如何从 .NET WebClient 反序列化包含 HTTP POST 参数的字节数组

Question

我正在使用 WebClient 向远程 URL 发送 HTTP POST 请求，如下所示：

byte[] responsebytes = client.UploadValues(
                        "https://www.jaja.com/yadayadayada", "POST", reqparm);
responsebody = Encoding.UTF8.GetString(responsebytes);

URL 以 HTTP POST 参数的形式给出响应，例如：

"Status=Ok&BrowserUrl=http%3a%2f%2fwww.jaja.com%3a7106%2fxxx&Hash=8614C21DD93749339906DB35C51B06006B33DC8C192F40DFE2DB6549942C837C4452E1D1333DE9DB7814B278C8B9E3C34D1A76D2F937DEE57502336E0A071412"

我在这里面临的问题是如何将此响应序列化到一个对象 class:

public class PaynowResponseModel : PayNowBase
    {
        public string browserurl { get; set; }
        public string pollurl { get; set; }
        public string status { get; set; }
        public string hash { get; set; }
    }

我试过下面的方法

public static object ByteArrayToObject(Byte[] buffer)
        {
            BinaryFormatter formatter = new BinaryFormatter();
            MemoryStream stream = new MemoryStream(buffer);
            object rval = formatter.Deserialize(stream);
            stream.Close();
            return rval;
        }

我是这样称呼的：

var responseObj = (PaynowResponseModel) General.ByteArrayToObject(responsebytes);

但它不起作用。我在 ByteArrayToObject 方法

中遇到异常

System.Runtime.Serialization.SerializationException was caught
HResult=-2146233076 Message=The input stream is not a valid binary format. The starting contents (in bytes) are: 73-74-61-74-75-73-3D-4F-6B-26-62-72-6F-77-73-65-72 ...

请帮助我如何解决这个问题或实现我的目标的替代方法。

提前谢谢你:)

您不能直接反序列化字节数组，因为字节数组不是有效的 PayNowResponseModel 序列化对象。

使用 HttpUtility.ParseQueryString(Encoding.UTF8.GetString(responsebytes)) 将检索到的字符串解析为 NameValueCollection，然后创建一个转换器将数据转换为 PayNowResponseModel 对象。 [您可能需要添加对 System.Web]

的引用

看看下面的示例：

        var resp = HttpUtility.ParseQueryString(responsebytes);
        var converted = new PaynowResponseModel();
        converted.browserurl = resp["BrowserUrl"];
        converted.status = resp["Status"];
        converted.hash = resp["Hash"];
