Use reflection to get the value of a property by name in a class instance

Question

Lets say I have

class Person
{
    public Person(int age, string name)
    {
        Age = age;
        Name = name; 
    }
    public int Age{get;set}
             


        

Answer 1

You can do something like this:

Person p = new Person( 10, "test" );

IEnumerable fields = typeof( Person ).GetFields( BindingFlags.NonPublic | BindingFlags.Instance );

string name = ( string ) fields.Single( f => f.Name.Equals( "name" ) ).GetValue( p );
int age = ( int ) fields.Single( f => f.Name.Equals( "age" ) ).GetValue( p );

Keep in mind since these are private instance fields you need to explicitly state the binding flags in order to get them via reflection.

Edit:

It seems you changed your sample from using fields to properties, so I'm just going to leave this here in case you change back again. :)
