windows form application

Question

currently i am making GUI for my program. for this i need to read No. or integer or string (single word) from text file. I am using visual studio 2005 c++ CLI windows form application.
for reading text file i use streamreader.
there is an option for reading whole line(using readline) or whole file(using read to end).
can anyone tell me how to read specific no. or integer from each line of whole text file?
Thanking you in anticipation.
