在控制台应用程序中使用Reflection动态创建和调用类 [英] Dynamically creating and calling a class using Reflection in a console application

问题描述

我在使用C＃语言的本节中有一些问题。

I have some problems about this section in C# language.

因此，我正在尝试做一些事情，例如揭示此类及其方法的反映。

So I'm trying to do something like revealing reflection of this class and it's methods.

class Car
{
    public string Name { get; set; }
    public int Shifts{ get; set; }


    public Car(string name, int shifts)
    {
        Name = name;
        Shifts = shifts;
    }

    public string GetCarInfo()
    {
        return "Car " + Name + " has number of shifts: " + Shifts;
    }

}

所以我有这个汽车类，这个方法GetCarInfo （），现在，我正在尝试：
动态创建此类Car的实例，并动态调用方法GetCarInfo（），我想在控制台中显示结果，但是在运行它时无法显示它显示了构建错误。应用程序每次都会中断。

So I have this class Car, and this method GetCarInfo(), now, I'm trying to: Dynamically create instance of this class Car, and dynamically calling a method GetCarInfo(), I would like to show result in console, but I can't when I run it it shows build errors. The application break every time.

错误

推荐答案

以下是示例

namespace ConsoltedeTEstes
  {
 class Program
 {
    static void Main(string[] args)
    {
        //Get the type of the car, be careful with the full name of class
        Type t = Type.GetType("ConsoltedeTEstes.Car");

        //Create a new object passing the parameters
        var dynamicCar = Activator.CreateInstance(t, "User", 2);

        //Get the method you want
        var method = ((object)dynamicCar).GetType().GetMethod("GetCarInfo");

        //Get the value of the method
        var returnOfMethod = method.Invoke(dynamicCar, new string[0]);

        Console.ReadKey();
    }
}

public class Car
{
    public string Name { get; set; }
    public int Shifts { get; set; }


    public Car(string name, int shifts)
    {
        Name = name;
        Shifts = shifts;
    }

    public string GetCarInfo()
    {
        return "Car " + Name + " has number of shifts: " + Shifts;
    }

}


}
