示例：調用webservice查詢IP地址信息

webservice地址：http://www.wjg121.cn/Service/IPAddress.asmx?op=GetIPCountryAndLocal

static void Main(string[] args)
{


//構造soap請求信息
StringBuilder soap = new StringBuilder();
soap.Append("<?xml version=\"1.0\" encoding=\"utf-8\"?>");
soap.Append("<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">");
soap.Append("<soap:Body>");
soap.Append("<GetIPCountryAndLocal xmlns=\"http://tempuri.org/\">");
soap.Append("<RequestIP>183.39.119.90</RequestIP>");
soap.Append("</GetIPCountryAndLocal>");
soap.Append("</soap:Body>");
soap.Append("</soap:Envelope>");

string url = "http://www.wjg121.cn/Service/IPAddress.asmx";
Console.WriteLine(WebServiceUtility.GetSOAPReSource(url,soap.ToString()));
Console.ReadKey();

}

//返回結果：

<?xml version="1.0" encoding="utf-8"?><soap:Envelope xmlns:soap="http://schemas.
xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance
