C# - Optimize Code - Linq And Foreach Loop 15k Records?

Sep 6, 2010

this is my code


basically, the InstellingGegevens table gest filled in by some procedure from another server.
the thing i then need to do is check if there are new records in this table, and fill in the new ones in Instellingens.

this code runs for like 4 minutes on 15k records. how do I optimize it? or is the only way a Stored Procedure?

this code runs in a timer, running every 6h. IF a stored procedure is best, how to I use that in a timer?

C# - Using A Variable From A Foreach Loop?

Dec 6, 2010

i'd like to be able to check to see if an item with the same id has already been placed in the database, if so to then update the quantity for that item, however due to the fact I have this in a foreach loop it will update the quantity for each item.

When I placed the Command outside of the loop I am unable to use 'ItemID' as it's not in context, is there anyway I can get around this?

foreach (UserItem ItemID in (List<UserItem>)Session["UserSession"])
ConclusionPage.InsertCommand = "IF EXISTS (SELECT ItemID FROM tblUserItems WHERE UserID='@CurrentUser' AND ItemID='@ItemID') UPDATE tblUserItems SET Quantity = Quantity+1 WHERE (UserID = '@CurrentUser') AND (ItemID = '@ItemID')";

C# - Foreach Not Initialing The Loop Variable?

Mar 9, 2010

I'm using a foreach to loop through an IList of objects in a Partial View in ASP.NET MVC.

Here's the entire code (Message is one of my classes from the Model).

<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<IList<Message>>" %>
if (ViewData.Model.Count > 0)
foreach (MvcTest.Models.Message m in ViewData.Model)

ie explicitly declaring a variable for the IList rather than just using the (strongly-typed) Model, and it works fine.

C# - Passing In A Value To A Usercontrol Through A Foreach Loop?

Dec 21, 2010

in my asp.net mark up I have a foreach loop that iterates through a simple list. In this foreach loop I am adding a new user control and attempting to pass in the value from the loop. However, this value just wont budge and get inside that damn control!

<%foreach (userInfo i in this.items)
{ %>
<uc1:ItemControl ID="ItemControl" runat="server" UserID='<%#Eval("userID") %>'/>
<%} %>

userID is a public property in the control, when it goes to set, the value is just literally :

<%#Eval("userID") %>. I've tried #Bind and =Value but nothing seems to work.

DataSource Controls :: LINQ To SQL - Foreach - To CSV?

Jun 11, 2010

I'm close to the solution I see where I am going wrong just unsure how to approach it. I want to be able to take a tables worth of data (via DataClasses) and put it in a CSV to download.

A LINQ to SQL query is performed (basically a 'Select All' from tbl_Newsletter), takes those results and the idea is to feed those results, one by one through the foreach which, inside it, is the CSV's definition e.g. List.Add(etc) as you'll see. After which the CSVExporter method is called - which works, as I can Download it, it just wont display any results.

C#: [Code]....

To which I get: Compiler Error Message: CS1729: 'Newsletter' does not contain a constructor that takes '2' arguments

with Newsletter obj = Newsletter.GetAll(); in place of Newsletter obj = new Newsletter();

I get: Compiler Error Message: CS0029: Cannot implicitly convert type 'System.Collections.Generic.List<Newsletter>' to 'Newsletter'

DataSource Controls :: Loop Through The Records Of A Table?

Mar 19, 2010

im learning t-sql, infact i needed its while-loop to loop through records of a table, i found this code in some book:


i understand here that setting the rowcount variable to 1 will force the select statements to return only one record, do all above select statements return one record only?

if the underlined select statement returns one record everytime it is executed, isn't it supposed to return the same first record of the table everytime? is there a better way to loop through a table's records?

Architecture :: Loop Through Large Collection 100 Records At A Time?

Jan 21, 2011

I am building a small mass email application for my department. Which basically emails out a notice to a large list of email addresses. Because the company email server limits the amount of email addresses that can be contained in a single email I have to break the list apart into smaller 100 email groups.

I've create the query to pull all email addresses needed, stuffed them into a collection but I am not sure how to grab 100 emails at a time and send it off to another sub to perform the email send before grabbing the next 100.

This is what I have so far.

using sql server 2005.

i need to query a table which normally will return multiple records for the id and I need to loop through probably using a cursor and pull values out from each record to make a string.

what is the syntax for this? i've seen cursors using a set number (EX: loop through 5 times) but I need to create a query so that I can loop through once for each row returned from my query.
