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;
