Array question

[Chickenman]

Okay I am hoping you all can point me in the correct direction. I am new to the whole C#, .NET stuff but here we go. I have an app that gets a listing of files, and then uses a streamreader to find a specific line in the file and adds this along with the UNC to the filename to an arraylist.

My problem is this:

I get it to display the information in the format of:

fieldA-fieldB,\\servershare\filename

The problem I am trying to resolve is that there can be duplicates in this list for FieldA and B. I need to find all the files that have the same fieldA and B in the list and display them. The differing filenames is what is holding me up I believe.

Has anyone run across anything that might help me out? Google is your friend, but you have to know what to google first ;)

Any help would be GREATLY appreciated!

Well, if I understand your question correctly, you have strings in this format:
fieldA-fieldB,\\servershare\filename
and you need to find all that have a common fieldA-fieldB?

Well, if fieldA and fieldB don't have commas in them, you could split the string around a comma, and then compare the first part of the results.

char[] delims = { ',' };
string[] tokens = stringToSplit.Split(delims);
//now tokens[0] should have fieldA-fieldB
 

So you could add tokens[0] to an array or list and then work your logic to find dups.

Yes I am doing something like this:

string[] llarray = line.Split(',');
                            string labelInfo = llarray[1].ToString() + "-" + llarray[2].ToString();

What is happening is that file A will come along and will look in the empty arraylist and realize it is not in there and add it(which it should do). File B will then come along and see file A and see that it is a duplicate and throw it into Arraylist2.
That part of the logic is working, but where I run into problems is that they want to know which file that FileB is conflicting with.

I think the solution is close, I am obviously just not grasping what I need to do to get the corresponding file in Arraylist1 that is causing the duplicates.

I am sure this is very confusing as I am most likely not saying stuff correctly.

Thanks!

I see. You want to track what filenames that have duplicate fields.

Well, if I were in your shoes, I'd make my own class. Really simple, just three public strings: fieldA, fieldB, and filename. Then, when I parse my string, I'd create a new instance of this class. Then do your comparisons using the class, and add it to the dup/non-dup lists, and you will have all the information tied together.

Hope that helps.
