Calculate the unique metrics in a file

[karry086]

For e.g. i have a log file in which there are many entries for appGUID. Now how many appGUID's are there, for this i have a code, but how many of them are unique, for this i don't have code. Please can anyone help me on this.

I have a perl script that finds the number of unique users in a log file by calling the function 'print_unique_u sers'. Following is the perl script :

function num_unique_users() {echo `print_unique_users 0 | gawk -F"," '{counts[$1]+=1}; END { print length(counts)}'` }

Now this same logic i want to apply in C sharp language. Can you help ?

Actually i wanted to parse logs to find unique entries in a file for a particular field. My file has the log entries in following format :

User:ashishg appGUID: wx
User:weqeld appGUID: c09d24cb-bb4f-422b-963a-9cbd00d203cc
User:weqeld appGUID: c09d24cb-bb4f-422b-963a-9cbd00d203cc
User:gulanand appGUID: wx
User:gulanand appGUID: wx

Now i wanted to calculate unique appGUID/User from this log file. How can i do that using C sharp program ?

Please use code tags when posting code.

The general algorithm to deduplicate a series of values is this:
0) Create an array
1) Loop through each value
2) Check if the value is in the array
3) If not, add it to the array
