Getting property value based on custom attribute value

I have a set up similar to this one:

public class MyAttribute : Attribute
    {
        public string ConfigName { get; set; }
    }

    public class PropertyClass
    {
        [MyAttribute(ConfigName = "Some")]
        public string MyProperty { get; set; }

        public object PropertyValueByAttribute(string attributeName)
        {
            return this.GetType().GetProperties().Where(x => ((MyAttribute)(x.GetCustomAttributes(typeof(MyAttribute), false)[0])).ConfigName == "Some").ToList()[0].GetValue(this, null);
        }
    }

Now, I am trying to find value of MyProperty based on value of the ConfigName parameter for the property attribute. There's a lot of reflection and casting going on here. Is there a better way to achieve this?

P.S. Sorry for the long LINQ statement. I am just trying to figure out the way and ended up with this. Ain't gonna happen in real application.
