發布時間：2024/10/8 C# 104 豆豆

生活随笔收集整理的這篇文章主要介紹了 C#开发XML WebService接口(SOAP) 小編覺得挺不錯的,現在分享給大家,幫大家做個參考.

????????????//1)用XML閱讀器從一個文件路徑或者是網絡路徑中讀入WSDL文件：???
????????????XmlTextReader?reader?=?new?XmlTextReader(v_WSDL);//加入?using?System.Xml;???
????????????//2〉把讀到的內容用ServiceDescription來描述：???
????????????ServiceDescription?sd?=?ServiceDescription.Read(reader);???//加入using?System.Web.Services.Description;???
????????????//3）用服務導入器把得到的描述導入服務描述中：???
????????????ServiceDescriptionImporter?sdi?=?new?ServiceDescriptionImporter();???
????????????sdi.AddServiceDescription(sd,null,null);???
????????????//4）指定要動態編譯的代碼的命名空間：???
????????????CodeNamespace?cn?=?new?CodeNamespace(v_NameSpace);???//"DynamicServices"
????????????//5）指定要動態編譯的代碼單元：???
????????????CodeCompileUnit?ccu?=?new?CodeCompileUnit();???
????????????//6）把命名空間添加到動態編譯的代碼單元的命名空間組中去：???
????????????ccu.Namespaces.Add(cn);???
????????????//7）指示服務導入器把該動態編譯單元內該命名空間的代碼導進去，作為新的動態服務描述：???
????????????sdi.Import(cn,ccu);???
????????????//8）新建一個C#編譯器來編譯：???
????????????ICodeCompiler?icc?=?new?Microsoft.CSharp.CSharpCodeProvider().CreateCompiler();??
????????????//9)新建一個編譯參數對象（在這里我們設置它為空的編譯參數）：???
????????????CompilerParameters?cp=new?CompilerParameters();????
????????????//10)指示C#編譯器，按照?CP?編譯參數對象提供的參數來進行?CCU?單元的編譯。并把編譯結果傳給?編譯結果對象?cr：???
????????????CompilerResults?cr?=?icc.CompileAssemblyFromDom(cp,?ccu);???
????????????//11）從動態編譯結果中獲取?某個?字符串（通常是該類型名字）所表示的真實類：???
????????????Type?t?=?cr.CompiledAssembly.GetType(v_ClassName);???//其中的DynamicServices必須和CodeNamespace?cn?=?new???CodeNamespace("DynamicServices");定義的同名??
????????????//12）創建該類的實例：???
????????????Object?obj?=?Activator.CreateInstance(t);???????????
????????????//13）根據方法名稱字符串?反射到該方法的實體：???
????????????System.Reflection.MethodInfo?mi?=?obj.GetType().GetMethod(v_WebMethod);??????????????
????????????//14）用該方法實體的.Invoke()來調用該方法：???
????????????string?ret?=?System.Convert.ToString(mi.Invoke(obj,?v_args));??//,new?object[]{"傳給方法的參數1","傳給方法的參數2"}));????
????????????return?ret;
????????????
????????????//????????????添加Web?引用，在WSDL一欄中把剛才得到的WSDL地址復制過來，Web?引用的名稱輸入JavaService
????????????//????????????JavaService.ServiceService?bean?=?new?JavaService.ServiceService();
????????????//????????????string?aa?=?bean.IfService("ifUser","ifPass","ifCode","ifEvent","info");
