返回多个MemoryStream作为HttpResponseMessage

public HttpResponseMessage GetMultipleStreams()
{
    // 创建多个MemoryStream
    List<MemoryStream> streams = new List<MemoryStream>();

    // 添加第一个MemoryStream
    MemoryStream stream1 = new MemoryStream();
    // 在stream1中写入数据
    // ...

    streams.Add(stream1);

    // 添加第二个MemoryStream
    MemoryStream stream2 = new MemoryStream();
    // 在stream2中写入数据
    // ...

    streams.Add(stream2);

    // 创建HttpResponseMessage
    HttpResponseMessage response = new HttpResponseMessage(HttpStatusCode.OK);

    // 设置响应内容为多个MemoryStream
    MultipartContent content = new MultipartContent();

    foreach (var stream in streams)
    {
        // 将每个MemoryStream添加到MultipartContent中
        var streamContent = new StreamContent(stream);
        content.Add(streamContent);
    }

    // 将MultipartContent设置为HttpResponseMessage的内容
    response.Content = content;

    return response;
}
