Question

I’m trying to convert a Base64String back to an Image. I have this code set up in my C# console application.

public Image Base64ToImage(string base64String)
{
    // Convert Base64 String to byte[]
    byte[] imageBytes = Convert.FromBase64String(base64String);
    MemoryStream ms = new MemoryStream(imageBytes, 0, imageBytes.Length);

    // Convert byte[] to Image
    ms.Write(imageBytes, 0, imageBytes.Length);
    Image image = Image.FromStream(ms, true);
    return image;
}

I’m getting an error each time I use the type Image. It says:

The type or namespace name could not be found.

I’m using:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;
using System.Threading.Tasks;
using System.Net.Mime;
using System.Drawing;

Am I missing a library?

Yes, if you’re writing a console application, your project probably won’t include a reference to System.Drawing.dll, which is the assembly containing System.Drawing.Image. Just add the assembly reference, and it should be fine.
