I remember an array.reverse or something to sort

before sort, get the time stamp, when done get time stamp, and deduct the time using time difference.

That's a good test of skill.

Yep, for the sorting I used Array.Sort(myArray) for ascending. I did the same for descending with Array.Reverse(myArray) afterwards.

How do I do a timestamp? I've never worked with timers before in C# - only in VB and even then it was a very basic thing that counted up in seconds.

Could someone give me some code which times the sort and puts the amount of time into a float or double variable?

I've googled it and found QueryPerfCounter(). Is that what I need to use?

Thanks.

EDIT: I now have the following code:

var start = DateTime.now;
//code here which I am timing
int i = DateTime.Now.Subtract(start).Milliseconds;
TextBox1.Text = Convert.ToString(i);

The last line is just so I can test the answer I get. And I keep getting zero! I guess thats because I'm only measuring hours, minutes and seconds - not milliseconds. Can someone help?

Thank you! Smile | :)

I have now done it, using Stopwatch.

I had tried to use the stopwatch earlier and couldn't get it to work - all because I was missing the namespace using System.Diagnostics Roll eyes | :rolleyes:

I understand your desire to learn, however, I believe the intention of the interview process is to see what you can do, not what others recommend you do, or do for you. If you do manage to get to the next stage of the interview process, do you mention you had help with this? If you manage to get the job, will the employer expect you to deliver, or expect you to ask others?

It is one thing to research a problem; no one is expected to know everything. It is another matter entirely, IMO, to ask for help on such interview, or exam, questions.

Also keep in mind the there may be a good likelihood the person who gave you these questions checks sites like this for people asking questions like this.

It is simply a matter of forming the database query. Something like,

SELECT Title, Summary
WHERE Title CONTAINS('@keyword')

Comparing array of strings

Hi,

I have an asp.net application which loads data from csv file. I need to check for duplicate rows in the csv file and should not process them and give error message for those duplicate rows.

I did in some approach but got the comments like performance is impacted. Is there any performance oriented process available to compare the string arrays

Any type of help is greatly appreciate.

Here is my code

private static bool CheckForDuplicateRow(FileInfo file
            ,string[] line
            ,int lineNumber
            ,ref bool lineAlreadyVerified)
        {
            CsvStream csvStream;

            using (Stream fileStream = file.OpenRead())
            {
                using (StreamReader reader = new StreamReader(fileStream))
                {
                    csvStream = new CsvStream(reader);
                    string[] rowItems;
                    try
                    {
                        csvStream.GetNextRow(); //This is for header values, we are not comparing for header values

                        rowItems = csvStream.GetNextRow();
                        int rownumber = 1;

                        while (rowItems != null)
                        {
                            if ((rowItems.Length == line.Length) && (rownumber != lineNumber) && (rowItems.Length > 0))
                            {
                                bool b = AreRowItemsEqual(rowItems, line);
                                if (AreRowItemsEqual(rowItems, line) == true)
                                {
                                    if (lineNumber < rownumber)
                                        lineAlreadyVerified = true;
                                    return true;
                                }
                            }
         
                   rowItems = csvStream.GetNextRow();
                            rownumber++;
                        }
                    }
                    catch (Exception e)
                    {                        
                        throw e;
                    }
                }
            }

            return false;
        }

        private static bool AreRowItemsEqual(string[] rowItems, string[] line)
        {
            for (int i = 0; i < rowItems.Length; i++)
            {
                if (rowItems[i] != line[i])
                {
                    return false;
                }
            }
            return true;
        }

Here's my approach:

//list to add lines in your csv file
ArrayList uniqueLines = new ArrayList();
ArrayList duplicateLines = new ArrayList();

//Read all lines from your csv file
String[] lines = File.ReadAllLines( "C:/file.csv" );//passing the file path

foreach ( String line in lines )
{
   if ( !uniqueLines.Contains( line ) )
   {
      uniqueLines.Add( line );
   }
   else
   {
      duplicateLines.Add( line );
   }

}

From the above, you have all the unique lines in the uniqueLines arraylist and you have duplicate lines in the duplicateLines arraylist.
To display errors, loop through the "duplicateLines" and tell the user about the error.

Happy Coding,
Morgs

Yes, you can use List<string> if you want. The ArrayList comes from the: using System.Collections;

Hi,

Is there any way to get the which rows are repeated, like for example row 1, 3, 5 are same and 2 and 4 are same.

Is there any way to get that from this list?

this is server side code which will get executed the user clicks a button in your DataList. I am assuming that your expected behavior is not working.

since everything in your script appears to be static why not just write the script code into your .aspx page directly? add your control and on the click event call your javascript function. the only thing you need change is returning false so that it won't post back.

dynamically implement??

there is nothing dynamic about that script that you posted so why not just put it in a static javascript function that gets called from each item in the DataList. the html code that gets displayed is dynamically generated on the server so maybe that is it??

sounds like a homework assignment when you mention it this.. haha

Hi,

I have tried to deploy my web application (VS2010 + C#) by adding the project output and building a msi setup. But, I want to do these steps through command prompt. Our command scripts will do all the stpes to deploy in server.

That command prompt scripts should do the following things

1. Getting latest version of my solution
2. Adding web deployment project and adding project outputs there
3. Building and deploying in a server..

How to do that?

Thanks in advance.
