关于webservice 远程调用、、 两个服务器 利用 webservice远程 获取数据 在类里面写了 webservice调用的方法 两个服务器的webservice的引用是需要 同步的是吗、、、就是个服务器如果有一个方法那另外一个 也应该有是吗、 解决方案 » 免费领取超大流量手机卡,每月29元包185G流量+100分钟通话, 中国电信官方发货 /// <summary> /// 动态调用web服务 /// /// 调用示例 /// string url = "http://www.webservicex.net/globalweather.asmx"; /// string[] args = new string[2]; /// args[0] = "shenzhen"; /// args[1] = "China"; /// object result = WebServiceHelper.InvokeWebService(url ,"GetWeather" ,args); /// this.label_Result.Text = result.ToString(); /// </summary> /// <param name="url"></param> /// <param name="methodname"></param> /// <param name="args"></param> /// <returns></returns> public static object InvokeWebService(string url, string methodname, object[] args) { return WebServiceHelper.InvokeWebService(url, null, methodname, args); } public static object InvokeWebService(string url, string classname, string methodname, object[] args) { string @namespace = "EnterpriseServerBase.WebService.DynamicWebCalling"; if ((classname == null) || (classname == "")) { classname = WebServiceHelper.GetWsClassName(url); } try { //获取WSDL WebClient wc = new WebClient(); Stream stream = wc.OpenRead(url + "?WSDL"); ServiceDescription sd = ServiceDescription.Read(stream); ServiceDescriptionImporter sdi = new ServiceDescriptionImporter(); sdi.AddServiceDescription(sd, "", ""); CodeNamespace cn = new CodeNamespace(@namespace); //生成客户端代理类代码 CodeCompileUnit ccu = new CodeCompileUnit(); ccu.Namespaces.Add(cn); sdi.Import(cn, ccu); CSharpCodeProvider csc = new CSharpCodeProvider(); ICodeCompiler icc = csc.CreateCompiler(); //设定编译参数 CompilerParameters cplist = new CompilerParameters(); cplist.GenerateExecutable = false; cplist.GenerateInMemory = true; cplist.ReferencedAssemblies.Add("System.dll"); cplist.ReferencedAssemblies.Add("System.XML.dll"); cplist.ReferencedAssemblies.Add("System.Web.Services.dll"); cplist.ReferencedAssemblies.Add("System.Data.dll"); //编译代理类 CompilerResults cr = icc.CompileAssemblyFromDom(cplist, ccu); if (true == cr.Errors.HasErrors) { System.Text.StringBuilder sb = new System.Text.StringBuilder(); foreach (System.CodeDom.Compiler.CompilerError ce in cr.Errors) { sb.Append(ce.ToString()); sb.Append(System.Environment.NewLine); } throw new Exception(sb.ToString()); } //生成代理实例,并调用方法 System.Reflection.Assembly assembly = cr.CompiledAssembly; Type t = assembly.GetType(@namespace + "." + classname, true, true); object obj = Activator.CreateInstance(t); System.Reflection.MethodInfo mi = t.GetMethod(methodname); return mi.Invoke(obj, args); } catch (Exception ex) { throw new Exception(ex.InnerException.Message, new Exception(ex.InnerException.StackTrace)); } } private static string GetWsClassName(string wsUrl) { string[] parts = wsUrl.Split('/'); string[] pps = parts[parts.Length - 1].Split('.'); return pps[0]; } #endregion public static string GetRealUrl(string pUrl) { string appPath = "/"; if (HttpContext.Current.Request.ApplicationPath != appPath) { appPath = HttpContext.Current.Request.ApplicationPath + appPath; } string bootUrl = HttpContext.Current.Request.Url.Scheme + "://" + HttpContext.Current.Request.Url.Authority; if (!string.IsNullOrEmpty(pUrl) && pUrl.Substring(0, 1) == "/") { pUrl = pUrl.Substring(1); } string fullUrl = bootUrl + appPath + pUrl; return fullUrl; } 哦,这个不需要. 只要一边调用的引用了就行了` 如果一边更改了WebService 代码 编译后另一半重新更新下WebService即可. 你只要知道,A调用B是需要写方法,那B调用A还不是要写方法的 不用两面都写webservice吧,一边写另一边调用就行了,无非就是发数据和接数据两种操作呗。 dateTime在数据库格式化问题 高手们,我想问个关于套接字的问题 代码完全正确,怎么会出现找不到服务器? 关于变量定义 MS的SqlHelper可以用SqlTransaction么?
