;
  }
  app.Visible   =   true;
  Excel.Workbooks   wbs   =   app.Workbooks;
  Excel.Workbook   wb   =   wbs.Add(Missing.Value);
  Excel.Worksheet   ws   =   (Excel.Worksheet)wb.Worksheets[1];
  Excel.Range   r   =   ws.get_Range( "A1 ", "H1 ");
  object   []   objHeader   =   { "标题1 ", "标题2 ", "标题3 ",
   "标题4 ", "标题5 ", "标题6 ",
   "标题7 ", "标题8 "};
  r.Value   =   objHeader;
  if   (lv.Items.Count   > 0)
  {
  r   =   ws.get_Range( "A2 ",Missing.Value);    
  object   [,]   objData   =   new   Object[this.lv.Items.Count,8];
  foreach(ListViewItem   lvi   in   lv.Items)
  {
  objData[lvi.Index,0]   =   lvi.Text;
  objData[lvi.Index,1]   =   lvi.SubItems[1].Text;
  objData[lvi.Index,2]   =   lvi.SubItems[2].Text;
  objData[lvi.Index,3]   =   lvi.SubItems[3].Text;
  objData[lvi.Index,4]   =   lvi.SubItems[4].Text;
  objData[lvi.Index,5]   =   lvi.SubItems[5].Text;
  objData[lvi.Index,6]   =   lvi.SubItems[6].Text;
  objData[lvi.Index,7]   =   lvi.SubItems[7].Text;
  }
  r   =   r.get_Resize(lv.Items.Count,8);
  r.Value   =   objData;
  r.EntireColumn.AutoFit();  
  }
  app   =   null;


不知道有没有用,转载至csdn的一个blog。没有使用ADO只是用了Excel的com组件。
