Question

我正在为我的Web服务使用WCF SOAP服务，我想从Web服务返回一个文件作为流，问题是文件数据最终在肥皂信封中，我不希望我只想要文件要返回的流，有人可以请帮助这是我现在所拥有的。

   [OperationContract]
   Stream GetDocument();

    public Stream GetDocument()
    {
        string filePath = @"C:/Temp/test.txt";
        try
        {

            System.IO.FileInfo fileInfo = new System.IO.FileInfo(filePath);
            System.IO.FileStream stream = new System.IO.FileStream(filePath, System.IO.FileMode.Open, System.IO.FileAccess.Read);
            return stream;
        }
        catch (Exception ex)
        {
            throw ex;
        }
    }

的web.config
