msgpack和TParams互相转换

procedure msgpack2params(const Source: TMsgPack; Dest: TParams);
var
  ps: TParams;
  p: TParam;
  i: Integer;
begin

  try
    for i := 0 to Source.Count - 1 do
    begin

      p.Value := Source.Items[i].AsVariant;
    end;
    Dest.Assign(ps);
  finally
    ps.Free;
  end;
end;
