How to enumerate passed method parameters

One can enumerate the called method parameter types/information like this:

private void SomeMethod(int thisValue, string thatValue)
{
  StackTrace stackTrace = new StackTrace();
  foreach (ParameterInfo pInfo in stackTrace.GetFrame(0).GetMethod().GetParameters())
  {
    string name = pInfo.Name;
    string type = pInfo.GetType().ToString();
  }
}

But is there any way to get the actual object of each parameter?

EDIT: My goal is to enumerate all parameters and get their values. Using LinQ Expressions, one can get the parameter value like so:

private void SomeMethod(int thisValue, string thatValue)
{
  object valueOfThis = GetParameterValue(() => thisValue);
  object valueOfThat = GetParameterValue(() => thatValue);
}
private object GetParameterValue<T>(Expression<Func<T>> expr)
{
  var body = ((MemberExpression)expr.Body);
  return ((FieldInfo)body.Member).GetValue(((ConstantExpression)body.Expression).Value);
}

But what I would like to do is something like:

foreach (fooObject o in thisMethod.GetParameterObjects())
{
  object someValue = GetParameterValue(() => fooObject);
}

And thereby have a generic method for collection all parameters and their values.
