如果我想将文件存储到服务器/路径文件夹中，并且在数据库中我只想存储路径名/字符串，如何存储文件。
您可以上传文件并将其 url 保存在数据库表中，如下所示：
View:
@using(Html.BeginForm("Create","Assignment",FormMethod.Post,new {enctype="multipart/form-data"}))
{
...
<div class="editor-field">
<%: Html.TextBoxFor(model => model.FileLocation, new { type="file"})%>
<%: Html.ValidationMessageFor(model => model.FileLocation) %>
</div>
...
}
Action:
[HttpPost]
public ActionResult Create(Assignment assignment)
{
if (ModelState.IsValid)
{
if(Request.Files.Count > 0)
{
HttpPostedFileBase file = Request.Files[0];
if (file.ContentLength > 0)
{
var fileName = Path.GetFileName(file.FileName);
assignment.FileLocation = Path.Combine(
Server.MapPath("~/App_Data/uploads"), fileName);
file.SaveAs(assignment.FileLocation);
}
db.Assignments.Add(assignment);
db.SaveChanges();
return RedirectToAction("Index");
}
}
return View(assignment);
}
