Convert Base64 String to an Image File and Save it to File System?

Question

I am trying to make a.Net 6 console application that would take in a base64string and then save it to the file system as an actual image file

Example

I have this image

I would have this image already as a base64 string.

Now I want to save to my file system as "cat-1285634_960_720.png"

I just can't figure out how to do it. All the examples I see say to use Image.Save() but I can't find that in.Net6 and looks like it is removed.

Answer 1

First convert the base64 string to a byte array and then use File.WriteAllBytes(...) to save it:

byte[] imageByteArray = Convert.FromBase64String(base64String);

File.WriteAllBytes("image.png", imageByteArray);
