Object reference not set to an instance of an object (byte[]

Question

Hello,

I have the following code:

public byte[] getFile(FileUpload file)
    {
        byte[] bytes=null;

        using (Stream fs = file.PostedFile.InputStream)
        {
            using (BinaryReader br = new BinaryReader(fs))
            {
                bytes = br.ReadBytes((Int32)fs.Length);
            }
        }
        return bytes;
    }

 When I compile the procedure I get the following error message: "Object reference not set to an instance of an object."

 

Any idea how to fix the error?

 

Thank you in advance.
