下面是我读取现有excel文件的代码:

FileInfo newFile = new FileInfo("C:\\Excel\\SampleStockTakeExceptionReport.xlsx");
using (ExcelPackage xlPackage = new ExcelPackage(newFile))
{
    var ws = xlPackage.Workbook.Worksheets.Add("Content");
    ws.View.ShowGridLines = false;
    ws.Column(4).OutlineLevel = 1;
    ws.Column(4).Collapsed = true;
    ws.Column(5).OutlineLevel = 1;
    ws.Column(5).Collapsed = true;
    ws.OutLineSummaryRight = true;
    //Headers
    ws.Cells["B1"].Value = "Name";
    ws.Cells["C1"].Value = "Size";
    ws.Cells["D1"].Value = "Created";
    ws.Cells["E1"].Value = "Last modified";
    ws.Cells["B1:E1"].Style.Font.Bold = true;
    System.Diagnostics.Process.Start("C:\\Excel\\SampleStockTakeExceptionReport.xlsx");
}

我运行代码时.它会引发运行时错误.
错误.

## Deployment


1. If you don't have an userDefineLang.xml file already, you can drop this file among your other configuration file, in the Notepad++ Install Folder. It should be named userDefineLang.xml.
2. Otherwise, open both the existing and new file.
    - Select all of the new file, …

我可以使用perl将excel文件保存为.csv,如下所示:

print "Content-type: application/vnd.ms-excel\n";
print "Content-Disposition: attachment;filename=\"file name.xls\"\n\n";    
print"Fruits, Cost";       

#Then循环结果.

但我需要将其保存为.xls因为我想使用颜色.任何人都可以帮忙吗？

我是Mongo DB的新手.我正在尝试按照本教程在我的笔记本电脑中安装MongoDB .我按照教程中的命令启动MongoDb并进行连接.当我开始连接时, C:\mongodb\bin\mongo.exe 它会提示新的CMD并说它连接到:test,但它保持这么长时间.感谢有些人可以就此提出建议.
