Inspecting methods and properties in C Sharp (C#) - Mini Project: Build & Apply

Inspecting methods and properties

📖 Scenario: Imagine you have a simple class representing a car. You want to learn how to look inside this class to see what methods and properties it has. This is useful when you want to understand or use a class without reading all its code.

🎯 Goal: You will create a class called Car with some properties and methods. Then, you will write code to inspect and list all the methods and properties of the Car class using reflection.

📋 What You'll Learn

Create a class Car with properties and methods

Create a variable to hold the Type of the Car class

Use reflection to get all methods and properties of the Car class

Print the names of all methods and properties

💡 Why This Matters

🌍 Real World

Inspecting methods and properties helps developers understand and use classes from libraries or frameworks without reading all the source code.

💼 Career

Reflection is useful in debugging, building tools, and frameworks that need to work with unknown or dynamic types at runtime.

1

Create the Car class with properties and methods

Create a class called Car with two public properties: Make of type string and Year of type int. Also add a public method called StartEngine that returns void and has no parameters.

C Sharp (C#)

// Your code here

Need a hint?

Use public class Car to start the class. Add properties with public string Make { get; set; } and public int Year { get; set; }. Add a method public void StartEngine().

2

Get the Type object for the Car class

Create a variable called carType and set it to the Type of the Car class using typeof(Car).

C Sharp (C#)

public class Car
{
    public string Make { get; set; }
    public int Year { get; set; }

    public void StartEngine()
    {
        // Engine starting logic
    }
}

// Your code here

Need a hint?

Use Type carType = typeof(Car); to get the type information of the Car class.

3

Use reflection to get methods and properties

Create two variables: methods and properties. Set methods to carType.GetMethods() and properties to carType.GetProperties().

C Sharp (C#)

public class Car
{
    public string Make { get; set; }
    public int Year { get; set; }

    public void StartEngine()
    {
        // Engine starting logic
    }
}

Type carType = typeof(Car);

// Your code here

Need a hint?

Use carType.GetMethods() to get all methods and carType.GetProperties() to get all properties.

4

Print the names of all methods and properties

Use a foreach loop to print the name of each method in methods and each property in properties. Use Console.WriteLine to print each name.

C Sharp (C#)

public class Car
{
    public string Make { get; set; }
    public int Year { get; set; }

    public void StartEngine()
    {
        // Engine starting logic
    }
}

Type carType = typeof(Car);

var methods = carType.GetMethods();
var properties = carType.GetProperties();

// Your code here

Need a hint?

Use foreach (var method in methods) { Console.WriteLine(method.Name); } and similarly for properties.
