converting image into byte[] asp.net mvc

Question

I need to store the image in my database in byte[]

I am sending the image from Javascript to mvc controller using ajax

In my javascript

var files = $("#MyImage").get(0).files;
formData.append('files', files);

in my MVC Controller

using (var binaryReader = new BinaryReader(Request.Files[0].InputStream))
{
        fileData = binaryReader.ReadBytes(Request.Files[0].ContentLength);
}

Is it a correct way to store the image or I am doing this wrong?

please suggest

You can post HttpPostedFileBase on your razor.

if (upload != null)
{
    using (var inputStream = upload.InputStream)
    {
        var memoryStream = inputStream as MemoryStream;
        if (memoryStream == null)
        {
            memoryStream = new MemoryStream();
            inputStream.CopyTo(memoryStream);
        }
        var data = memoryStream.ToArray();
}

The method signature should be like this

[HttpPost]
public ActionResult Foo(HttpPostedFileBase upload)
{
}

And your razor side:

@using (Html.BeginForm("Foo", "ControllerName", FormMethod.Post, new { @enctype = "multipart/form-data" }))
{

}
