Can Reflection Change a C# Property's Value Given its Name?

Setting Property Value Using Reflection

Question:

Is it feasible to use reflection to alter a property's value in C#, given that the property name is known?

Answer:

Absolutely, reflection enables this functionality. Here's how to achieve it:

1. Fetch the Property: Utilize Type.GetProperty method to obtain the target property. You may need to specify additional binding flags to ensure accessibility.
2. Set the Value: Invoke SetValue method on the retrieved property. Here's a code example to illustrate:

using System;

class Person
{
    public string Name { get; set; }
}

class Test
{
    static void Main(string[] arg)
    {
        Person p = new Person();
        var property = typeof(Person).GetProperty("Name");
        property.SetValue(p, "Jon", null);
        Console.WriteLine(p.Name); // Jon
    }
}

Note: If the target property is non-public, you'll need to employ BindingFlags.NonPublic | BindingFlags.Instance when fetching the property.
