= CSharp =
CSharp is a multi-paradigm programming language encompassing strong typing, imperative, declarative, functional, procedural, generic, object-oriented (class-based), and component-oriented programming disciplines. It was developed by Microsoft within its .NET initiative and later approved as a standard by Ecma (ECMA-334) and ISO (ISO/IEC 23270:2006). C# is one of the programming languages designed for the Common Language Infrastructure. From [[http://en.wikipedia.org/wiki/C_Sharp_(programming_language)|Wikipedia]]

== Compile code based on csc (CSharp compiler) ==
Look for the compiler in '''c:\windows\Microsoft.NET\Framework\<version>\csc.exe'''

Hello world sample code:
{{{#!highlight csharp
using System;

namespace org.bitarus.allowed
{
  public class Program
  {
    public static void Main(string[] args)
    {
      System.Console.WriteLine("Hello world");
    }
  }
}

}}}

Compile HelloWorld.cs:
 * csc /t:exe /out:HelloWorld.exe HelloWorld.cs

== Build batch file example .NET 4.0 ==
{{{
C:\Windows\Microsoft.NET\Framework\v4.0.30319\csc.exe /t:library /out:libx.dll src\_Default.cs src\DALSql.cs src\Global.cs
}}}

== app.config sample ==
{{{#!highlight xml
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <appSettings>
    <add key="keyx" value="valuex"/>
  </appSettings>
</configuration>
}}}

{{{#!highlight csharp
using System.Configuration;
//.....
string valuex = ConfigurationManager.AppSettings["keyx"];
System.Console.WriteLine(valuex);
}}}


Copy src/app.config to AppX.exe.config.

== JSON library several :net version ==

=== Deserialization example ===
{{{#!highlight csharp
// mcs test.cs /r:Newtonsoft.Json.dll  
// mono test.exe 

using Newtonsoft.Json;
using System;

public class Reply{
  public int mnr {get;set;}
  public int fnr {get;set;}
  public MSG[] msg {get;set;}
}

public class MSG{
  public DateX date {get;set;}
  public string msg {get;set;}

}

public class DateX{
  [JsonProperty("$date")]
  public long datex { get;set; }  
}

public class Program{
  public static void Main(string[] args){
    string json = @"{\"mnr\": 1, \"fnr\": 777, \"msg\": [
{\"date\": {\"$date\": 1388679281000}, \"msg\": \"AAAAA\"}, 
{\"date\": {\"$date\": 1388678779000}, \"msg\": \"BBBBB\"}, 
{\"date\": {\"$date\": 1388676003000}, \"msg\": \"CCCCC\"}
]}";

    Reply r = JsonConvert.DeserializeObject<Reply>(json);
    System.Console.WriteLine(String.Format("Fnumber:{0} MNumber:{1}",r.fnr,r.mnr));

    foreach(MSG msg in r.msg) {
      System.Console.WriteLine(String.Format("MSG:{0} Date:{1} ",msg.msg, msg.date.datex ));
    }      
  }
}
}}}
