c# - Passing complex type to windows service with WCF -


I have a Windows service and winoff front end app, in order to call and pass data roundtrip for services I need to be enabled. I have completed it by defining an interface and can overcome the string without any problems. 

  [ServiceContract] Public Interface Rating Ruler [[DataContract Formatted] [OperationContract] String Reverse String (String Value); }   
 Now I am trying to return a complex data type and changed the code like this:  
  [ServiceContract] public Interface IStringReverser {[DataContractFormat] [Operation Contract] DTO reverse string (string value); } [Serialable] public class dto {public id id}; Set; } Public string name {get; Set; }}   
 My implementation is as follows:  
  public class string reverser: optimizing reverser {public DTO reverse string (string value) {char [] retVal = value ToCharArray (); int idx = 0; For (int i = value.Length - 1; i> = 0; i--) Rated [idx ++] = value [i]; Var DTO = new DTO (); Dto.Name = retVal.ToString (); Dto.Id = 122; Return DTO; }}   
 I do not transfer data specifically: I get an error:  
 
 While trying to deserialize the message, the formatter has an exception Throwed: There was an error while trying to deserialize the parameter. Innerexception message '' andaalation '' reverse string result 'is not expected' from namespace. Expected element '_x003C_Id_x003E_k__ backingfield'. Please see InnerException for more information.   
 I am making a connection with this in Winform:  
  Private IStringReverser pipeProxy; Public Form 1 () {Initialization (); ChannelFactory & LT; IStringReverser & gt; HttpFactory = New Channel Factoring & lt; IStringReverser & gt; (New basic httbadding (), new endpoint address ("http: // localhost: 8000 / reverse"); ChannelFactory & LT; IStringReverser & gt; Pipfactor = New Channel Factor & lt; IStringReverser & gt; (New NetNamedPipeBinding (), new EndpointEditor ("netpoep: // localhost / pipe rails")); // Istring Reporter httpProxy = httpFactory.CreateChannel (); Pipiproxy = pipefrenchure.createchannel (); }   
 I do not understand the error message or how to correct it. How do I define how to get it deserialized? Is the serialization okay?   
 
 
 Use Data Contracts:  
  [DataContract] DTO {[Database] Public Entry ID (Receive); Set; } [Datamember] public string name {get; Set; }}

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise. To clarify - this will not be a method error because it is a linked list. There should not be any way involved. import java.awt. *; Import java.awt.event. *; Import javax.swing. *; Import java.util. *; Import java.util.Scanner; Import java.util.LinkedList; Public class TopTenList JFrame {Private TopTenList tt; See the Private JTextArea list; Private JTextField cmdTextField; Private JTextField resultsTestfield; // This GUI window is the code for the public toptist...

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
