一、创建action
public class importController : BaseController
{
private IWebHostEnvironment _hostingEnvironment = null;
public importController(IWebHostEnvironment hostingEnvironment )
{
_hostingEnvironment = hostingEnvironment;
}
public IActionResult downLoadMuban()
{
string path = _hostingEnvironment.ContentRootPath + "/Up/muban.xls";
var stream = System.IO.File.OpenRead(path);
string fileExt = System.IO.Path.GetExtension(path);
//获取文件的ContentType
var provider = new FileExtensionContentTypeProvider();
var memi = provider.Mappings[fileExt];
return File(stream, memi, Path.GetFileName(path));
}
}
二、创建超链接
<a href="/import/downLoadMuban">模板</a>
完成！！
