Let's say there's a class called Student

public class Student 
{
     public string studentId {get; set;}
     public string Name {get; set;}
     public int age {get; set;} 
}

I want to get the value from the property age in Student object, how do I do that dynamically? As in, I have a string x, and want to get the value from property x in student object, how can I retrieve the value that belongs to property x?

Switch/case? Or reflection if you want to go that route but in both cases you’ll have to handle situations where such an attribute doesn’t exist. Is this possibly an XY problem? What do you need this for? – Sami Kuhmonen Apr 03 '19 at 06:59
Have a look at *Reflection*: `int result = (int)typeof(Student).GetProperty("age").GetValue(myStudent, new object[0]);` – Dmitry Bychenko Apr 03 '19 at 07:00

They are called `property` in c# tho. – ilkerkaran Apr 03 '19 at 07:00
@DmitryBychenko what does `new object[0]` do here? – superninja Apr 03 '19 at 07:03

@superninja: since we *don't* call *indexer* (but a simple property) we provide an *empty array of indexes* - `new object[0]` – Dmitry Bychenko Apr 03 '19 at 07:05
