How to convert image to base 64 c# string?

  • 772

I have this method to convert an image to a base 64 string and then assign it from JQuery to an image type tag... but I realized that it is only encoding the path of the image, when I decode I get something like this:

ClientApp/dist/assets/ProfileImageGirls/Avatar_56106a30-ce82-452e-9bfc-3861a1fc9069.JPG

How can I solve it?

Method:

   public string CodeBase64(string path)
        {
            string cadenaBase64 = string.Empty;
            using (Image image = Image.FromFile(path))
            {
                using (MemoryStream m = new MemoryStream())
                {
                    image.Save(m, image.RawFormat);
                    byte[] imageBytes = m.ToArray();
                    cadenaBase64 = Convert.ToBase64String(imageBytes);
                }
            }

            return cadenaBase64;
        }
c#

    I tried the code you posted and it works.

    In case it is of interest, I share the code that I use to convert any file to Base64.

    public string CodificaBase64(string path)
{
    using (FileStream fileStream = File.OpenRead(path))
    using (MemoryStream memoryStream = new MemoryStream())
    {
        fileStream.CopyTo(memoryStream);
        return Convert.ToBase64String(memoryStream.ToArray());
    }
}
