How to convert base64 string to FormFile

Note: I am currently working on the api part of the app and I have no access to the frontend stuff.

So the frontend will send me a base64 string that I need to convert to a FormFile because the method that would upload files in s3 will only accept IFormFileCollection so I will need to convert the base64 string to a Formile and also it's too complicated to just refactor the whole upload method now.

Is there a way to do this?

Thanks!

something like

File.WriteAllBytes(@"c:\yourfile", Convert.FromBase64String(yourBase64String));

using (var stream = File.OpenRead(@"c:\yourfile"))
{
    var formFileName = new FormFile(stream, 0, stream.Length, null, Path.GetFileName(stream.Name))
    {
        Headers = new HeaderDictionary(),
        ContentType = "YOUR CONTENT TYPE HERE"
    };
}
