如何上傳ASP.NET MVC中的圖像？

Question

如何上傳圖像以進入ASP.NET MVC 3.0中的~/Content/Images？

Answer 1

如果你想在ASP.NET MVC中上傳圖片，請嘗試以下問題：

• Simple Image Upload in ASP.NET MVC
• Uploading an image in ASP.NET MVC

如果你想使用ASP.NET控件上傳圖像，這打破了MVC關注的分離。有upload helpers available。

Answer 2

HTML文件上傳ASP MVC 3

型號：（注意FileExtensionsAttribute是MvcFutures可用它會驗證文件擴展名的客戶端和服務器端。）

public class ViewModel 
{ 
    [Required, Microsoft.Web.Mvc.FileExtensions(Extensions = "csv", ErrorMessage = "Specify a CSV file. (Comma-separated values)")] 
    public HttpPostedFileBase File { get; set; } 
} 

HTML查看：

@using (Html.BeginForm("Action", "Controller", FormMethod.Post, new { enctype = "multipart/form-data" })) 
{ 
    @Html.TextBoxFor(m => m.File, new { type = "file" }) 
    @Html.ValidationMessageFor(m => m.File) 
} 

控制器動作：

[HttpPost] 
public ActionResult Action(ViewModel model) 
{ 
    if (ModelState.IsValid) 
    { 
     // Use your file here 
     using (MemoryStream memoryStream = new MemoryStream()) 
     { 
      model.File.InputStream.CopyTo(memoryStream); 
     } 
    } 
}
