#C: Convert images from Google's Firebase database as text to images on the file system

Question

I'm migrating data from a Google Firebase database to the .net platform and this db has a lot of images. I get them from firebase in json format which is text and need to convert them to image files. I have attached a sample of one of the images. Note: all images start with "/9j/". Not sure what this is. All images were created from iOS and Android devices. What would be the c# code to do this?

Thanks.

You can do something like :
(I added "==" to get a correct string and I get a valid JPG, but a partial image from your sample file...)

{
    var sText = System.IO.File.ReadAllText(@"C:\Users\Christian\Downloads\imagetext.txt");
    sText += "==";
    string sDestFile = @"e:\test\testimage.jpg";
    var bytes = Convert.FromBase64String(sText);
    using (var fs = new FileStream(sDestFile, FileMode.Create))
    {
        fs.Write(bytes, 0, bytes.Length);
        fs.Flush();
    } 
}
