Members are different than properties (which Viv already mentioned). In your case, if you need to access a member (and not a property) and retrieve it's value, that would look like this:

var dataSource = new SampleA();
dataSource.Test = 5;
var memberInfo = dataSource.GetType().GetMember("Test");
if (memberInfo.Length > 0)
{
	var member = memberInfo[0];
	var field = (FieldInfo)member;
	field.GetValue(dataSource).Dump();
}

public class SampleA
{
	public int Test;
}

Or in VB

Dim dataSource = New SampleA()
dataSource.Test = 5
Dim memberInfo = dataSource.GetType().GetMember("Test")
If memberInfo.Length > 0 Then
	Dim member = memberInfo(0)
	Dim field = CType(member, FieldInfo)
	field.GetValue(dataSource).Dump()
End If

Public Class SampleA
	Public Test As Integer
End Class
