Question

我认为我的问题很简单，但我正在努力解决它。当我上传图像文件时，它工作正常，但数据库上的路径是物理路径，如 C：// user / pictures / blabla .... 。我想将其更改为虚拟路径（〜/...)。当我手动将数据库路径更改为虚拟路径时，图像将被显示。在此先感谢您的帮助。这是我的代码：

CONTROLLER

public ActionResult Create(DriverReg model, HttpPostedFileBase file)
        {
            if (ModelState.IsValid)
            {
                if (file != null && file.ContentLength > 0)
                {
                    var fileName = Path.GetFileName(file.FileName);
                    var phisicalPath = Path.Combine(Server.MapPath("~/Content/uploads/"), fileName);
                    file.SaveAs(phisicalPath);
                    DriverReg newRecord = new DriverReg();
                    newRecord.FullName = model.FullName;
                    newRecord.Address = model.Address;
                    newRecord.Postcode = model.Postcode;
                    newRecord.Contact = model.Contact;
                    newRecord.Email = model.Email;
                    newRecord.County = model.County;
                    newRecord.File = phisicalPath;
                    newRecord.Date = DateTime.Now;

                    db.DriverRegs.Add(newRecord);
                    db.SaveChanges();
                    return RedirectToAction("Index");
                }
            }

            return View(model);
        }

创建视图

<div class="form-group">
                @Html.LabelFor(model => model.File, htmlAttributes: new { @class = "control-label col-md-2" })
                <div class="col-md-10">
                    <input type="file" class="file-input" name="file" />
                    @Html.ValidationMessageFor(model => model.File, "", new { @class = "text-danger" })
                </div>
            </div>

DETAILS VIEW

 <dt>
                @Html.DisplayNameFor(model => model.File)
            </dt>

            <dd>
                @Html.Image(@Model.File, "image")
            </dd>

Answer 1

在您调用Server.MapPath之前存储虚拟路径，然后在数据库记录中使用它。

var fileName = Path.GetFileName(file.FileName);
var combinedVirtualPath = Path.Combine("~/Content/uploads", fileName);
var phisicalPath = Server.MapPath(combinedVirtualPath);
file.SaveAs(phisicalPath);
DriverReg newRecord = new DriverReg();
newRecord.FullName = model.FullName;
newRecord.Address = model.Address;
newRecord.Postcode = model.Postcode;
newRecord.Contact = model.Contact;
newRecord.Email = model.Email;
newRecord.County = model.County;
newRecord.File = combinedVirtualPath;
newRecord.Date = DateTime.Now;

Answer 2

如何将虚拟路径分配给变量？

var fileName = Path.GetFileName(file.FileName);
var destination = $"~/Content/uploads/{fileName}";
var physicalPath = Server.MapPath(destination);
file.SaveAs(physicalPath);

然后只存储 目的地 变量的内容

Answer 3

var phisicalPath = Path.Combine(("~/Content/uploads/"), fileName);

或

string filePath = @"~/Content/uploads/"
var phisicalPath = Path.Combine(filePath, fileName);

将物理路径存储在数据库而不是虚拟路径上
