Extension method for strongly typed property access

Question

I have the following class hierarchy

class Test
{
    public string Name { get; set; }
}

class TestChild : Test
{
    public string Surname { get; set; }
}

I can't change the Test class. I want to write following extension method like this:

static class TestExtensions
{
    public static string Property<TModel, TProperty>(this Test test, Expression<Func<TModel, TProperty>> property)
    {
        return property.ToString();
    }
}

To be able to use it in the following way:

class Program
{
    static void Main(string[] args)
    {
        TestChild t = new TestChild();
        string s = t.Property(x => x.Name);
    }
}

But now compiler says

The type arguments for method 'ConsoleApplication1.TestExtensions.Property(ConsoleApplication1.Test, System.Linq.Expressions.Expression>)' cannot be inferred from the usage. Try specifying the type arguments explicitly.

I want to have something like mvc Html.TextBoxFor(x => x.Name) method. Is it possible to write extension to be used as shown in the Main method?

Answer 1

static class TestExtensions
{
    public static string Property<TModel, TProperty>(this TModel test, Expression<Func<TModel, TProperty>> property)
    {
        return property.ToString();
    }
}

The compiler should be able to infer the first argument...
