Hi all,
How would I go about this?
I am doing a document management system and I need to write a clean up
routine.
I will create two arrays. One of them will have a list of filenames I have
dragged from a database (I actually have to parse strings to get filenames,
but I can already do that). I will be inserting the file names into an
arraylist.
The second arraylist will be a result of reading the filesystem.
What I want to do is then cross compare. Basically, any surplus files from
the filesystem arraylist will be deleted, so I need to know if the file in
the filesystem is in the filelist from the database.
Any ideas on how I can do this would be appreciated.
Best regards,

The arraylist contains a useful member called Contains. I'd make use of it.
foreach (string file in fileSystemList)
{
if (!databaseList. Contains(file))
{
//file needs to be deleted
}
}

Hi
Hopefully I am missing something really simple with this question, but
here goes.
I have two Bitarrays that I would like to compare. At the moment, I am
XORing one with the other and checking to see if the result has any 1s
in it (if so, the arrays are different). This seems to be faster than
comparing each bit of the two original arrays one at a time. But I
still have to iterate over each element of the array, and I'd like to

I have two char arrays of size k.
I want to know which one is bigger (exactly like for instance
I compare two ints/longs/etc.).
What is the fastest way to do this? k <= 10 usually for my application.
I tried bcmp / a loop for comparison, but it seems they are very slow
compared to comparing longs...Any ideas?
I tried splitting the array into longs and comparing, but then
I face the high endian/low endian problem on some machines.

First off, I know arrays can't be compared directly (ie: if (arrary1

pointers with no success. Basically, I want to take three sets of
character strings from the user. Then I want to run through each
element and compare the two strings. If they match I print they
match... I'm having a bit of trouble with the actual loop through each

If I have two arrays, what is a good paradigm for comparing what is in
them, to determine what elements they share, or don't share?
Specifically, each array could potentially contain the integers 1 to
9, but probably not all 9 integers.
MyArray1 = 1,2,3,5,6,7,8
MyArray2 = 1,4,6,7
I would need the answers to be arrays too:

Hi,
I need to compare two timestamp columns in sql server and see which one
is greater. (i can tell if they are not equal buts not enough for this
requirement).
A timestamp value is unique in a database and always increments. A
non-null timestamp is type Binary(8) in sql server and I pass it to a
byte array in C#. To compare the two byte arrays I use
BitConverter.ToUInt64, as this converts an 8 byte array to a 64 bit

How does the GetHashCode() of an array object behave?
Does it combine the GetHashCode() of its elements, or does
it create a sync block for the object?
I want to use readonly arrays as dictionary keys, based on
their content, not their identity. Is this feasible using the
arrays directly, or do I need to wrap them in a struct that
handles GetHashCode and Equal? If so, is such a wrapper
present in the standard class library?

Hi,
I have two arrays that are identical and contain 1s and zeros. Only the
ones are valid and I need to know where both arrays have ones in the
same position. I thought logical_and would work but this example proves
otherwise:
>>> a =
>>> b =
>>> Numeric.logical_and(a==6,b==6)
0

Hi folks,
I am comparing two arrays and removing matches from the second array
from the first array.
Can someone take a look at this code below and mention if this is okay
and perhaps if there is a better way to achieve it

for(j=0;j<arrayB.length;j++){
if(arrayA==arrayB)

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows.

For most users, this new feature is actually very convenient. If you want to control the update process,...
