c# - 在 ByteRangeStreamContent 中获取字节范围和直接从字节数组中剪切字节有什么区别

Question

我想知道在获取字节范围内容ByteRangeStreamContent和直接从字节数组中获取字节范围是否有任何区别

所以基本上我想问一下以下两个代码是否有任何区别，就接收方将收到的结果而言response

byte[] bytes = firmwareFile.Content;;
var stream = new MemoryStream(bytes);
var content = new ByteRangeStreamContent(stream, Request.Headers.Range, contentType);
var response = new HttpResponseMessage
                         {
                             Content = content
                         };
result.StatusCode = HttpStatusCode.PartialContent;

和

if (Request.Headers.Range != null)
{
    var range = Request.Headers.Range.Ranges.OfType<RangeItemHeaderValue>().First();

    if(range.From.HasValue && range.To.HasValue)
    {
        var from = (int)range.From.Value;
        var to = (int)range.To.Value;

        bytes = firmwareFile.Content.Skip(from).Take(to - from).ToArray();
    }
}

var stream = new MemoryStream(bytes);
var content = new ByteArrayContent(stream.ToArray());
var response = new HttpResponseMessage
                             {
                                 Content = content
                             };
response.Content.Headers.ContentType = contentType;
result.StatusCode = HttpStatusCode.PartialContent;

另外，第二个版本正确吗？我可以使用它吗
