我无法通过反射创建插件解决方案。当我单击一个 menuItem 时,我想在我的窗口中加载并显示另一个程序。我想我需要 3 个项目。
- 单击 menuItem 时想要加载另一个程序的客户端程序
- 我要加载的程序
- 插件类
代码客户端程序
private void nQueensToolStripMenuItem_Click(object sender, EventArgs e)
    {
        // Create an assembly object to load our classes
        string path = Application.StartupPath + "\\NQueens.dll";
        Assembly ass = Assembly.LoadFile(path);
        Type objType = ass.GetType("NQueens.NQueen");
        // Create an instace of NQueens.NQueen
        var instance = Activator.CreateInstance(objType);
        // public static bool berekenQueens()
        objType.InvokeMember("berekenQueens",
            BindingFlags.InvokeMethod | BindingFlags.Instance | BindingFlags.Static,
            null, instance, null);
        // private static bool bordValidatie
        objType.InvokeMember("bordValidatie",
            BindingFlags.InvokeMethod | BindingFlags.Instance | BindingFlags.Static,
            null, instance, null);
    }

[AttributeUsage(AttributeTargets.Class)]
public class myPluginAttribute : Attribute
{
    private bool _bIsPlugin;
    public Boolean IsPlugin
    {
        get { return _bIsPlugin; }
        set { _bIsPlugin = value; }
    }
    private string _sDescription;
    public string Description
    {
        get { return _sDescription; }
        set { _sDescription = value; }
    }
    public myPluginAttribute(Boolean b, String desc)
    {
        IsPlugin = b;
        Description = desc;
    }
}
NQueens(单击菜单项时我想加载的程序)NQueens.cs
public class NQueen
{
   public static bool berekenQueens(int Row, int N, bool[,] bord)
   {
       if (Row >= N) return true; 
       for (int Col = 0; Col < N; Col++)
       {
           //Q toevoegen
           bord[Row, Col] = true;
           //Q + Q volgende Row  controleren
           if (bordValidatie(Row, Col, bord, N) && berekenQueens(Row + 1, N, bord))
           {
               return true;
           }
           //Q verwijderen indien niet door controle
           bord[Row, Col] = false;
       }
       return false;
   }
   private static bool bordValidatie(int currentRow, int currentCol, bool[,] currentBord, int N)
   {
       int colstep = 1;
       for (int i = currentRow - 1; i >= 0; i--)
       {
           //rechte lijn 
           if (currentBord[i, currentCol])
               return false;
           //linker diagonaal
           if (currentCol - colstep >= 0)
           {
               if (currentBord[i, currentCol - colstep])
                   return false;
           }
           //rechter diagonaal
           if (currentCol + colstep < N)
           {
               if (currentBord[i, currentCol + colstep])
                   return false;
           }
           colstep += 1;
       }
       return true;
   }
}
主窗口(nqueens)
public partial class MainWindow : Window
{
    public int iN { get { return Convert.ToInt32(txtN.Text); } set { txtN.Text = "" + value; } }
    private bool[,] spelbord;
    public MainWindow()
    {
        InitializeComponent();
    }
    private void button1_Click(object sender, RoutedEventArgs e)
    {
        spelbord = new bool[iN, iN];
        NQueen.berekenQueens(0, iN, spelbord);
        visualise(iN, spelbord);
    }
    private void visualise(int N, bool[,] bord)
    {
        gridTekenen();
        for (int row = 0; row < N; row++)
        {
            for (int col = 0; col < N; col++)
            {

                rect.SetValue(Grid.ColumnProperty, col);
                rect.SetValue(Grid.RowProperty, row);
                txtB.SetValue(Grid.ColumnProperty, col);
                txtB.SetValue(Grid.RowProperty, row);
                gridPaneel.Children.Add(rect);
                gridPaneel.Children.Add(txtB);
            }
        }
    }

        int grooteGrid = int.Parse(txtN.Text);
        RowDefinition rowDef;
        ColumnDefinition colDef;
        for (int i = 0; i < grooteGrid; i++)
        {
            rowDef = new RowDefinition();
            GridLengthConverter myGridLengthConverter = new GridLengthConverter();
            GridLength gl1 = (GridLength)myGridLengthConverter.ConvertFromString(150 + "*");
            rowDef.Height = gl1;
            colDef = new ColumnDefinition();
            colDef.Width = gl1;
            gridPaneel.RowDefinitions.Add(rowDef);
            gridPaneel.ColumnDefinitions.Add(colDef);
        }
    }
}
我一直试图让这件事正常工作。如何让我的程序显示 NQueens 程序?我的客户端程序如何知道 NQueen 的方法并使用它们?
编辑:我对 nQueensToolStripMenuItem_Click 方法进行了一些更改。现在这正确吗?现在如何在我的窗口中显示 NQueens 方法?
