public bool ison{get:set}

这是一个 C# 属性,表示一个布尔值是否为真。它包括一个 get 访问器和一个 set 访问器,用于获取和设置属性的值。例如:
```
public bool IsOn { get; set; }
```
可以通过以下方式使用该属性:
```
var myObject = new MyClass();
myObject.IsOn = true;
bool isOn = myObject.IsOn;
```
在这个例子中,我们创建了一个名为 `IsOn` 的属性,并将它的值设置为 `true`。我们还使用 `IsOn` 属性获取了一个布尔值。
注意,属性名称应该以大写字母开头,符合 PascalCase 命名约定。

Use c # to complete the following code,Creating a Car class A class is a self-contained piece of software that is able to function on it own. We will model a car in software. Car Class Properties Year : int «private set» Manufacturer : string «private set» Model : string «private set» IsDrivable : bool «private set» Price : double «private set» Methods«constructor» Car(year : int, manufacturer : string, model : string, price : double, isDrivable: bool = true) PrintInfo() : void Description of field members: 1. year: this private member represents the year value of this object 2. manufacturer: this private member represents the manufacturer of this car 3. model: this private member represents the model of this car 4. isDrivable: this private member indicates if this car be driven 5. price: this private member represents the selling price of this car Constructor: 1. public Car(int year, string manufacturer, string model, double price, bool isDrivable = true): this is the constructor of this class. It takes five arguments and assigns them to the appropriate fields. You will assume that all the arguments will be sane (i.e. the values will not break your program). Apology: UML and some newer languages specify the type after the identifier. C# on the other hand requires that you specify the type and then the identifier
Sure, here is the completed code:
```
public class Car
{
public int Year { get; private set; }
public string Manufacturer { get; private set; }
public string Model { get; private set; }
public bool IsDrivable { get; private set; }
public double Price { get; private set; }
public Car(int year, string manufacturer, string model, double price, bool isDrivable = true)
{
Year = year;
Manufacturer = manufacturer;
Model = model;
Price = price;
IsDrivable = isDrivable;
}
public void PrintInfo()
{
Console.WriteLine($"Year: {Year}, Manufacturer: {Manufacturer}, Model: {Model}, IsDrivable: {IsDrivable}, Price: {Price}");
}
}
```
This code defines a Car class with the specified properties and methods. The constructor takes in the necessary arguments to initialize the object, and the PrintInfo method prints out the information about the car object.
C# 指示灯控件使用
以下是使用C#自定义指示灯控件的步骤:
1. 首先,你需要在Visual Studio中创建一个新的WinForm项目。
2. 在解决方案资源管理器中,右键单击项目名称,然后选择“添加”>“用户控件”。
3. 在“添加新项”对话框中,选择“用户控件”模板,将名称设置为“IndicatorLightControl”,然后单击“添加”。
4. 在“IndicatorLightControl.cs”文件中,添加以下代码:
```csharp
public partial class IndicatorLightControl : UserControl
{
private bool _isBlinking = false;
private bool _isOn = false;
private Color _onColor = Color.Green;
private Color _offColor = Color.Red;
private int _blinkInterval = 500;
public IndicatorLightControl()
{
InitializeComponent();
}
public bool IsBlinking
{
get { return _isBlinking; }
set
{
_isBlinking = value;
if (_isBlinking)
{
blinkTimer.Start();
}
else
{
blinkTimer.Stop();
_isOn = false;
this.BackColor = _offColor;
}
}
}
public bool IsOn
{
get { return _isOn; }
set
{
_isOn = value;
if (_isOn)
{
this.BackColor = _onColor;
}
else
{
this.BackColor = _offColor;
}
}
}
public Color OnColor
{
get { return _onColor; }
set
{
_onColor = value;
if (_isOn)
{
this.BackColor = _onColor;
}
}
}
public Color OffColor
{
get { return _offColor; }
set
{
_offColor = value;
if (!_isOn)
{
this.BackColor = _offColor;
}
}
}
public int BlinkInterval
{
get { return _blinkInterval; }
set
{
_blinkInterval = value;
blinkTimer.Interval = _blinkInterval;
}
}
private void blinkTimer_Tick(object sender, EventArgs e)
{
_isOn = !_isOn;
if (_isOn)
{
this.BackColor = _onColor;
}
else
{
this.BackColor = _offColor;
}
}
}
```
5. 在“IndicatorLightControl.Designer.cs”文件中,添加以下代码:
```csharp
partial class IndicatorLightControl
{
private System.ComponentModel.IContainer components = null;
private System.Windows.Forms.Timer blinkTimer;
private void InitializeComponent()
{
this.components = new System.ComponentModel.Container();
this.blinkTimer = new System.Windows.Forms.Timer(this.components);
this.SuspendLayout();
//
// blinkTimer
//
this.blinkTimer.Tick += new System.EventHandler(this.blinkTimer_Tick);
//
// IndicatorLightControl
//
this.BackColor = System.Drawing.Color.Red;
this.Name = "IndicatorLightControl";
this.Size = new System.Drawing.Size(20, 20);
this.ResumeLayout(false);
}
}
```
6. 在你的WinForm中,将“IndicatorLightControl”控件拖放到你的窗体上。
7. 在属性窗口中,你可以设置控件的颜色、是否闪烁以及闪烁速度等属性。
