     if (file != null && file.ContentLength > 0) 
     { 
      // extract only the fielname 
      var fileName = Path.GetFileName(file.FileName); 
      // store the file inside ~/App_Data/uploads folder 
      var path = Path.Combine(Server.MapPath("~/App_Data/uploads"), fileName); 
      file.SaveAs(path); 
     } 

     if (ModelState.IsValid) 
     {

@using (Html.BeginForm()) { 
@Html.ValidationSummary(true) 
<fieldset> 
    <legend>Hobbies</legend> 

    <div class="editor-label"> 
     @Html.LabelFor(model => model.hobbiename) 
    </div> 
    <div class="editor-field"> 
     @Html.EditorFor(model => model.hobbiename) 
     @Html.ValidationMessageFor(model => model.hobbiename) 
    </div> 

    <div class="editor-label"> 
     @Html.LabelFor(model => model.filelocation) 
    <input type="file" name="file"/> 

    </div> 
    <div class="editor-label"> 
     @Html.LabelFor(model => model.hobbydetail) 
    </div> 
    <div class="editor-field"> 
     @Html.EditorFor(model => model.hobbydetail) 
     @Html.ValidationMessageFor(model => model.hobbydetail) 
    </div> 

    <p> 
     <input type="submit" value="Create" />

</fieldset> 
} 

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

據我知道這是不可能得到直接的URL到一個文件中App_Data文件夾（文件夾保護，使得可以保存例如數據庫文件）。您需要將其上傳到其他文件夾（例如~/Uploads）。然後你可以像這樣構建URL：string url = "http://yourwebsite.com/Uploads/" + filename;並將它存儲在你的模型中。
