本文介绍了一个使用C#通过GET方法调用WebService并返回字符串的方法。该方法构造了一个HTTP请求，并读取了返回的XML数据，最终提取出文本节点作为返回结果。

C#通过Get方式调用Web Service返回一个字符串，可以带参数访问
public string getServiceResult(string serviceUrl) {
HttpWebRequest HttpWReq;
HttpWebResponse HttpWResp;
HttpWReq = (HttpWebRequest)WebRequest.Create(serviceUrl);
HttpWReq.Method = "GET";
HttpWResp = (HttpWebResponse)HttpWReq.GetResponse();
if (HttpWResp.StatusCode == HttpStatusCode.OK)
{
//Consume webservice with basic XML reading, assumes it returns (one) string
XmlReader reader = XmlReader.Create(HttpWResp.GetResponseStream());
while (reader.Read())
{
reader.MoveToFirstAttribute();
if (reader.NodeType == XmlNodeType.Text)
{
return reader.Value;
}
}
return String.Empty;
}
else
{
throw new Exception("Error on remote IP to Country service: "+ HttpWResp.StatusCode.ToString());
}
}
