error C2059: syntax error : 'public',该怎么解决

error C2059: syntax error : 'public'
我使用VS2010 Pro。

我添加web引用到VC项目，使用/CLR建立时，报错：

error C2059: syntax error : 'public'd:\visual studio 2008

\projects\myproject\myproject\Service1.h29MyProject

错误指向代码：

  [System::CodeDom::Compiler::GeneratedCodeAttribute(L"wsdl", 

L"2.0.50727.1432")]
public delegate System::Void HelloWorldCompletedEventHandler

(System::Object^ sender, Service1::HelloWorldCompletedEventArgs^ e);

Service1.h是我添加web引用后自动生成的。


[解决办法]
public delegate System::Void HelloWorldCompletedEventHandler
是否应该为
public delegate Void System::HelloWorldCompletedEventHandler

[解决办法]
c++哪来的public void somemethod(){} 定义

c++ 应该 
ref class{
public: 
void method(){}
}
[解决办法]
我这里没有2010 
2005生成的是

C/C++ code

 public ref class Service : public System::Web::Services::Protocols::SoapHttpClientProtocol {                private: System::Threading::SendOrPostCallback^  HelloWorldOperationCompleted;                /// <remarks/>        public: event localhost::HelloWorldCompletedEventHandler^  HelloWorldCompleted;                /// <remarks/>        public: Service();        /// <remarks/>        public: [System::Web::Services::Protocols::SoapDocumentMethodAttribute(L"http://tempuri.org/HelloWorld", RequestNamespace=L"http://tempuri.org/",             ResponseNamespace=L"http://tempuri.org/", Use=System::Web::Services::Description::SoapBindingUse::Literal, ParameterStyle=System::Web::Services::Protocols::SoapParameterStyle::Wrapped)]        System::String^  HelloWorld();                /// <remarks/>        public: System::IAsyncResult^  BeginHelloWorld(System::AsyncCallback^  callback, System::Object^  asyncState);                /// <remarks/>        public: System::String^  EndHelloWorld(System::IAsyncResult^  asyncResult);                /// <remarks/>
