How do I reference a field in Linq based on a dynamic fieldname

Question

Firstly, apologies for the bad question title - not entirely sure if I am asking the correct thing.

Normally I can do the following to access a field:

In order to do this, you will need to use reflection.

public object GetField(object obj, string fieldName) { 
  var t = obj.GetType();
  var field = t.GetField(fieldName);
  return field.GetValue(obj);
}

somevalue = GetField(table, "someFieldName");

This works as long as the field is both instance and public. You'd need to modify the GetField method call slightly if the accessibility was less than public.
