    ContentLength 是 -1

    我的C#API调用和流生成: 

    var stream = new MemoryStream();
serializer.Serialize(stream, toSend);

HttpClientHandler handler = new HttpClientHandler()
{
    AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate
};
HttpClient client = new HttpClient(handler);

HttpResponseMessage response = await 
    client.PostAsync("https://api.opentransportdata.swiss/trias",
            new StringContent(new StreamReader(stream, 
                Encoding.UTF8).ReadToEnd(), Encoding.UTF8, "text/xml"));

    stream 是一个 MemoryStream
    响应消息是 200
    下面是我发送的序列化XML数据,我从流中读取的方式与读取它以将其发送到API的方式相同
