Problem when deleting image

I have an image that is my user’s avatar, then I need to delete and I have the following code snippets:

Action that is used in file import

public void MinhaActionParaImport()
{
    var arquivo = Request.Files[0];
    var caminho = Path.Combine(Server.MapPath("~/Minha/Pasta/"), "foto.jpg");
    arquivo.SaveAs(caminho);
}

Method used to remove the image

public void DeletarImagem()
{
    var imagem = Path.Combine(Server.MapPath("~/Minha/Pasta/"), "foto.jpg");
    if (System.IO.File.Exists(imagem))
        System.IO.File.Delete(imagem);
}

Method used to display the image

public ActionResult ExibirImagem()
{
    Image image = Image.FromFile(Path.Combine(Server.MapPath("~/Minha/Pasta/"), "foto.jpg"));
    ImageCodecInfo codec = ImageCodecInfo.GetImageDecoders().First(c => c.FormatID == image.RawFormat.Guid);
    return File(Path.Combine(Server.MapPath("~/Minha/Pasta/"), "foto.jpg"), codec.MimeType);
}

View

<img src="@Url.Action("ExibirImagem")"/>

When trying to do this, I get the following error:

The process cannot access the file because it is being used by Another process

What can I do to force the deletion of this image?

  • Usually it is the .vshost that holds the file pointers. How did you upload the file?

  • @Gypsy Heart Mendez, I used the SaveAs() of HttpPostedFileBase.

  • Can you put the full code in the question, please?

  • I made the changes.

  • The message indicates that this file is open in some other application. It may be in your ASP.NET MVC application or outside it. Your code is ok.

  • It’s probably in my MVC application. If it’s being displayed on the page during deletion, can’t the operation be done? Is there any way to force this?

    You open the image before then? If yes, you can again edit your question and put the code?

  • Add all relevant code to image manipulation.

  • I added the code and saw the problem, I was opening one Image without the using. If you want to come up with a legal answer, feel free. If you don’t, I’ll do it later.

    @Filipeoliveira No need. Your answer is great. + 1.

The problem occurred by opening the image without closing.

In the code snippet:

public ActionResult ExibirImagem() 
{
    Image image = Image.FromFile(Path.Combine(Server.MapPath("~/Minha/Pasta/"), "foto.jpg"));
    ImageCodecInfo codec = ImageCodecInfo.GetImageDecoders().First(c = > c.FormatID == image.RawFormat.Guid);
    return File(Path.Combine(Server.MapPath("~/Minha/Pasta/"), "foto.jpg"), codec.MimeType);
}

Should be like this:

public ActionResult ExibirImagem() 
{
    string mimeType;
    using(Image image = Image.FromFile(Path.Combine(Server.MapPath("~/Minha/Pasta/"), "foto.jpg"))) 
    {
        ImageCodecInfo codec = ImageCodecInfo.GetImageDecoders().First(c = > c.FormatID == image.RawFormat.Guid);
        mimeType = codec.MimeType;
    }
    return File(Path.Combine(Server.MapPath("~/Minha/Pasta/"), "foto.jpg"), mimeType);
}
