用C#快速往Excel写数据

用C#快速往Excel写数据

  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;
