  How to post pictures to controller

  Feb 12, 2021 03:56 AM|aaarianme|LINK

  I save pictures as byte[] in the database. Im familiar with the HttpPostedFileBase  in asp.net but they got rid of that in .net Core 5 apparently How can I send the uploaded picture to the controller which converts it into picture and inserts into the database?

  <input name="UploadedPic" type="file"readonly />
  <button type="submit">Submit</button>
  

  C# controller

  public IActionResult UploadPictures()
      {
  
          return null;
  
      }

  You have to use IFormFile Interface of Asp.Net Core 5.0 

  You can define a DTO class with an IFormFile property, and use in combination with form having enctype - multipart/form-data

  public class UploadModel
  {
     public IFormFile UploadedPic { get; set; }
  }

  <form method="post" enctype="multipart/form-data" asp-controller="Home" asp-action="Index">
     <input asp-for="UploadedPic" />
     <button type="submit">Submit</button>
  </form>

  [HttpPost]         
  public IActionResult Index(UploadModel model)         
  {              
       // Here you can read the posted file stream from the request or copy it...          
       var stream = model.UploadedPic.OpenReadStream();               
       return View();         
  }
