如何使用流发送字符串

Question

我正在查看用于传输数据的流的示例

string infoAsString = "blablabla";
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
            byte[] requestBytes = System.Text.Encoding.ASCII.GetBytes(message);
            request.Method = "POST";
            request.ContentType = "text/xml;charset=utf-8";
            request.ContentLength = requestBytes.Length;
            using (Stream requestStream = request.GetRequestStream())
            {      
                //pass infoAsString?
                requestStream.Write(requestBytes, 0, requestBytes.Length);
                requestStream.Close();
            }

//然后我可以抓住它..

public object Upload(string infoAsString)
    {

请建议....谢谢您的任何答复

您可以使用request.Headers集合：

string infoAsString = "blablabla";
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
byte[] requestBytes = System.Text.Encoding.ASCII.GetBytes(message);
request.Method = "POST";
request.ContentType = "text/xml;charset=utf-8";
request.ContentLength = requestBytes.Length;
request.Headers.Add(string.format("infoAsString: {0}", infoAsString))
using (Stream requestStream = request.GetRequestStream())
{      
    requestStream.Write(requestBytes, 0, requestBytes.Length);
    requestStream.Close();
}
