Looping Performance With Conditional C#?

Jan 6, 2011

Which of these will perform better if we assume that the IF block in #1 will be executed more and less in #2

foreach()
{
if
{
block here
}
}
or
foreach()
{
if !( )
continue
}

I've structured #2 to take the if conditional less often.

Configuration :: .Net Website Performance Of 2 Sites - Rectify The DB Performance While Insertion?

Sep 20, 2010

I have developed a website in asp.net framework 2 . This website is being hosted in two different servers without any change in code. My issue is about the performance of these 2 sites. One website is taking much time for inserting datas to the DB (SQL server 2005). 2 websites are having different DB server.

DataSource Controls :: LINQ Performance Application Performance Is Not Up To Par?

Apr 29, 2010

I am not sure if this is the right forum. I can not find a forum for LINQ.

I am working on an application using LINQ. Application performance is not up to par and my tests show that it is LINQ queries that are slow. I was wondering if anybody can recommend where I can find an article about optimizing LINQ performance maybe by compilation or other methods.

For Loop In C# Not Looping

Feb 23, 2011

I have an issue with a Loop that doesn't actually loop. I've posted a simplified version of my code below. Basically, using the NPOI excel library, I have an excel file with data on the first and second sheet, so I need to do a loop to get through both sheets. Below is what I have done so far, however this only works through the first sheet and then exits. It fails to increment the variable w. As you can see, there are other loops implemented in this code which function fine so I don't get it.It's been a very long day and perhaps I'm missing something very simple. I could have it placed wrong or something. If anyone else can spot what I might be doing wrong I'd be very grateful :)

Looping In SQL Server Query

Aug 4, 2010

consider the follwing table, this table actually shows which id was given a new id

i.e 11 was assigned 13

again 13 was assigned 15

15 was reassigned 17....and so on actually 11,13,15,17,19 represent the same user (hope u understood)

customerId rejoiningId

11 13

13 15

15 17

20 21

17 19

48 50

21 25
i need to loop through all the rows and find the relation that which all ids are interlinked

say the user enters the rejoining id -13,hence the result should come out to be as 11,13,15,17,19


if user enters 21result should be 20,21,25

it takes a bit of looping statements in query that i couldnt figure out

Looping Through Nested Recordsets?

Apr 20, 2010

I'm still new to ASP.NET, and I'm trying to rewrite a simple booking/reservation system I did in ASP, but I'm struggling to find an equivalent technique in ASP.NET.

Basically, it a nested recordset. The first recordset returns weeks from a calendar. for each record returned, a basic table row is created, showing the dates & prices then the start of the week is used to query a bookings table to see if there are any bookings for that week. If there are bookings, the <tr> & <td> tags are modified to change to colour & wording to reflect the bookings.

an extract of the code is as follows:

Web Forms :: Looping A Value From A Text Box?

Sep 24, 2010

I have several controls on a web form Dropdown list, text boxes etc. Which are going to be used as part of a stored procedure to enter data in several SQL Tables. One of the boxes is called the number of items now depending on the number inputted here is how many items to be inserted therefore I need to loop so my stored procedure to run again

Not sure if this is relevant or just me confusing myself and making this more complex than it really is but I have several data readers running before I run my stored procedure to help get the data I need for it.

Here is the SQL for it and the answer goes in label1 so then further down when the insert stored procedure runs it checks the value on label1 to run an if statement so I will need this procedure to run as well in the loop.

Looping Through File Directory?

Nov 16, 2010

I have the following values: customerNumber, ProductNumber, PartNumber.There exists a directory structure on a server like follows (the bold italic text is the actual value)://myServerName/Parts/Images/CustomerNumber/ProductNumber/PartNumberSo the part of the file directory that is constant is://myServerName/Parts/Images/but the file structure CustomerNumber/ProductNumber/PartNumber will vary, displaying the actual number valuesEX: //myServerName/Parts/Images/11111/22334/007so I need some code that will loop through the file Directory structure under "Images" and will get the string values of each subdirectory. This will be used to find the image to be used for the specific CustomerNumber, ProductNumber and PartNumber.Does anyone have any good sample code where you have done this before?

ADO.NET :: How To Copy A Datatable Across Servers Without Looping

Dec 27, 2010

i have searched quite a bit on this one and can't seem to find exactly what I am looking for.

I think my first problem is this: How would I bring back a DataTable FOR copying? I know I would need:

Dim dt as Datatable

But then how do I get the Original Datatable in there? I think that once I have that part, I can just make a connection to my new DB inside a copy subroutine (using the .Copy method) and be done with it. That part I have the code pretty much done for, I think.
