保存到數據庫的文件路徑，只保存文件名

Question

好吧所以我一直在尋找所有來到這個小小的代碼，並得到幾乎所有的工作。我可以上傳圖像並將其保存到創建的文件夾中。我可以保存其他值傳遞給數據庫。我現在的問題是，我想保存到數據庫的文件路徑，所以我可以調用它來在另一個頁面上顯示圖像。出於某種原因，它只會保存正在上傳的圖像名稱，而不是路徑。

當我調試一下，看看所有的獲得通過，當我的手錶添加到 file.SaveAs(pathLoc);

表達進行了評估，並沒有值無效

這裏是我的代碼「VE使用齋

控制器

[HttpPost] 
    [ValidateAntiForgeryToken] 
    public ActionResult Create(ImageInfo info, HttpPostedFileBase file) 
    { 
     if (ModelState.IsValid) 
     { 
      if (file != null) 
      { 
       var pic = Path.GetFileName(file.FileName); 
       var pathLoc = Path.Combine(Server.MapPath("~/Uploads/") + pic); 
       file.SaveAs(pathLoc); 


       info.ImagePath = file.FileName; 
       db.SaveChanges(); 
      } 

      return RedirectToAction("Index"); 
     } 

     return View(info); 
    } 

查看

<h2>Create</h2> 


@using (Html.BeginForm("Create", "ImageInfoes", null, FormMethod.Post,  new { enctype = "multipart/form-data" })) 
{ 
    @Html.AntiForgeryToken() 
    @Html.ValidationSummary(true) 

<div class="form-horizontal"> 
    <h4>ImageInfo</h4> 
    <hr /> 
    @Html.ValidationSummary(true, "", new { @class = "text-danger" }) 

    <div class="form-group"> 
     @Html.LabelFor(model => model.ImageName, htmlAttributes: new { @class = "control-label col-md-2" }) 
     <div class="col-md-10"> 
      @Html.EditorFor(model => model.ImageName, new { htmlAttributes = new { @class = "form-control" } }) 
      @Html.ValidationMessageFor(model => model.ImageName, "", new { @class = "text-danger" }) 
     </div> 
    </div> 
    <div class="form-group"> 
     @Html.LabelFor(model => model.ImageSize, htmlAttributes: new { @class = "control-label col-md-2" }) 
     <div class="col-md-10"> 
      @Html.EditorFor(model => model.ImageSize, new { htmlAttributes = new { @class = "form-control" } }) 
      @Html.ValidationMessageFor(model => model.ImageSize, "", new { @class = "text-danger" }) 
     </div> 
    </div> 
    <div class="form-group"> 
     @Html.LabelFor(model => model.ImagePath, htmlAttributes: new { @class = "control-label col-md-2" }) 
     <div class="col-md-10"> 
      <input id="ImagePath" title="Upload a product image" type="file" name="file" /> 
     </div> 
    </div> 
    <div class="form-group"> 
     <div class="col-md-offset-2 col-md-10"> 
      <input type="submit" value="Create" class="btn btn-default" /> 
     </div> 
    </div> 
</div> 
} 

    <div> 
     @Html.ActionLink("Back to List", "Index") 
    </div> 

型號

public partial class ImageInfo 
    { 
     public byte id { get; set; } 
     public string ImageName { get; set; } 
     public Nullable<long> ImageSize { get; set; } 
     public string ImagePath { get; set; } 
    } 

任何將有助於充分。

如果需要，您需要將完整路徑組合爲文件路徑和文件名。

Console.WriteLine(Path.Combine(System.Reflection.Assembly.GetExecutingAssembly().Location, System.IO.Path.GetRandomFileName())); 

C：\用戶\ 02483695 \文件\的Visual Studio 2015 \項目\ ConsoleApplication5 \缺點 oleApplication5 \ BIN \調試\ ConsoleApplication5.exe \ tv1k1uev.jsq

以下還您可以找到關於文件，文件目錄，文件路徑和文件擴展名的示例。

System.IO.FileInfo fileInfo = new FileInfo("filename.file"); 
var fileDirectory = fileInfo.DirectoryName; 
var fileName = fileInfo.Name; 
var fileExtension = fileInfo.Extension; 
var filePathandFileNameBoth = fileInfo.FullName; 

Console.WriteLine("filePathandFileNameBoth: "); 
Console.WriteLine(filePathandFileNameBoth); 
Console.WriteLine("-"); 
Console.WriteLine("fileDirectory:"); 
Console.WriteLine(fileDirectory); 
Console.WriteLine("-"); 
Console.WriteLine("fileName:"); 
Console.WriteLine(fileName); 
Console.WriteLine("-"); 
Console.WriteLine(filePathandFileNameBoth == fileDirectory + "\\" + fileName ? fileExtension : "I'm totally wrong"); 
Console.ReadLine(); 

結果：
