Context.Response.Body read stream .net

public async Task Invoke(HttpContext context)
    {
        //Workaround - copy original Stream
        var initalBody = context.Request.Body;

        using (var bodyReader = new StreamReader(request.Body))
        {
            string body = await bodyReader.ReadToEndAsync();
            //Do something with body
            //Replace write only request body with read/write memorystream so you can read from it later

               request.Body = new MemoryStream(Encoding.UTF8.GetBytes(body));

        //handle other middlewares
        await _next.Invoke(context);

        //Workaround - return back to original Stream
        context.Request.Body = initalBody;
