Linux

hi everyone,i have winform visual studio 2012 and a server running in linux.

i have to get some status of the server from my winform.
for exemple: the total number of internet connections opened on server, the number of opened socket(tcp) opened, number of connections per socket, memory usage, and disk space of server used.

during my reseach, i found all the linux commands to get what i want. but now the problem is how i can from my winform run these linux commands and display the result ?

What I have tried:

free -m // to get all details about memory
df -h // disk space details
netstat -l |wc -l // total number of sockets opened
netstat  -at |wc -l //total number of opened tcp sockets opened
netstat -an |grep -w 80|wc -l //number of active connections on port 80
