Question

I found the following code but unable to understand what should I pass through ImageToBase64(Image image, System.Drawing.Imaging.ImageFormat format).

I need a FileUpload tool to upload an image to system and to pass it to ImageToBase64

For reference my code is

public string ImageToBase64(Image image, System.Drawing.Imaging.ImageFormat format)
    {
        using (MemoryStream ms = new MemoryStream())
        {
            image.Save(ms, format);
            byte[] imageBytes = ms.ToArray();
            string base64String = Convert.ToBase64String(imageBytes);
            return base64String;
        }
    }

I tried doing ImageToBase64(FileUpload.FileBytes, "Image/PNG") But I am getting syntax error. What’s the correct syntax that I can use to this code?

Answer 1

Because the function takes argument of type Image and ImageFormat, and you are passing in byte[] and string.

You don’t need mime type, and you would only need the

var base64String = Convert.ToBase64String(FileUpload.FileBytes);
