我有一个交通繁忙的aspx页面，呼吁每个user`s请求的Web服务如下：

I have a heavy traffic aspx page calling a web service upon every user`s request as follows.

string uri = "Path.asmx";
string soap = "soap xml string";

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(uri);
request.Headers.Add("SOAPAction", "\"http://xxxxxx"");
request.ContentType = "text/xml;charset=\"utf-8\"";
request.Accept = "text/xml";
request.Method = "POST";

using (Stream stm = request.GetRequestStream())
{
    using (StreamWriter stmw = new StreamWriter(stm))
    {
        stmw.Write(soap);
    }
}
WebResponse response = request.GetResponse();
response.close();

一切工作正常，但有时我收到以下错误。

Everything is working fine but sometimes I am getting the following error.

远程服务器返回错误：（500）内部服务器错误。    在System.Net.HttpWebRequest.GetResponse（）

The remote server returned an error: (500) Internal Server Error. at System.Net.HttpWebRequest.GetResponse()

有谁对这个错误的任何想法或任何人可以告诉我，如果我做错了。

Does anybody have any idea about this error or can anybody tell me if I am doing wrong.

感谢您

推荐答案

我终于摆脱内部服务器错误消息，具有以下code。不知道是否有另一种方式来实现这一目标。

Finally I get rid of internal server error message with the following code. Not sure if there is another way to achieve it.

string uri = "Path.asmx";
string soap = "soap xml string";

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(uri);
request.Headers.Add("SOAPAction", "\"http://xxxxxx"");
request.ContentType = "text/xml;charset=\"utf-8\"";
request.Accept = "text/xml";
request.Method = "POST";

using (Stream stm = request.GetRequestStream())
{
    using (StreamWriter stmw = new StreamWriter(stm))
    {
        stmw.Write(soap);
    }
}

using (WebResponse webResponse = request.GetResponse())
{
}
