如何從Chrome中保存ASP.NET MVC中的文件？

Question

我想從使用AjaxSubmit的chrome保存文件。我得到了Chrome以八位字節格式發送文件的問題，並且我無法檢查它是否是真正的圖像或其他內容。

當我嘗試打電話

HttpPostedFileBase file 

file.InputStream 

的InputStream造成鉻錯誤Parameter is not valid.

如何我可以將它們保存在asp.net C＃

Answer 1

我在我看來，用這個：<input type="file" id="deploymentPackage" name="deploymentPackage" />

而在我的控制器中，我這樣做：

public ActionResult AddRelease(ApplicationReleaseViewModel appRelease, HttpPostedFileBase deploymentPackage) 
     { 
      if (ModelState.IsValid) 
      { 
       ApplicationRelease dto = new ApplicationRelease(); 
       appRelease.UpdateDto(dto); 

       using (StreamReader sr = new StreamReader(deploymentPackage.InputStream)) 
       { 
        dto.DeploymentPackage = new byte[deploymentPackage.InputStream.Length]; 
        deploymentPackage.InputStream.Read(dto.DeploymentPackage, 0, dto.DeploymentPackage.Length); 
       } 

       this.ApplicationService.AddApplicationRelease(dto); 

       return RedirectToAction("Index", new { ActionPerformed = "ApplicationReleaseAdded", Name = appRelease.Name.CutToMaxLength(50).UrlEncode() }); 
      } 
      else 
      { 
       ViewBag.PostAction = "AddRelease"; 

       return View("EditRelease", appRelease); 
      } 
     }
