Silverlight动态调用WEBSERVICE,WCF方法
此方法只要知道SERVICE地址与要执行的方法名与参数即可调用webservice,
注意这个只是在普通工程中才可用。silverlight调用方法请往后看:

- public static object InvokeWebService(string url, string classname, string methodname, object[] args)
- {
- object obj = GetWebServiceClassObject(url,classname);
- Type t = obj.GetType();
- System.Reflection.MethodInfo mi = t.GetMethod(methodname);//通过反射获得方法名
- return mi.Invoke(obj, args);//使用制定的参数调用当前实例所表示的方法,执行方法
- }
- /// <summary>

- public static object GetWebServiceClassObject(string url, string classname)
- {
- string @namespace = "ServiceBase.WebService.DynamicWebLoad";
- if (classname == null || classname == "")
- {
- classname = GetClassName(url);
- }
- ///动态调用类所执行的过程
- //1.获取服务描述语言(WSDL)
- WebClient wc = new WebClient();
- Stream stream = wc.OpenRead(url + "?WSDL");
- ServiceDescription sd = ServiceDescription.Read(stream);//设置Web服务描述语言
- ServiceDescriptionImporter sdi = new ServiceDescriptionImporter();//生成客户端代理类
- sdi.AddServiceDescription(sd, "", "");
- CodeNamespace cn = new CodeNamespace(@namespace);//声明命名空间
- //2.生成客户端代理类代码
- CodeCompileUnit ccu = new CodeCompileUnit();//为CodeDOM程序图形提供容器
- ccu.Namespaces.Add(cn);//获取命名空间集合
- sdi.Import(cn, ccu);
- CSharpCodeProvider csc = new CSharpCodeProvider();//提供对 C# 代码生成器和代码编译器的实例的访问
- //ICodeCompiler icc = csc.CreateCompiler();//定义用于调用源代码编译的接口或使用指定编译器的 CodeDOM 树
- //3.设定编译器的参数
- CompilerParameters cplist = new CompilerParameters();
- cplist.GenerateExecutable = false;//设置是否为可执行文件
- cplist.GenerateInMemory = true;//设置是否在内存中生成输出
- cplist.ReferencedAssemblies.Add("System.dll");
- cplist.ReferencedAssemblies.Add("System.XML.dll");
- cplist.ReferencedAssemblies.Add("System.Web.Services.dll");
- cplist.ReferencedAssemblies.Add("System.Data.dll");
- //4.编译代理类
- CompilerResults cr = csc.CompileAssemblyFromDom(cplist, ccu);// icc.CompileAssemblyFromDom(cplist, ccu);//使用指定的编译器设置编译程序集
- if (true == cr.Errors.HasErrors)
- {
- System.Text.StringBuilder sb = new StringBuilder();
- foreach (CompilerError ce in cr.Errors)
- {
- sb.Append(ce.ToString());
- sb.Append(System.Environment.NewLine);
- }
- throw new Exception(sb.ToString());
- }
- //5.生成代理实例,并调用方法
- System.Reflection.Assembly assembly = cr.CompiledAssembly;//获取或设置已编译的程序集
- Type t = assembly.GetType(@namespace + "." + classname, true, true);
- object obj = Activator.CreateInstance(t);//为 COM 对象提供对方法的版本无关的访问
- return obj;
- }
- private static string GetClassName(string url)
- {
- string[] parts = url.Split('/');
- string[] pps = parts[parts.Length - 1].Split('.');
- return pps[0];
- }
下面来看一下动态调用WCF服务:
这是我在一个项目中,为了不去配置服务地址,直接解析当前访问路径,加上服务的后面部分生成与SILVERLIGHT同一域名下的服务:
这个方法的前提是要先引用这个服务,这是silverlight下用的,普通程序中也差不多
折叠C# 代码
- /// <summary>
- /// 获取配置远程WCF服务对象
- /// </summary>
- public DMSTypeConfigWcfService.DMSTypeConfigServiceClient DmsTypeConfigWcfService
- {
- get
- {
- if (_DmsTypeConfigWcfService == null)
- {
- string url = Application.Current.Host.Source.Scheme + "://" + Application.Current.Host.Source.DnsSafeHost + ":" +
- Application.Current.Host.Source.Port + TypeConfigWcfUri; //这里就是获得当前URL再加上服务路径,当然你也可以配置在一个地方。
- EndpointAddress address = new EndpointAddress(url);
- BinaryMessageEncodingBindingElement binary = new BinaryMessageEncodingBindingElement();
- HttpTransportBindingElement transport = new HttpTransportBindingElement();
- CustomBinding binding = new CustomBinding(binary, transport);
- _DmsTypeConfigWcfService = new DMSTypeConfigWcfService.DMSTypeConfigServiceClient(binding, address);
- }
- return _DmsTypeConfigWcfService;
- }
- }
silverlight下调用webservice与WCF类似。主要是把CustomBinding 改为Http的一个binding
代码如下:FenbiSl.WimUpFile.UpFileServiceSoapClient就是引用进来的WEBSERVICE服务对象
url 是与silverlight在同一域名下.所以我这样就可以做到更换域名或部署时不需要重新改配置...
折叠C# 代码
- string url = Application.Current.Host.Source.Scheme + "://" + Application.Current.Host.Source.DnsSafeHost + ":" +
- Application.Current.Host.Source.Port + "/wim/UpFileService.asmx";
- EndpointAddress address = new EndpointAddress(url);
- BasicHttpBinding binding = new BasicHttpBinding(BasicHttpSecurityMode.None);
- UpFileClient = new FenbiSl.WimUpFile.UpFileServiceSoapClient(binding, address);
