System.Net.WebException：获取响应流ReadDone2时出错

问题描述

|| 尝试将代码移植到mono时出现以下错误。它在Windows中运行良好，甚至可以在Linux中编译。 当我使用HttpWebRequest时（一个按钮调用对流执行写操作的方法，等等），它将引发此错误。

System.Net.WebException: Error getting response stream (ReadDone2): ReceiveFailure ---> System.Exception:    
   at System.Net.WebConnection.HandleError(WebExceptionStatus st,System.Exception e,System.String where)
   at System.Net.WebConnection.ReadDone(IAsyncResult result)
   at System.Net.Sockets.Socket+SocketAsyncResult.Complete()
   at System.Net.Sockets.Socket+Worker.Receive()

该代码是

        HttpWebRequest oRequest;
        PostData pData = new PostData();
        Encoding encoding = Encoding.UTF8;
        Stream oStream = null;

        byte[] buffer;

        if (!isLoggedIn)

        {

            oRequest = (HttpWebRequest)HttpWebRequest.Create(\"http://www.ksl.com/public/member/signin\");

            oRequest.CookieContainer = cookieJar;
            oRequest.ContentType = \"multipart/form-data; boundary=\" + PostData.boundary;

            oRequest.Method = \"POST\";
            pData.Params.Add(new PostDataParam(\"MAX_FILE_SIZE\",\"50000000\",PostDataParamType.Field));

            pData.Params.Add(new PostDataParam(\"dado_form_3\",\"1\",PostDataParamType.Field));

            pData.Params.Add(new PostDataParam(\"member[email]\",Properties.Settings.Default.txtusername,PostDataParamType.Field));

            pData.Params.Add(new PostDataParam(\"member[password]\",Properties.Settings.Default.txtpassword,PostDataParamType.Field));

            pData.Params.Add(new PostDataParam(\"x\",\"0\",PostDataParamType.Field));
            pData.Params.Add(new PostDataParam(\"y\",PostDataParamType.Field));
            byte[] buff = encoding.GetBytes(pData.GetPostData());
            oRequest.ContentLength = buff.Length;
            oStream = oRequest.GetRequestStream();
            oStream.Write(buff,buff.Length);


            oRequest.GetResponse().GetResponseStream();

            isLoggedIn = true;

        }

类PostData的定义如下：

public class PostData
{
    // Change this if you need to,not necessary
    public static string boundary = \"AaB03x\";

    private List<PostDataParam> m_Params;

    public List<PostDataParam> Params
    {
        get { return m_Params; }
        set { m_Params = value; }
    }

    public PostData()
    {
        m_Params = new List<PostDataParam>();
    }

    /// <summary>
    /// Returns the parameters array formatted for multi-part/form data
    /// </summary>
    /// <returns></returns>
    public string GetPostData()
    {
        StringBuilder sb = new StringBuilder();
        foreach (PostDataParam p in m_Params)
        {
            sb.AppendLine(\"--\" + boundary);

            if (p.Type == PostDataParamType.File)
            {
                sb.AppendLine(string.Format(\"Content-Disposition: file; name=\\\"{0}\\\"; filename=\\\"{1}\\\"\",p.Name,p.FileName));
                sb.AppendLine(\"Content-Type: application/octet-stream\");
                sb.AppendLine();
                sb.AppendLine(p.Value);
            }
            else
            {


                sb.AppendLine(string.Format(\"Content-Disposition: form-data; name=\\\"{0}\\\"\",p.Name));
                sb.AppendLine();
                sb.AppendLine(p.Value);
            }
        }

        sb.AppendLine(\"--\" + boundary + \"--\");

        return sb.ToString();
    }
}

public enum PostDataParamType
{
    Field,File
}

public class PostDataParam
{
    public PostDataParam(string name,string value,PostDataParamType type)
    {
        Name = name;
        Value = value;
        Type = type;
    }

    public PostDataParam(string name,string filename,PostDataParamType type)
    {
        Name = name;
        Value = value;
        FileName = filename;
        Type = type;
    }

    public string Name;
    public string FileName;
    public string Value;
    public PostDataParamType Type;
}
