动态webservice和静态webservice效率巨大差距

由于公司项目需要研究webservice 由来已久,webservice的效率问题一直是个让人头疼的事情.

N就前,鄙人研究了动态反射形式的动态形webservice,也大规模应用在了项目里,怎奈效率却低下到一定程度.

具体代码鄙人也贴出来,也就是网上流行的那个动态调用方法

        ///<summary>
        ///动态Web服务代理方法
        ///</summary>
        ///<param name="@namespace">传入空间命名</param>
        ///<param name="url">传入URL参数</param>
        ///<param name="classname">传入类名</param>
        ///<param name="methodname">传入方法名</param>
        ///<param name="args">传入参数，本参数为顺序参数</param>
        public object InvokeWebservice(string url,string @namespace,string classname,string methodname,object[] args)
        {
            try
            {
                System.Net.WebClient wc = new System.Net.WebClient();
                System.IO.Stream stream = wc.OpenRead(url + "?WSDL");
                System.Web.Services.Description.ServiceDescription sd = System.Web.Services.Description.ServiceDescription.Read(stream);
                System.Web.Services.Description.ServiceDescriptionImporter sdi = new System.Web.Services.Description.ServiceDescriptionImporter();
                sdi.AddServiceDescription(sd,"","");
                System.CodeDom.CodeNamespace cn = new System.CodeDom.CodeNamespace(@namespace);
                System.CodeDom.CodeCompileUnit ccu = new System.CodeDom.CodeCompileUnit();
                ccu.Namespaces.Add(cn);
                sdi.Import(cn,ccu);

                Microsoft.CSharp.CSharpCodeProvider csc = new Microsoft.CSharp.CSharpCodeProvider();
                System.CodeDom.Compiler.ICodeCompiler icc = csc.CreateCompiler();

                System.CodeDom.Compiler.CompilerParameters cplist = new System.CodeDom.Compiler.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");

                System.CodeDom.Compiler.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());
                }
                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));
            }
        }

动态是被我动态上了,可惜效率却太不行了,今天实在感觉到不行了,就测试了静态.

不测不知道,一测试吓一跳.

动态方法

用了 1.29秒才加载完毕

然后我直接用静态测试后

只用了0.43秒

差距实在太大了.

不知道各位有没有动态调用的方法,最起码要实现URL是动态的.

如有知道麻烦告之,谢谢!
