将图像转换为二进制文件，返回System.byte []而不是asp.net中的二进制格式

Question

I'm trying to convert image to binary and then store in database. I have a code to do this and after several Google searches, most answers are like the code I have written. The error I have is that instead of seeing a binary format in my database I'm getting System.byte[] as output. I also debugged and got the same thing. Here's part of the code

if (Upload.HasFile)
{
    HttpPostedFile postedFile = Upload.PostedFile;
    string filename = Path.GetFileName(postedFile.FileName);
    string fileExtension = Path.GetExtension(filename);
    int filesize = postedFile.ContentLength;
    if (fileExtension.ToLower() == ".jpg")
    {
        Stream stream = postedFile.InputStream;
        BinaryReader binaryreader = new BinaryReader(stream);

        byte[] bytes = binaryreader.ReadBytes((int)stream.Length);

        Debug.WriteLine(bytes);
    }
}

The result of my debug gives System.byte[] as output.

Answer 1

You can convert a byte array to string for DB storage

var storedString = Convert.ToBase64String(bytes);

and get the byte array from the stored string

bytes = Convert.FromBase64String(storedString);

If you really want to use the Binary format, you can look into the SoapHexBinary class, particularly the Parse() method and Value property
