Example

using System;
using System.Reflection;

public class ExampleClass
{
    public string MyProperty { get; set; }
    private int _myPrivateField;

    public int MyOtherProperty
    {
        get { return _myPrivateField; }
        set { _myPrivateField = value; }
    }
}

public class Program
{
    public static void Main(string[] args)
    {
        Type myType = typeof(ExampleClass);

        // Get all public properties
        PropertyInfo[] properties = myType.GetProperties();

        foreach (PropertyInfo prop in properties)
        {
            Console.WriteLine($"Property Name: {prop.Name}");
            Console.WriteLine($"Property Type: {prop.PropertyType.Name}");
            Console.WriteLine($"Can Read: {prop.CanRead}");
            Console.WriteLine($"Can Write: {prop.CanWrite}");

            // Example of getting and setting a property value
            if (prop.Name == "MyProperty")
            {
                ExampleClass instance = new ExampleClass();
                prop.SetValue(instance, "Hello Reflection!");
                object value = prop.GetValue(instance);
                Console.WriteLine($"Value of {prop.Name}: {value}");
            }
            Console.WriteLine("---");
