小编New*_*ary的帖子

我试图使用http post从asp.net发布一些数据到webservice.

这样做我得到了封闭的错误.我检查过很多帖子,但没有什么可以帮助我.对此的任何帮助将非常感谢.

Length ='dataStream.Length'引发了类型'System.NotSupportedException'的异常

Position ='dataStream.Position'引发了类型'System.NotSupportedException'的异常

随函附上我的代码:

public XmlDocument SendRequest(string command, string request)
{
    XmlDocument result = null;

    if (IsInitialized())
    {
        result = new XmlDocument();

        HttpWebRequest webRequest = null;
        HttpWebResponse webResponse = null;

        try
        {
            string prefix = (m_SecureMode) ? "https://" : "http://";
            string url = string.Concat(prefix, m_Url, command);

            webRequest = (HttpWebRequest)WebRequest.Create(url);
            webRequest.Method = "POST";
            webRequest.ContentType = "text/xml";
            webRequest.ServicePoint.Expect100Continue = false;

            string UsernameAndPassword = string.Concat(m_Username, ":", m_Password);
            string EncryptedDetails = Convert.ToBase64String(Encoding.ASCII.GetBytes(UsernameAndPassword));

            webRequest.Headers.Add("Authorization", "Basic " + EncryptedDetails);

            using (StreamWriter sw …

我收到StreamWriter抛出的错误,我收到的消息是:

Length = '(sw.BaseStream).Length' threw an exception of type 'System.NotSupportedException'
Position = '(sw.BaseStream).Position' threw an exception of type 'System.NotSupportedException'
