Save image to database using ASP.NET MVC

Question

I am trying to save an image to a database using the Create method. but when trying this code I get this error:

Input is not a valid Base-64 string because it contains a non-basic 64 character, more than two padding characters, or a white space among padding characters. *

I am very new to MVC. I will be very grateful for the answer, Thank you very much in advance.

        var upload = Request.Files["ImageData"];
        if (upload.ContentLength > 0)
        {
            string savedFileName = Path.Combine(
                  ConfigurationManager.AppSettings["FileUploadDirectory"],

Web.config:

<appSettings>
    <add key="FileUploadDirectory" value="~/Resources/images/customers/" />
</appSettings>

Writing to the database:

Column Name  Data Type  Allow Nulls
ImageData    image      yes

Try the following:

string savedFileName = Server.MapPath("/Resources/images/customers/" + "customers_" + saveCustomer.FirstName + "_" + saveCustomer.LastName + ".jpg");

instead

string savedFileName = Path.Combine(
                      ConfigurationManager.AppSettings["FileUploadDirectory"],
                      "customers_" + saveCustomer.FirstName + "_" + saveCustomer.LastName + ".jpg");

• If your client models contain an Image field, you do not need to save it to server-side Dirs.

private byte[] ImageToBytes(Image img, ImageFormat format)
{            
 MemoryStream mstream = new MemoryStream();
 img.Save(mstream, format);
 mstream.Flush();
 return mstream.ToArray();
}
