oop - Designing classes in C# -

-

I know this should be a general question, but take a look:

I have a The test is class: 

  public class EmployeeClass {Private Int _id; Private string _name; Private double _ salaris; Public Entry ID {{}} {{}} set {...}} public string name {get} {{}} set {...}} // and so on} {/ code>  
 The question is: For me, it is not able to understand the public properties that match all the private areas.  
 What is the approach to limiting access to the class intents?  
 At the time of initialization, I reach the field directly, like:  
  public employee class (int id, string name, double pay) {_id = id; _name = name; _salary = Pay; }  
 
 And do everything (at least those who have some kind of irreversibleness) read only? 
 
 What's the best way here? 
 
 Thank you for your opinion

There are several approaches, two of them in class In general, (and this is only a small taste):

    • On many public-setters classes

    asp.net - Javascript/DOM Why is does my form not support submit()? -

    -
    This is my first time working with asp.net and javascript, so I do not know very good web resources, or Much about javascript debugging I have to find out that on line oFormObject.submit (); Microsoft JScript Runtime Error: Object does not support this property or method I am using the link to work as a button because I am terrible in aesthetics and I think That link will look more professional than a table of 50 buttons. I have read that this solution can cause problems with browsers due to pre-rendering of my links and many additional traffic and problems, but CSS gives me a button like a link, which has issues of alignment and difference seemed to. & lt ;!

    -
    I am trying to implement one for Delphi, but there are some problems with communication. Fitnesse will start my process, and give me a portmember as a command line argument. Then I should make a socket on the port number given to me, and fitness will connect to that port I am using a TCPCP server for the job: < Pre> TcpServer1.LocalPort: = ParamStr (ParamCount); TcpServer1 Active: = true; On OnEXEPT () -Event, I send the protocol version to use as specified in the protocol.

Syndrome ('slim - v 0.0', # 10); SetLength (S, 6); ClientSketts Receavebook (S, 6); End; When I call ReceiveBuf (), the process ends, and fitness throws an exception: java.net.SocketException: connection Reset I have seen what sent and received.

    -
    I have a strange problem that I really do not know. In addition to developing a new ASP.NET site, I have to support the old "classic ASP" site. It is written in VBScript with a batch of JavaScript functions. Many of the JavaScript functions include 'files' Everything is fine on our production system (which security is controlled by another group - this is a military installation) Debugging them once did not work I). However, I have a fix for a vague bug that needs to be fully tested and some functions do not run under the "local" copy of the website that runs on my PC. For the record, I am running IIS 5.1 on XP. The problem is that some Javascript functions are running "OK" on the production server, but when they use it as a server, they are not defined on my PC what is happening that last Programmer, for some reason, has decided to put some functions in a series of files, which according to the observations, imitate the "need_once
