我有以下代码，但它没有给我任何输出。我完全不知道接下来要做什么。需要以下输出

四边形的坐标为：( 1.1, 1.2 ), ( 6.6, 2.8 ), ( 6.2, 9.9 ), ( 2.2, 7.4 )

  using System;

  class testquadrilaterals 
  {
static void Main() 
{
    quadrilateral obj1 = new quadrilateral(1.1, 1.2, 6.6, 2.8, 6.2, 9.9, 2.2, 7.4);
    Console.ReadLine();
}
  }

  class point 
  {
private double x;
private double y;

public point(double x_coord, double y_coord)
{
    x = x_coord;
    y = y_coord;
}

public double X { get { return x; } set { x = value; } }
public double Y { get { return y; } set { y = value; } }

public void printcoord()
{
    Console.WriteLine("(" + X + ", " + Y + ")");
}
  }

  class quadrilateral
  {
point p1, p2, p3, p4;

public quadrilateral(double x1, double y1, double x2, double y2,
    double x3, double y3, double x4, double y4)
{
    p1 = new point(x1, y1);
    p2 = new point(x2, y2);
    p3 = new point(x3, y3);
    p4 = new point(x4, y4);
}

public point P1 { get { return p1; } set { p1 = value; } }
public point P2 { get { return p2; } set { p2 = value; } }
public point P3 { get { return p3; } set { p3 = value; } }
public point P4 { get { return p4; } set { p4 = value; } }

public string printcoordinates() 
{
    return "Coordinates of Quadrilateral are " + p1.ToString() + " " + p2.ToString() + " " + p3.ToString() + " ";
}

}

您需要调用您的打印方法：

class testquadrilaterals 
{
    static void Main() 
    {
        quadrilateral obj1 = new quadrilateral(1.1, 1.2, 6.6, 2.8, 6.2, 9.9, 2.2, 7.4);
        Console.WriteLine(obj1.printcoordinates()); // Call your print method
        Console.ReadLine();
    }
}

修复您的打印坐标并调用它：

public void printcoordinates() 
{
    console.writeline("Coordinates of Quadrilateral are " + p1.ToString() + " " + p2.ToString() + " " + p3.ToString() + " ");

}


class testquadrilaterals 
{
    static void Main() 
    {
        quadrilateral obj1 = new quadrilateral(1.1, 1.2, 6.6, 2.8, 6.2, 9.9, 2.2, 7.4);
        obj1.printcoordinates(); // Call your print method
        Console.ReadLine();
    }
}

您point似乎没有ToString覆盖-我认为-您有打印但未连接。

看来您想要的是定义调用该打印的 ToString - 如果我做对了，代码

我会这样做 - 对于point： 

public override string ToString()
{
    return "(" + X + ", " + Y + ")";
}

......对于四级...... 

public override string ToString()
{
    return "Coordinates of Quadrilateral are " + p1.ToString() + " " + p2.ToString() + " " + p3.ToString() + " ";
}

像这样称呼它： 

Console.Write(obj1.ToString());
