How to make the input stream content to be copied to the output stream in azure func

Question

Hello,

I have the following azure function which use imperativ binding. The writer

write json data to the output stream which works fine. Instead of write json data I would rather use the same contents the exist in the input stream which is xml data.

So from the input stream I want to copy the content to the output stream.

public void Run(
            [BlobTrigger("input/{name}.xml")] Stream inputBlob,
            IBinder binder,
            string name, ILogger log)
        {
            XmlDocument doc = new XmlDocument();
            doc.Load(inputBlob);

            string json = jsonHandling.Convert(doc);
            json = jsonHandling.Clean(json);

            using (var writer = binder.Bind<TextWriter>(new BlobAttribute(
                    $"output/a6109523-a23b-47ed-9732-40ea4535c82f {DateTime.Now.ToString("yyyy-MM-dd hh:mm:ss")}.json", FileAccess.Write)))
            {
                writer.Write(json);
            };
        }

Many thanks in advance

I have added a sample code please check if it works for you

if not I can work on this in more detail

public void Run(
    [BlobTrigger("input/{name}.xml")] Stream inputBlob,
    IBinder binder,
    string name, ILogger log)
{
    using (var outputBlob = binder.Bind<Stream>(new BlobAttribute(
        $"output/a6109523-a23b-47ed-9732-40ea4535c82f {DateTime.Now.ToString("yyyy-MM-dd hh:mm:ss")}.xml", FileAccess.Write)))
    {
        inputBlob.CopyTo(outputBlob);
    };
}
