How to show CrystalReport as and Download it in MVC

As there is no way till now to show crystal report in a view(MVC). You can simply convert the report document as pdf using following code:

 public void ShowReport()
        {
            List<ToDos> lstTodos = new List<ToDos>();
            lstTodos = db.ToDos.ToList();
            ReportDocument rd = new ReportDocument();
            rd.Load(Path.Combine(Server.MapPath("CrystalReport1.rpt")));
            rd.SetDataSource(lstTodos);
            Stream stream;
            stream = rd.ExportToStream(CrystalDecisions.Shared.ExportFormatType.PortableDocFormat);

            byte[] binarydata;
            binarydata = new Byte[stream.Length];
            stream.Read(binarydata, 0, (int)stream.Length);

            string base64String = "";
            try
            {
                base64String =
                  System.Convert.ToBase64String(binarydata,
                                         0,
                                         binarydata.Length);
            }
            catch (System.ArgumentNullException)
            {
                System.Console.WriteLine("Binary data array is null.");

            }

            string pdfurl = "data:application/pdf;base64," + base64String;

            ViewBag.Url = pdfurl;

        }

And after converting it as PDF use HTML object tag to show pdf document as shown below(using ViewBag.Url):

@{
    ViewBag.Title = "Index";
    Layout = "~/Views/Shared/_Layout.cshtml";
}

<object data="@ViewBag.Url"
        type="application/pdf" style=" height: 991px;margin-left: -32%;margin-top: 5%;width: 98%;"></object>
