Why there is an error in p.t(); and string o = p.h();
"Error CS0236 A field initializer cannot reference the non-static field, method, or property 'FirstNameController.p' assign_5 "
You need move your code to a method in class, also make class Person as public to accessable from another namespace as
public class Person{}
class FirstNameController
{
void test(){
Person p = new Person();
p.t();
string o = p.h();
}
}

My brain is broken. The program is setup to ask the user for an address. A simple console question that puts the users input into a string. Then I wish to pass the variable to a reference class library to put the string into a QRcode "barcode".
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using QRmaker;
namespace AddressInq
{
class Program
{
public class getInput
{
public static string input { get; set; }
}
static void Main(string[] args)
{
Console.WriteLine("Please enter the address: ");
string input = Console.ReadLine();
}
}
}
The QR code:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Drawing;
using QRCoder;
namespace QRmaker
{
class program
{
public void codeMake()
{
QRCodeGenerator generator = new QRCodeGenerator();
QRCodeData qrCodeData = generator.CreateQrCode(input, QRCodeGenerator.ECCLevel.Q);
QRCode qrCode = new QRCode(qrCodeData);
Bitmap qrCodeImage = qrCode.GetGraphic(20);
qrCodeImage.Save("Address.bmp");
}
}
}
Try this:
In QRMaker:
namespace QRmaker
{
class Program
{
public static void codeMake(string input)
{
var generator = new QRCodeGenerator();
var qrCodeData = generator.CreateQrCode(input, QRCodeGenerator.ECCLevel.Q);
var qrCode = new QRCode(qrCodeData);
var qrCodeImage = qrCode.GetGraphic(20);
qrCodeImage.Save("Address.bmp");
}
}
}
In AddressInq:
namespace AddressInq
{
class Program
{
static void Main(string[] args)
{
Console.WriteLine("Please enter the address: ");
QRmaker.Program.codeMake(Console.ReadLine());
}
}
}
What I did was to convert the codeMake method to static so that you do not have to instantiate the Program class to access it ...
You have to call the Program class that is in the QRmaker namespace including the namespace before the name of the class: Namespace.Class.Method.
My code for Form

My class for generating random number for all the dice.
This works perfectly fine.

{
int intDice_1 = rnd.Next(1, 7);
return intDice_1;
}
public int intDice_2_Roll()
{
int intDice_2 = rnd.Next(1, 7);
return intDice_2;
}
public int intDice_3_Roll()
{
int intDice_3 = rnd.Next(1, 7);
return intDice_3;
}
public int intDice_4_Roll()
{
int intDice_4 = rnd.Next(1, 7);
return intDice_4;
}
public int intDice_5_Roll()
{
int intDice_5 = rnd.Next(1, 7);
return intDice_5;
}
}
}
Class to change button background image.
This is where my problem is, the code works if I put it on my form but it does nothing when I make it a method on another class.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using YAHTZEE.Properties;
namespace YAHTZEE
{
class Class1 : GameMainWindow
{
public void buttonDice_1Manager()
{
DiceManager dm = new DiceManager();
if (dm.intDice_1_Roll() == 1)
{
buttonDice_1.BackgroundImage = Properties.Resources.Dice1;
}
}
}
}
Am I missing something?
P.S. I want them to be separated because there are a lot of things to consider making my code very long.
In class1, try changing your method to:
public System.Drawing.Bitmap dice1Manager(int diceRoll)
{
if(diceRoll == 1)
return Properties.Resources.Dice1;
}
In your main class, change what you have to:
private void buttonRollDice_Click(object sender, EventArgs e)
{
DiceManager dm = new DiceManager();
Class1 c1 = new Class1();
button_dice1.BackgroundImage = c1.dice1Manager(dm.intDice_1_Roll());
dm.intDice_2_Roll();
dm.intDice_3_Roll();
dm.intDice_4_Roll();
dm.intDice_5_Roll();
}

A class named Round is a level design in a adventure game.Its filed number indicate which level the player is in. Different level will have different figures to guess. The figures are produced by field FigureFactory.
The question is: using Ninject for dependency injection, how can I set the cooresponding FigureFactory to the variable round, according to the field number? For instance, when field number==1, the cooresponding factory is FigureFactory1, when field number==2, the cooresponding factory is FigureFactory2?
using GuessFigure.Model.Factory;
using Ninject;
using Ninject.Modules;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Ninject.Planning.Bindings;
namespace GuessFigure.Model
{
class Round
{
private int number=1;
private FigureFactory figureFactory;
[Inject]
internal void SetFigureFactory(FigureFactory figureFactory)
{
this.figureFactory = figureFactory;
}
public int[] GetCurrentRoundFigures()
{
return figureFactory.Produce(number);
}
}
//this not work, help please
class RoundModule : NinjectModule
{
public override void Load()
{
Bind<FigureFactory>().To<FigureFactoryRound1>().When(request=>request.ParentRequest.Target.Type.GetField("number").Equals(1));
Bind<FigureFactory>().To<FigureFactoryRound2>().When(request => request.Target.Type.GetField("number").Equals(2));
Bind<FigureFactory>().To<FigureFactoryRound3>().When(request => request.Target.Type.GetField("number").Equals(3));
Bind<FigureFactory>().To<FigureFactoryRound4>().When(request => request.Target.Type.GetField("number").Equals(4));
Bind<FigureFactory>().To<FigureFactoryRound5>().When(request => request.Target.Type.GetField("number").Equals(5));
}
}
}
Factory Method Pattern implementation:
using System;
namespace GuessFigure.Model
{
abstract class FigureFactory
{
protected int figureNumber;
public FigureFactory(int figureNumber)
{
this.figureNumber = figureNumber;
}
internal int[] Produce()
{
int[] figureArray = new int[figureNumber];
for (int i = 0; i < figureNumber; i++)
{
figureArray[i] = Algorithm(i + 1);
}
return figureArray;
}
abstract protected int Algorithm(int inputNumber);
}
}
Concrete Factory（there are still some like this）；
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace GuessFigure.Model
{
class FigureFactoryRound1 : FigureFactory
{
public FigureFactoryRound1(int figureNumber) : base(figureNumber)
{
}
protected override int Algorithm(int inputNumber)
{
return inputNumber;
}
}
}
class FigureFactoryRound3 :
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace GuessFigure.Model.Factory
{
class FigureFactoryRound3 : FigureFactory
{
public FigureFactoryRound3(int figureNumber) : base(figureNumber)
{
}
protected override int Algorithm(int inputNumber)
{
return (int) Math.Pow( inputNumber,2) ;
}
}
}
class FigureFactoryRound4 :
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace GuessFigure.Model.Factory
{
class FigureFactoryRound4 : FigureFactory
{
public FigureFactoryRound4(int figureNumber) : base(figureNumber)
{
}
protected override int Algorithm(int inputNumber)
{
return (int)Math.Pow(inputNumber, 3);
}
}
}
Usage:
IKernel kernel = new StandardKernel(new RoundModule());
Round round = new Model.Round();
round.SetFigureFactory(kernel.Get<FigureFactory>());
int[] array=round.GetCurrentRoundFigures();
I am trying to read JSON data from web, and i am using Json.net library for this task, the problem is if there is only one json object
{"id":"2340","time":"2014-10-29 16:26:49"}
everything works fine, but if there is an array of them
[{"id":"2340","time":"2014-10-29 16:26:49"}, {"id":"2341","time":"2014-10-29 16:27:21"}]

I've tried to add
public class DataContainer
{
public List<LocalhostTiming> LocalhostTiming{ get; set; }
}
But i dont know how to work with this code.
You are trying to deserialize an array of LocalhostTiming into one instance of it.
You need to deserialize the object to an array.
List<LocalhostTiming> jsonResponse = JsonConvert.DeserializeObject<List<LocalhostTiming>>(htmlCode);
