You appear to have defined Customer twice. Once in each service. You should place Customer in its own Class Library project and then reference it from any other project that needs it. Assuming Customer is identical in each of the existing projects this should work fairly easily. However, if Customer in each of the existing projects, is the same in name only then you have a lot of work ahead of you to redesign your application.

The Customer Object is in a separate class library project only. I have referenced it in both the services. Now my win application is consuming both the service. Now i am getting the Customer object as an output of Service1 that has a datatype of Service1.Customer and when i try to pass it as an input to one of the methods in Service two that expects Service2.Customer, I am not able to do it.
The contents of the object Customer are the same.
Now what to do?

I'm confused. You now appear to have 3 definitions for a Customer object. You should only have one throughout your entire solution.

You should be using only the customer object in the class library. You need to remove the definitions of Customer in the Services and use the Customer class in the class library instead. You can add the class library as a reference to each project that needs it. You can do that by right-clicking the project and selecting "Add Reference..." and going to the projects tab and choosing the class library project that contains the Customer class.

Hey i am doing as you are telling only. There are no multiple copies of the class. It is there in the common project(separate class library). But when you use the class by adding reference to the services then the wsdl of each and every service since it is in a different namespace will consider the same class as two different class files.

Calling a function without an object

Hi..

I m developing a C# compiler for which i have a utility package.
That package has lots of funtions.
i want to call those functions without an object. and i don't want
those functions to be static.

how can i achieve this..

plz help me.

regards,
nas

why you want to cancel the (static) option ??

becaus i want to call the function directly

as:-
.....
func1();
.....

and not as:-
.....
className.func1();
.....

as we cal function in C..

Tamimi - Code8-Apr-07 23:34

8-Apr-07 23:34

maybe iam wrong, but i don't think that is possible.
if you wrote a function on a class A and you want to access it
from another class B then you cannot access it regardless class A.

anyway thanx for reply..

i hav another doubt..

i want to include a file, similarly as of #include.
only i want to copy the code at the position where i call the function IncludeFile().

could you be more specific, i didn't understand the new question..

this is not a professional way to do it , suppose you that you will
use that code again, what will happen ?? you will copy the code again ??

Actually, we are developing an application to test the User Load for any Website..

below is the script of our tool that loads virtual user and tests the site..

using System;
using RTGWebLoad;

namespace Coolgoose   
{
  public class Transaction
  {
    private string username;
    private string password;
        
    public void TransactionMain(RTGHttpBrowser wlHttp, string ThreadNum, long RoundNum, long MaxRounds)
    {
      wlHttp.BeginTransaction("Coolgoose_SendingMail");
      CallCoolGooseSendMail(wlHttp, ThreadNum, RoundNum, MaxRounds);
      wlHttp.EndTransaction("Coolgoose_SendingMail");
    }
    
    public void CallCoolGooseSendMail(RTGHttpBrowser wlHttp, string ThreadNum, long RoundNum, long MaxRounds)
    {
      if (RoundNum == 1)
        CGLogin(wlHttp);

      CGSM(wlHttp);

      //if (RoundNum % MaxRounds == 0)
      //  CGLogout(wlHttp);      
    }

    public void CGLogin(RTGHttpBrowser wlHttp)
    {      
      string[] loginData = wlHttp.GetData("http://10.80.4.43/?get=userpass", ',');
      username = loginData[0];
      password = loginData[1];
      
      //username = "rtguser";
      //password = "rtguser";
     
      wlHttp.Get("http://www.cooltoad.com");
      //wlHttp.CheckString("RTGian");
      
      wlHttp.InfoMessage("Page1: " + wlHttp.wlSource);
            
      wlHttp.Get("http://www.cooltoad.com/go/email");
      wlHttp.Get("http://www.cooltoad.com/account/login.php?mail=1");

      wlHttp.ContentType = "application/x-www-form-urlencoded";

      wlHttp.FormData("ACCOUNT", username);
      wlHttp.FormData("PASSWORD", password);      
      
      wlHttp.Post("http://www.cooltoad.com/account/login.php?mail=1");

      //bool bFlag = wlHttp.CheckString("This site uses frames");    // check string
      //wlHttp.InfoMessage(bFlag.ToString());      

      wlHttp.Get("http://www.cooltoad.com/common/header_email.php");
      wlHttp.Get("http://as03.cooltoad.com/go/desktop?p=folders");
      wlHttp.Get("http://as03.cooltoad.com/go/desktop?o=folder:inbox");
      wlHttp.InfoMessage("------" + username + " logged IN ------");
      //wlHttp.ErrorMessage("Error in Agenda");
    }

    public void CGSM(RTGHttpBrowser wlHttp)
    {      
      wlHttp.Get("http://as03.cooltoad.com/go/desktop?c=new");

      string sCompose = wlHttp.FindString(wlHttp.wlSource, "COMPOSE\" VALUE=\"", "\">");            
      
      wlHttp.ContentType = "multipart/form-data";
      wlHttp.FormData("TO", "xyz@gmail.com");
      wlHttp.FormData("CC", "");
      wlHttp.FormData("SUBJECT", "Testing LTT -- Naveed");
      wlHttp.FormData("ATTACHMENT_DATA.wlFile-Name", "");
      wlHttp.FormData("ATTACHMENT_DATA.wlContent-Type", "application/octet-stream");      
      wlHttp.FormData("MESSAGE", "Testing LoadTestingTool");
      wlHttp.FormData("TZO", "-330");
      wlHttp.FormData("C:SEND:::NEW.x", "12");
      wlHttp.FormData("C:SEND:::NEW.y", "9");
      wlHttp.FormData("COMPOSE", sCompose);     // parameterization
      wlHttp.Post("http://as03.cooltoad.com/go/desktop");
      //wlHttp.CheckString("Need more space");    // check string
      wlHttp.InfoMessage("Compose: " + sCompose + " --- " + username);
    }

    public void CGLogout(RTGHttpBrowser wlHttp)
    {
      wlHttp.Get("http://as03.cooltoad.com/go/desktop?c=logout");
      wlHttp.ClearCookies();
      wlHttp.InfoMessage("------" + username + " logged OUT ------");
    }
  }
}

after writing this script we wil pass this to our Testing tool, which compiles this C# script and starts the run.
we want to tune our code, so that we can write this script in more better way..

currently the InfoMessage() functions are in the same package RTGWebLoad..
we want to move it to another package and can be called without an object or class name..

one of my mate suggest me to include the package's code as we do in C (using #include).

nas

Your mate is thinking the wrong way for C#.

You can wrap this code in to a class library of its own. Then you can reference the class library from where it is needed, if it is needed in multiple projects.

Using can be used in two places. In the context of this conversation you mean the way using is used as a directive to import namespaces into the current code file.

Using allows the developer to call the class name on its own rather than be forced to use its full name. e.g.

using System.Data.SqlClient;
...
SqlConnection connection = new SqlConnection();

System.Data.SqlClient.SqlConnection = new System.Data.SqlClient.SqlConnection();

C# has no need of that funtionality.

If you want to be able to use classes, structs, etc. from other namespaces without having to refer to it fully each time use add the appropriate using directive at the top of the class file.

You may also have to add a reference to the appropriate assembly that contains the code. To do this, right-click on the project you wish to add the reference to and select "Add Reference...". The dialog contains various tabs that indicate where the assemby is.
