Changing String Name in a For Loop

Hello

Could you please help me with the following loop. I want to change Item number in every iteration. for exapme when i==1, it reads:

ProtocolName{i}=DIIinfoT.DirectoryRecordSequence.Item_1.ProtocolName;

when it is 2, it reads

ProtocolName{i}=DIIinfoT.DirectoryRecordSequence.Item_2.ProtocolName;

etc.

for i=1:500

ProtocolName{i}=DIIinfoT.DirectoryRecordSequence.Item_(i).ProtocolName;

end

In that line replace

 .item_(i)

with

 .(sprintf('item_%d', i))

The () are important for this purpose.
