我试图将一个值(从一个对象)放入一个变量中,并将其放入一个表单的文本框中。
以下是表单代码:
public Form1(Deck mainDeck)
{
InitializeComponent();
int Val = mainDeck.ReturnCard(10);
textBox1.Text = Val.ToString();
}
maindeck是program.cs文件中的一个对象
问题是这个行:int val=maindeck.returncard(10);
哦,错了。
这是真的:
Error 1 The name 'mainDeck' does not exist in the current context C:\Users\Chris\Documents\Visual Studio 2008\Projects\Pcard\Pcard\Form1.cs 17 23 Pcard
这是我的program.cs文件:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Windows.Forms;
namespace Pcard
{
class Deck
{
public Deck()
{
// Assign standard deck to new deck object
// int j;
for (int i = 0; i != currentDeck.Length; i++)
{
currentDeck[i] = originalCards[i];
}
// Fisher-Yates Shuffling Algorithim --- Do initial shuffle
Random rnd = new Random();
for (int k = currentDeck.Length - 1; k >= 0; k--)
{
int r = rnd.Next(0, k + 1);
int tmp = currentDeck[k];
currentDeck[k] = currentDeck[r];
currentDeck[r] = tmp;
}
}
public void Shuffle()
{
Random rnd = new Random();
for (int k = currentDeck.Length - 1; k >= 0; k--)
{
int r = rnd.Next(0, k + 1);
int tmp = currentDeck[k];
currentDeck[k] = currentDeck[r];
currentDeck[r] = tmp;
}
}
public int[] ReturnDeck()
{
return currentDeck;
}
public int ReturnCard(int num)
{
return currentDeck[num];
}
public int[] originalCards = new int[54]
{
0x11, 0x12, 0x13, 0x14, 0x15, 0x16, 0x17, 0x18, 0x19, 0x1A, 0x1B, 0x1C, 0x1D,
0x21, 0x22, 0x23, 0x24, 0x25, 0x26, 0x27, 0x28, 0x29, 0x2A, 0x2B, 0x2C, 0x2D,
0x31, 0x32, 0x33, 0x34, 0x35, 0x36, 0x37, 0x38, 0x39, 0x3A, 0x3B, 0x3C, 0x3D,
0x41, 0x42, 0x43, 0x44, 0x45, 0x46, 0x47, 0x48, 0x49, 0x4A, 0x4B, 0x4C, 0x4D,
0x50, 0x51
};
private int[] currentDeck = new int[54];
}
public class Program
{
static void Main(string[] args)
{
// Create a Deck object
Deck mainDeck = new Deck();
Console.WriteLine("Here is the card array:");
for (int index = 0; index != 54; index++)
{
string card = mainDeck.ReturnCard(index).ToString("x");
Console.WriteLine("0x" + card);
}
//Return 10th Card
int PickCard = mainDeck.ReturnCard(10);
Console.WriteLine("Here is the 10th Card");
Console.WriteLine("0x" + PickCard);
//Shuffle
mainDeck.Shuffle();
Console.WriteLine("Shuffling..");
PickCard = mainDeck.ReturnCard(10);
Console.WriteLine("Here is the 10th card now: 0x" + PickCard);
Application.Run(new Form1(maindeck));
}
}
}
编辑:好的,我正在将主甲板传递到表单,但现在出现了一个不同的错误:
Error 1 Inconsistent accessibility: parameter type 'Pcard.Deck' is less accessible than method 'Pcard.Form1.Form1(Pcard.Deck)' C:\Users\Chris\Documents\Visual Studio 2008\Projects\Pcard\Pcard\Form1.cs 14 16 Pcard
编辑:好的,我现在有这个工作,但是我遇到了一个相关的问题,所以我宁愿把它放在这里,而不是放在一个新的问题上。
将maindeck传递给form1很好,但是如果我想让一个按钮点击调用这个对象中的一个方法呢?我试着这样经过主甲板:
private void button1_Click(object sender, Deck mainDeck, EventArgs e)
{
mainDeck.Shuffle();
}
我得到这个错误:
Error 1 No overload for 'button1_Click' matches delegate 'System.EventHandler' C:\Users\Chris\Documents\Visual Studio 2008\Projects\Pcard\Pcard\Form1.Designer.cs 51 35 Pcard
加油!
最佳答案
线路
甲板主甲板=新甲板();
只需创建一个名为maindeck的局部变量…只能在main()方法中访问…
将声明放在类中main方法的上方…将程序类和主甲板作为公共静态…这样地
public class Program
{
// Create a Deck object
public static Deck mainDeck = new Deck();
static void Main(string[] args)
{
.....
}
然后您可以从您的表单访问
int Val = Program.mainDeck.ReturnCard(10);
希望这有帮助。
