将Excel文件导出到视图(MVC) [英] Exporting Excel File to View (MVC)

问题描述

我必须将数据导出为Excel，实际上我已经实现了，但是我怀疑何时 使用

I have to Export Data to View as Excel , Actually I have Implemented,but my doubt is when to use

return new FileContentResult(fileContents, "application/vnd.ms-excel");

与

return File(fileContents, "application/vnd.ms-excel");

以及如何在每种方法中设置可下载文件名"?

and How can set Downloadable Filename in each of this methods?

示例1:

public ActionResult ExcelExport()
{
   byte[] fileContents = Encoding.UTF8.GetBytes(data);
   return new FileContentResult(fileContents, "application/vnd.ms-excel");
}

示例:2

public ActionResult ExcelExport()
{
   byte[] fileContents = Encoding.UTF8.GetBytes(data);
   return File(fileContents, "application/vnd.ms-excel");
}

推荐答案

您可以了解FileContentResult& FileResult在这里: ASP.NET MVC中有四个文件结果

You can read about the differences between FileContentResult & FileResult here : What's the difference between the four File Results in ASP.NET MVC

您可以这样指定文件名

return new FileContentResult(fileContents, "application/vnd.ms-excel") { FileDownloadName = "name.xls" };

// or

// note that this call will return a FileContentResult object
return new File(fileContents, "application/vnd.ms-excel", "name.xls");
