Question

我想知道如何将一个double值从一个类发送到另一个类。我正在使用Kinect，当我的公共课主要计算双倍的“距离”时，我会关闭手，我希望将这些信息发送给我的其他公共类Monitor。由于我是C＃编程的初学者，所以示例将非常受欢迎。

private void DrawHand(HandState handState, Point handPosition, DrawingContext drawingContext)
    {
        switch (handState)
        {
            case HandState.Closed:
                drawingContext.DrawEllipse(this.handClosedBrush, null, handPosition, HandSize, HandSize);
                // Distance calculation
                foreach (var body in bodies)
                {
                    // Get the positions
                    pRH = body.Joints[JointType.HandRight];
                    pLH = body.Joints[JointType.HandLeft]; // pLH gets to be "home" position in the meanwhile
                    //Some maths
                    double sqDistance = Math.Pow(pRH.Position.X - pLH.Position.X, 2) +
                        Math.Pow(pRH.Position.Y - pLH.Position.Y, 2) +
                        Math.Pow(pRH.Position.Z - pLH.Position.Z, 2);


                    // This is the information I want to send to public class Monitor
                    double distance = Math.Sqrt(sqDistance);

                }
                break;
        }
    }

Answer 1

我不确定您要实现的目标，但是您可以通过

返回值

return value;

调用类由

接收

double temp = method();

如果您尝试将值double发送到某个类，则应使用参数。

例如： -

Monitor monitor1 = new Monitor(distance);

或

Monitor monitor1 = new Monitor();
monitor1.setDistance(distance);

Answer 2

我不确定我明白你的问题是你想要的

 public class Monitor
        {      
public  Monitor(double distance)//Constructor with double as parameter 
            {

            }
        }

实例化此类时

Monitor mo=new Monitor(distance);

Answer 3

您可以通过多种方式将距离变量发送到监控班级

<强> 1。构造

<强> 2。属性

第3。方法

private void DrawHand(HandState handState, Point handPosition, DrawingContext drawingContext) { switch (handState) { case HandState.Closed: drawingContext.DrawEllipse(this.handClosedBrush, null, handPosition, HandSize, HandSize); // Distance calculation foreach (var body in bodies) { // Get the positions pRH = body.Joints[JointType.HandRight]; pLH = body.Joints[JointType.HandLeft]; // pLH gets to be "home" position in the meanwhile //Some maths double sqDistance = Math.Pow(pRH.Position.X - pLH.Position.X, 2) + Math.Pow(pRH.Position.Y - pLH.Position.Y, 2) + Math.Pow(pRH.Position.Z - pLH.Position.Z, 2); // This is the information I want to send to public class Monitor double distance = Math.Sqrt(sqDistance); // Create object of Monitor class and pass the distance Moniotr obj = new Monitor(distance); // using Method Moniotr obj = new Monitor(); obj.setDistance(distance); // using public property Moniotr obj = new Monitor(); obj.Distance = distance; } break; } }

以下是带有构造函数方法的Sample Monitor类

public class Monitor { public Monitor(double distance) { } }

以下是Sample Monitor Class With Method方法

public class Monitor { public void setDistance(double distance) { } }

以下是带有Property方法的Sample Monitor类

public class Monitor { private double _distance; public Distance { get{return _distance;} set{_distance=value;} } }

在C＃中将一个类的double值发送到另一个类
