Static Reflection

Get property internal names without using System.Reflections

I am having a list of Person as follows:

var obj = new List<Person> { new Person { ID = 1, Name = "Arunava" }, new Person { ID = 2, Name ="Bubu" } };

My goal is to get the output as :

Name=Arunava ID=1
Name=Bubu ID=2

in the console. Let's see how we can achieve that without using reflection. I used Linq.Expressions to achieve this.

Simple method to add in your model class, called GetPropertyName and also change the ToString method. My model class is as follows:

public class Person
{
    public string Name { get; set; }
    public int ID { get; set; }
    public string GetPropertyName<T>(Expression<Func<T>> propertyLambda)
    {
        var me = propertyLambda.Body as MemberExpression;
        return me.Member.Name;
    }
    public override string ToString()
    {
        return String.Format("{0}={1} {2}={3}", GetPropertyName(() => Name), Name,GetPropertyName(()=>ID),ID);
    }
}

We are ready to get the expected result. See my console app:

var obj = new List<Person> { new Person { ID = 1, Name = "Arunava" }, new Person { ID = 2, Name ="Bubu" } };
obj.ForEach(data=> Console.WriteLine(data));

Try this now. Hope this helps.
