在program类中,我希望从这段代码中调用对象、方法和属性,以显示重新分级机器人状态的信息,例如机器人原点、方向和位置。我希望控制台显示如下内容:
String.Format("Robot has home at <{0},{1}> It is facing {2} and is currently at <{3},{4}>",
Home.X, Home.Y, Orientation, Position.X, Position.Y);
机器人在家里
它朝北,目前正处于
有什么办法可以做到这一点吗?首先,我建议您阅读。这将使您的代码看起来像:
public Point Home { get; private set; }
public Point Position { get; private set; }
public Compass Orientation { get; private set; }
现在回到将机器人格式化为字符串。您可以重写robot类的ToString()
方法:
public override string ToString()
{
return String.Format("Robot has home at {0} It is facing {1} and is currently at {2}",
mHome, mOrientation, mPosition);
}
或者只需将robot实例传递给以下方法:
public void WriteToConsole(BaseRobot robot)
{
Console.WriteLine("Robot has home at {0} It is facing {1} and is currently at {2}",
robot.Home, robot.Orientation, robot.Position);
}
注意:默认情况下,System.Drawing.Point类将转换为字符串{X=42,Y=8}
。如果需要将其格式化为
,则应手动为X和Y提供如下值:
String.Format("Robot has home at <{0},{1}> It is facing {2} and is currently at <{3},{4}>",
Home.X, Home.Y, Orientation, Position.X, Position.Y);

请尝试Console.WriteLine,调用类方法以获取参数值,有关详细信息,请参见此处
请尝试Console.WriteLine,调用类方法以获取参数值,有关详细信息,请参阅此处 可以轻松实现这一点 您可以这样使用:
// Assumes a Robot r exists already
Console.Writeline("Robot has home at <{0},{1}> and is facing {2} and is currently at <{3},{4}>", r.Home.X, r.Home.Y, r.Orientation, r.Position.X, r.Position.Y);
//假设机器人r已经存在
Writeline(“机器人的原点位于且正对着{2},当前位于”,r.home.X,r.home.Y,r.Orientation,r.Position.X,r.Position.Y);
另一种方法是:
public override string ToString(){
return string.Format("Robot has home at <{0},{1}> and is facing {2} and is currently at <{3},{4}>", Home.X, Home.Y, Orientation, Position.X, Position.Y);
}
public重写字符串ToString(){
返回string.Format(“Robot在家中,面向{2},当前在家中”,home.X,home.Y,Orientation,Position.X,Position.Y);
}
但是,在这里重写ToString()似乎不正确,因为您显示的机器人状态信息实际上不是“机器人的字符串表示”,而这正是ToString()应该提供的。我要么使用上面的Console.Writeline方法,要么在Robot上有一个string Status属性来获取此类信息。可以很容易地实现这一点
