How Can I Convert a Base64 String to an Image and Save It?

Converting a Base 64 String to an Image and Saving It

When attempting to convert a base 64 string into an image using the provided code, it may not function correctly because the code is designed to download and save an image from a URL. To address this issue and process base 64 strings, consider the following approach:

Modify the code to receive a base 64 string as a parameter. Once converted to an image, it can be saved using the image.Save(...) method.

public Image LoadImage(string base64String)
{
    byte[] bytes = Convert.FromBase64String(base64String);

    Image image;
    using (MemoryStream ms = new MemoryStream(bytes))
    {
        image = Image.FromStream(ms);
    }

    return image;
}

Handle potential exceptions. For instance, if the bytes represent a bitmap, a "A generic error occurred in GDI ." exception may occur. To work around this, save the image before disposing the memory stream (while still within the using statement):

image.Save("output.png", ImageFormat.Png);

Now, with these modifications, you can seamlessly convert base 64 strings into images and save them to your desired location.
