我是网络新手。这是我的SELECT *
FROM `nhrd_members` B
WHERE Membership_Number LIKE 'A%'
AND `Member_FromDate` >= '2014-01-01'
AND `Member_FromDate` <= '2015-01-01' where id not in (SELECT id
FROM `nhrd_members` A
WHERE Membership_Number LIKE 'A%'
AND `Member_FromDate` >= '2014-01-01'
AND `Member_FromDate` <= '2014-05-14');
:
action
问题:我知道在Request.Files中只能有一个文件。是否有任何方法可以在没有[HttpPost]
public virtual ActionResult SaveFile(IEnumerable<VacationSchedule.Models.VacationTypeViewModel> vacationTypes)
{
foreach (string fileName in Request.Files)
{
HttpPostedFileBase file = Request.Files[fileName];
string type = file.ContentType;
string nameAndLocation = "~/Documents/" + System.IO.Path.GetFileNameWithoutExtension(file.FileName);
file.SaveAs(Server.MapPath(nameAndLocation));
}
return View(MVC.Admin.ActionNames.Documents);
}
周期的情况下获取此文件?

您可以使用FirstOrDefault
扩展名方法:
string fileName = Request.Files.Cast<HttpPostedFile>().FirstOrDefault();
if (!string.IsNullOrEmpty(fileName))
{
}
或者只是带有索引访问器的三元运算符:
string fileName = Request.Files.Count > 0 ? Request.Files[0] : null;

获取名为file的第一个元素的索引/键:
var imagem = Request.Files[Request.Files.GetKey(0)];
