因为项目需要在导出数据到EXECL文档的同时还需要导出图片进去,在处理是遇到的一些问题,在此记录一下。
首先代码写好之后放测试服务器上去执行的时候报错了,报检索 COM 类工厂中 CLSID 为 {00024500-0000-0000-C000-000000000046} 的组件时失败,原因是出现以下错误: 80070005。
这个解决方法我基本上是按照网上来进行解决的,但是需要注意的就是,设置完权限之后,还需要在服务器安装的office文件夹分配权限。
权限问题设置完之后就是调试代码了,网上搜索到的资料都是先插入数据,然后在数据的最后插入图片,而不是我想要的每一行都有图片,所以不符合我的需求,于是就自己看着网上的代码整吧整吧。
/// <summary>/// /// </summary>/// <param name="dt">数据源</param>/// <param name="filepath">文件路劲例如(E:\\Execl\\201706070001.xls)</param>protected void ExportExcel(DataTable dt, string filepath) {if (dt == null || dt.Rows.Count == 0) return; Microsoft.Office.Interop.Excel.Application xlApp = new Microsoft.Office.Interop.Excel.Application();object m_objOpt = System.Reflection.Missing.Value;if (xlApp == null) {return; }//System.Globalization.CultureInfo CurrentCI = System.Threading.Thread.CurrentThread.CurrentCulture;System.Threading.Thread.CurrentThread.CurrentCulture = new System.Globalization.CultureInfo("en-US"); Microsoft.Office.Interop.Excel.Workbooks workbooks = xlApp.Workbooks; Microsoft.Office.Interop.Excel.Workbook workbook = workbooks.Add(Microsoft.Office.Interop.Excel.XlWBATemplate.xlWBATWorksheet); Microsoft.Office.Interop.Excel.Worksheet worksheet = (Microsoft.Office.Interop.Excel.Worksheet)workbook.Worksheets[1]; Microsoft.Office.Interop.Excel.Range range;long totalCount = dt.Rows.Count;long rowRead = 0;for (int i = 0; i < dt.Columns.Count; i++) { worksheet.Cells[1, i + 1] = dt.Columns[i].ColumnName; range = (Microsoft.Office.Interop.Excel.Range)worksheet.Cells[1, i + 1]; range.Interior.ColorIndex = 15; }for (int r = 0; r < dt.Rows.Count; r++) {for (int i = 0; i < dt.Columns.Count; i++) {try{if (i == 4) { range = worksheet.get_Range("E" + (r + 2), m_objOpt); //这里是因为我要给文档的E列插入图片,所以加了判断,并写死了E列 range.Select();float PicLeft, PicTop; PicLeft = Convert.ToSingle(range.Left); PicTop = Convert.ToSingle(range.Top); range.ColumnWidth = 60;//设置单元格的宽 range.RowHeight = 120;//设置单元格的高worksheet.Shapes.AddPicture(dt.Rows[r][i].ToString(), Microsoft.Office.Core.MsoTriState.msoFalse, Microsoft.Office.Core.MsoTriState.msoCTrue, PicLeft, PicTop, 100, 100);//这后面的100 是设置图片的宽高 }elseworksheet.Cells[r + 2, i + 1] = dt.Rows[r][i].ToString(); }catch{ worksheet.Cells[r + 2, i + 1] = dt.Rows[r][i].ToString().Replace("=", ""); } } rowRead++; } xlApp.Visible = true; workbook.Saved = true; workbook.SaveAs(filepath); workbook.Close(true, Type.Missing, Type.Missing); workbook = null; xlApp.Quit(); xlApp = null; }
