Remove Multiple Fields in InfoTable

Hi, 

My Infotable has around 21 Fields, for an particular situation I need just one Field Results, how can I remove unwanted feilds at a time instead of doing the following coding:

result.RemoveField("X1");
result.RemoveField("X2");
result.RemoveField("X3");
result.RemoveField("X4");
result.RemoveField("X5");
result.RemoveField("X7");
result.RemoveField("X8");
result.RemoveField("X9");
result.RemoveField("X10");
result.RemoveField("X11");
result.RemoveField("X12");
result.RemoveField("X13");
result.RemoveField("X14");
result.RemoveField("X15");
result.RemoveField("X16");
result.RemoveField("X17");
result.RemoveField("X18");
result.RemoveField("X19");
result.RemoveField("X20");

is there a query or any shortcut to remove all the Fields at a time ?
