我在通过将二进制数据发布到服务器时遇到问题HttpWebRequest。这是我的客户端代码：

var request = (HttpWebRequest)WebRequest.Create(uri);
request.Method = "POST";
request.UserAgent = RequestUserAgent;
request.ContentType = "application/x-www-form-urlencoded";
var responseStr = "";
var dataStr = Convert.ToBase64String(data);
var postData = Encoding.UTF8.GetBytes(
string.Format("uploadid={0}&chunknum={1}&data={2}", uploadId, chunkNum, dataStr));
using (var dataStream = request.GetRequestStream())
{
    dataStream.Write(postData, 0, postData.Length);
    dataStream.Close();
}

然后我想通过 MVC 控制器处理请求，这是它的签名：

public ActionResult UploadChunk(Guid? uploadID, int? chunkNum, byte[] data)

但我这里有错误，说 data 不是 Base64 编码的数组，我做错了什么？
