C# - Counting Occurrences Of A String In An Array And Then Removing Duplicates?
Jan 2, 2010I am fairly new to C# programming and I am stuck on my little ASP.NET project.
My website currently examines Twitter statuses for URLs and then adds those URLs to an array, all via a regular expression pattern matching procedure. Clearly more than one person will update a with a specific URL so I do not want to list duplicates, and I want to count the number of times a particular URL is mentioned in, say, 100 tweets.
Now I have a List<String> which I can sort so that all duplicate URLs are next to each other. I was under the impression that I could compare list[i] with list[i+1] and if they match, for a counter to be added to (count++), and if they don't match, then for the URL and the count value to be added to a new array, assuming that this is the end of the duplicates.
This would remove duplicates and give me a count of the number of occurrences for each URL. At the moment, what I have is not working, and I do not know why (like I say, I am not very experienced with it all).
With the code below, assume that a JSON feed has been searched for using a keyword into srchResponse.results. The results with URLs in them get added to sList, a string List type, which contains only the URLs, not the message as a whole.
I want to put one of each URL (no duplicates), a count integer (to string) for the number of occurrences of a URL, and the username, message, and user image URL all into my jagged array called 'urls[100][]'. I have made the array 100 rows long to make sure everything can fit but generally, this is too big. Each 'row' will have 5 elements in them.
The debugger gets stuck on the line: if (sList[i] == sList[i + 1]) which is the crux of my idea, so clearly the logic is not working.
Here is sample code:
var sList = new ArrayList();
string[][] urls = new string[100][];
int ctr = 0;
int j = 1;
foreach (Result res in srchResponse.results)
{
string content = res.text;
string pattern = @"((https?|ftp|gopher|telnet|file|notes|ms-help):((//)|(\\))+[wd:#@%/;$()~_?+-=\.&]*)";
MatchCollection matches = Regex.Matches(content, pattern);
foreach (Match match in matches)
{
GroupCollection groups = match.Groups;
sList.Add(groups[0].Value.ToString());
}
}
sList.Sort();
foreach (Result res in srchResponse.results)
{
for (int i = 0; i < 100; i++)
{
if (sList[i] == sList[i + 1])
{
j++;
}
else
{
urls[ctr][0] = sList[i].ToString();
urls[ctr][1] = j.ToString();
urls[ctr][2] = res.text;
urls[ctr][3] = res.from_user;
urls[ctr][4] = res.profile_image_url;
ctr++;
j = 1;
}
}
}
The code then goes on to add each result into a StringBuilder method with the HTML.Is now edite

May 3, 2010I want to remove duplicates from this list:
List<Dictionary<string, object>> val = new List<Dictionary<string, object>>();
It does not work if I apply Distinct() in this way:

Update: Problem is now solved. I used the MySQL union command to read table from the database.

Web Forms :: Remove Duplicates From List Method?
Nov 16, 2010I have a Method that returns 4 records like this.
Name: Test1
Year: 2010
Value: $1000
Name: Test2
Year: 2010
Value: $1000
Name: Test3
Year: 2011
Value: $2000
Name: Test4
Year: 2011
Value: $1000
I need a way to get the unique years just ( 2010, 2011) rather than all 4 years, rest of the data could be duplicates.
Here is the method:
public List<TestCosts> GetTestvalues(string testid)
{
List<TestCosts> testlist = Testscores.List(testid);
return testlist;
}
Most of the examples of removing duplicates I saw have a list of one item only but in my case I have 3 items per record and I need to loop through each record, find the duplicate years, remove them and then return the distinct list of years along with the other data.

I have composed a list of a mixture of abnormal/not abnormal items. I want and need to remove items from this list that aren't clsasified as being abnormal (in programming logic, isAbnormal will be false)
I have tried several ways and can think of some dirty/ugly ways to get it, but there has to be something better:

WCF / ASMX :: Removing A Number From Array List With Web Service?
Mar 25, 2010I need to pass a random number from 1 to 100 from the client to a webservice, and then the webservice will subtract this number from the list of 100 numbers (say 1-100). Then, in the next call, the next random number will be subtracted from the rest 99 numbers and so on.
I need this to be done with AJAX. I don't know where the Array list should be held in the first place (would it be in the web service or in the code behind? ), and how this can be done?

Jquery - Removing Items From Dropdown List (client Side)
Feb 10, 2011So I have a number of dropdown select list controls populated as part of a repeater. They might contain overlapping data, meaning that the first d d list control will have selections:

Second one:
c
d
e
Third one:
d

and so on.
So what I would like to do is to srart removing the duplicate items from the reset of drop down controls once the user starts selecting those. I intend to use jQuery for this.

SQL Server :: How To Union Two Queries Without Duplicates
Aug 27, 2010I have a sql query that returns 4 columns CustName CustId CustZip CustPhone
I have a second sql query that returns the following 5 columns
CustName CustId CustZip CustEmail CustAddress
Both queries, query different data tables in the database, but return columns that are common to
both.
How do I union the two queries(Assuming a union is needed)
Which will result in no duplicates and an end result being the following output:
CustName CustId CustZip CustPhone CustEmail CustAddress
As you can see we want to not have duplicate values on output. So something like the following
is not acceptable:

.net - CssClass Duplicates On An UpdatePanel Update?
Apr 20, 2010I've got a simple user control in my ASP.NET Webforms project which inherits from the LinkButton. It's got a property to change the size, which just adds some predefined CSS classes to the control.
Protected Overrides Sub CreateChildControls()
Dim SizeClass As String = String.Empty
If Size = SizeEnum.Large Then
SizeClass = "large"
[Code]....
So when it renders the class property is something like class="button small".
When this control is placed inside an update panel along with some other things, when the update panel updates the class property for every one of these controls becomes class=" button small button small button small button small button small button small button small button small button small button small button small button small button small"
