How would you code an alternative to NameOf using Reflection. I am using VS 2010 and NameOf is not available. I need to get the names of any Members of any Type in the hierarchy of the Structure.

Structure Market
    Public Vehicle As Vehicle
    Public Place As String
End Structure

Structure Vehicle
    Public [Color] As Color
End Structure

Dim Market As String = NameOf(GetType(Market)) ' "Market"
Dim Vehicle As String = NameOf(GetType(New Market().Vehicle)) '"Vehicle" or "Market.Vehicle"
Dim Place As String = NameOf(GetType(New Market().Place)) '"Place" or "Market.Place"

What I have tried:

Function NameOf(Of T)(ByVal expression As T) As String

End Function

Most probably you will find nothing...Nameof Operator: A New Feature of C# 6.0[^]

does GetType(???).FullName not work for you?

Yes, but I also need the variable name not just the name of it's underlying type.

Reflection won't work because, in your example, every call to GetType is going to return System.String, or whatever the type of the variable is. You're not going to find your variable name on any instance of the Type class.

It can be done using an Expression Tree, but this its expensive to execute. Use this code in any case where you have to execute it thousands of times a second and you're going to notice quite the performance hit.
class Program
    static void Main(string[] args)
        string Market = string.Empty;

        Console.WriteLine(Ext.GetNameOf(() => Market));


public static class Ext
    public static string GetNameOf<T>(Expression<Func<T>> expression)
        var body = (MemberExpression)expression.Body;

        return body.Member.Name;

This is an overload for parameters of Type
Dim market2 As Market 'structure
Dim structName$ = GetNameOf(Of Market)() 'returns 
Function GetNameOf(Of T)() As String             
    Return GetType(T).Name    
End Function
