Question

The problem I am trying to solve is how to write a method which takes in a property name as a string, and returns the value assigned to said property.

My model class is declared similar to:

public class Foo
{
    public int FooId
    public int param1
    public double param2
}

and from within my method I wish to do something similar to this

var property = GetProperty("param1)
var property2 = GetProperty("param2")

I am currently trying to do this by using Expressions such as

public dynamic GetProperty(string _propertyName)
    {
        var currentVariables = m_context.Foo.OrderByDescending(x => x.FooId).FirstOrDefault();

        var parameter = Expression.Parameter(typeof(Foo), "Foo");
        var property = Expression.Property(parameter, _propertyName);

        var lambda = Expression.Lambda<Func<GlobalVariableSet, bool>>(parameter);

    }

Is this approach correct, and if so, is it possible to return this as a dynamic type?

Answers were correct, was making this far too complex. Solution is now:

public dynamic GetProperty(string _propertyName)
{
    var currentVariables = m_context.Foo.OrderByDescending(g => g.FooId).FirstOrDefault();

    return currentVariables.GetType().GetProperty(_propertyName).GetValue(currentVariables, null);
}

Answer 1

public static object ReflectPropertyValue(object source, string property)
{
     return source.GetType().GetProperty(property).GetValue(source, null);
}
