关于Webservice的基础部分不做赘述，下面贴上我的测试代码（属于动态调用Webservice）：

1：http助手类

using System.Net;
using System.Text;
using System.Web;
using static System.Net.Mime.MediaTypeNames;namespace WebServiceGetWeather;public class HttpHelper
{private static HttpHelper m_Helper;/// <summary>/// 单例模式/// </summary>public static HttpHelper Helper{get { return m_Helper ?? (m_Helper = new HttpHelper()); }}/// <summary>/// 获取请求的数据/// </summary>/// <param name="strUrl">请求地址</param>/// <param name="requestMode">请求方式</param>/// <param name="parameters">参数</param>/// <param name="requestCoding">请求编码</param>/// <param name="responseCoding">响应编码</param>/// <param name="timeout">请求超时时间（毫秒）</param>/// <returns>请求成功响应信息，失败返回null</returns>public string GetResponseString(string strUrl, ERequestMode requestMode,  Dictionary<string,string> parameters, Encoding requestCoding, Encoding responseCoding, int timeout = 300){string url = VerifyUrl(strUrl);HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(new Uri(url));HttpWebResponse webResponse = null;switch (requestMode){case ERequestMode.Get:webResponse = GetRequest(webRequest, timeout);break;case ERequestMode.Post:webResponse = PostRequest(webRequest, parameters, timeout, requestCoding);break;}if (webResponse != null && webResponse.StatusCode == HttpStatusCode.OK){using (Stream newStream = webResponse.GetResponseStream()){if (newStream != null)using (StreamReader reader = new StreamReader(newStream, responseCoding)){string result = reader.ReadToEnd();return result;}}}return null;}/// <summary>/// get 请求指定地址返回响应数据/// </summary>/// <param name="webRequest">请求</param>/// <param name="timeout">请求超时时间（毫秒）</param>/// <returns>返回：响应信息</returns>private HttpWebResponse GetRequest(HttpWebRequest webRequest, int timeout){try{webRequest.Accept = "text/html, application/xhtml+xml, application/json, text/javascript, */*; q=0.01";webRequest.Headers.Add("Accept-Language", "zh-cn,en-US,en;q=0.5");webRequest.Headers.Add("Cache-Control", "no-cache");webRequest.UserAgent = "DefaultUserAgent";//webRequest.ContentType = "application / json";webRequest.Timeout = timeout;webRequest.Method = "GET";// 接收返回信息HttpWebResponse webResponse = (HttpWebResponse)webRequest.GetResponse();return webResponse;}catch (Exception ex){return null;}}/// <summary>/// post 请求指定地址返回响应数据/// </summary>/// <param name="webRequest">请求</param>/// <param name="parameters">传入参数</param>/// <param name="timeout">请求超时时间（毫秒）</param>/// <param name="requestCoding">请求编码</param>/// <returns>返回：响应信息</returns>private HttpWebResponse PostRequest(HttpWebRequest webRequest, Dictionary<string, string> parameters, int timeout, Encoding requestCoding){try{// 拼接参数string postStr = string.Empty;if (parameters != null){parameters.All(o =>{if (string.IsNullOrEmpty(postStr))postStr = string.Format("{0}={1}", HttpUtility.UrlEncode(o.Key), HttpUtility.UrlEncode(o.Value));elsepostStr += string.Format("&{0}={1}", HttpUtility.UrlEncode(o.Key), HttpUtility.UrlEncode(o.Value));return true;});}byte[] byteArray = requestCoding.GetBytes(postStr);webRequest.Accept = "text/html, application/xhtml+xml, application/json, text/javascript, */*; q=0.01";webRequest.Headers.Add("Accept-Language", "zh-cn,en-US,en;q=0.5");webRequest.Headers.Add("Cache-Control", "no-cache");webRequest.UserAgent = "DefaultUserAgent";//webRequest.Timeout = timeout;webRequest.ContentType = "application/x-www-form-urlencoded";webRequest.ContentLength = byteArray.Length;webRequest.Method = "POST";// 将参数写入流using (Stream newStream = webRequest.GetRequestStream()){newStream.Write(byteArray, 0, byteArray.Length);newStream.Close();}// 接收返回信息HttpWebResponse webResponse = (HttpWebResponse)webRequest.GetResponse();return webResponse;}catch (Exception ex){return null;}}/// <summary>/// 验证URL/// </summary>/// <param name="url">待验证 URL</param>/// <returns></returns>private string VerifyUrl(string url){if (string.IsNullOrEmpty(url))throw new Exception("URL 地址不可以为空！");if (url.StartsWith("http://", StringComparison.CurrentCultureIgnoreCase))return url;return string.Format("http://{0}", url);}
}
public enum ERequestMode
{Get,Post
}

2：调用方法

internal class Program{static void Main(string[] args){Console.WriteLine("Hello, World!");TestInvoke();}/// <summary>/// 测试调用/// </summary>static void TestInvoke(){//组织参数//<参数名，参数值>Dictionary<string, string> parameters = new Dictionary<string, string>();parameters.Add("byProvinceName", "北京");//getSupportCity是方法名称直接放在后面string url = "http://www.webxml.com.cn/WebServices/WeatherWebService.asmx/getSupportCity ";string _result = HttpHelper.Helper.GetResponseString(url, ERequestMode.Post, parameters, Encoding.Default, Encoding.UTF8);}

注意事项：

1：接口方法里面的案例参数要与代码中指定的一致：

 2：方法名直接放在url结尾：

string url = "http://www.webxml.com.cn/WebServices/WeatherWebService.asmx/getSupportCity ";

△   其中getSupportCity 就是方法名。

Dictionary<string, string> parameters = new Dictionary<string, string>();

△   其中parameters 的key是方法参数名，value是参数值。
