I have a Fileupload that I select several files and I save it in the directory, but I noticed that FileBytes of it, it also repeats in all the files.

if (FileUp.HasFiles)
            {
                foreach (HttpPostedFile uploadedFile in FileUp.PostedFiles)
                {

                    Arquivo arq = new Arquivo();
                    ArquivoVersao arqVersao = new ArquivoVersao();
                    //seta as propriedades de arquivo

                    arq.XARQUIVO = Path.GetFileName(uploadedFile.FileName);
                    arq.EXTENSAO = Path.GetExtension(uploadedFile.FileName);

                      arq.ARQUIVOBYTE = FileUp.FileBytes;
                    FileUp.SaveAs(Server.MapPath("~/db_arquivos/") + arq.XARQUIVO);
    } 
  }

aspx:

 <div class="modal fade open" id="myModal" role="dialog" aria-labelledby="myModalLabel">
                        <div class="modal-dialog">

                            <div class="modal-content">
                                <div class="modal-header" >
                                    <button type="button" class="close" data-dismiss="modal"  aria-hidden="true">&times;</button>
                                    <h4 class="modal-title">
                                        <asp:Label ID="lblModalTitle" runat="server" Text="Enviar arquivos"></asp:Label></h4>
                                </div>
                                <div class="modal-body">
                                    <asp:FileUpload ID="FileUp" AllowMultiple="true" runat="server" />
                                    <br />

                             <input type="text" class="form-control" id="tokenfield" value="red,green,blue" />



                                </div>
                                <div class="modal-footer">
                                    <asp:Button runat="server" CssClass="btn ui-icon-cancel small" ID="UpluodButton" OnClick="UploadButton_Click" Text="Enviar" />

                                </div>
                            </div>

                        </div>
                    </div>

My fileUpload is fired here:

  ScriptManager.RegisterStartupScript(Page, Page.GetType(), "myModal", "$('#myModal').modal();", true);

The name, extension, etc. always comes right, but FileBytes always gets the size of the first file, summarizing the file is saved equally.

Use the InputStream property of the uploadedFile object, according to Microsoft documentation this property exposes a Stream of the uploaded file, so we can use a BinaryReader to read the bytes of the file.

if (FileUp.HasFiles)
{
    foreach (HttpPostedFile uploadedFile in FileUp.PostedFiles)
    {
        Arquivo arq = new Arquivo();
        ArquivoVersao arqVersao = new ArquivoVersao();

        //seta as propriedades de arquivo
        arq.XARQUIVO = Path.GetFileName(uploadedFile.FileName);
        arq.EXTENSAO = Path.GetExtension(uploadedFile.FileName);

        // Utilizando o BinaryReader para obter os bytes do objeto HttpPostedFile
        BinaryReader b = new BinaryReader(uploadedFile.InputStream);
        arq.ARQUIVOBYTE = b.ReadBytes(uploadedFile.ContentLength);

        FileUp.SaveAs(Server.MapPath("~/db_arquivos/") + arq.XARQUIVO);
    }
}
