List<string> IDs = new List<string>();
XDocument doc = XDocument.Parse(xmlFile);
var query = from c in doc.Root.Elements("a").Elements("b")
select new { ID = c.Element("val").Value};
How can I convert query to List without loop foreach ?
foreach (GridViewRow row in gridView.Rows)
{ // Access the CheckBox
CheckBox cb = (CheckBox)row.FindControl("SuburbSelector");[code]....
I tried the following and got error
Linq:
var Str = SuburbGridView.Rows.Cast<GridViewRow>().Where(r=>(CheckBox)r.FindControl("SuburbSelector")==checked);
Error:

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')";
ConclusionPage.Insert();
}
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)
{
Response.Write(m.RenderHtml());
}
}
ie explicitly declaring a variable for the IList rather than just using the (strongly-typed) Model, and it works fine.
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.

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?

Each time the user is moving to a new page, I am updating the session with the new page he is right now.

Im using visual web delveloper 2010 express and im using the MVC template project.Ive basically got a news table in MSSQL Express, in there are these fields ID,(Title,Body,PostedOn,PostedBy) all i wanna do is loop through them to put them on the view.Im after a nudge in the right direction, I want to be able to do a SQL lookup in the controller put that data in a DataTable then run a foreach loop on the table to display this on the view. The problem im getting is I know youre not suppsed to put any HTML in the controller and I cant pass the datatable to the view to do the loop in the view.. so where/how do I do the loop.

I would like to get the list of users (from db) who meets my SQL select statement, and send email for each of them.my current looks like this
Code:
Dim constguser As New SqlConnection

Dim email1D, email2D, userNickName, userName, rc As String

If i run this code its only going to get the name and email of the first result found. I was wondering if there is a faster way to get all user result from the sql query, myb using a for loop?

I have one Listbox and a List of data

I want to loop thru dropdown list and check the individual list item text using C#, let me know what is the best way to do this?
View 4 RepliesI am trying to assign values I've gathered from a JSON feed to my own type, a class in which I have defined certain fields (properties) to put the JSON elements into, plus elements that are derived from a RegEx pattern matching process. This will then allow me to access the object using LINQ, as I am using a List to hold my objects. There is a foreach loop in my code that loops for each match that my RegEx method finds. I am only interested in the parts of the JSON feed where there is a match. So my own defined class is as such:
//simple field definition class
public class TwitterCollection
{
public string origURL { get; set; }
public string txtDesc { get; set; }
public string imgURL { get; set; }
public string userName { get; set; }
public string createdAt { get; set; }
}
And then I want to populate List in the RegEx Matches loop:
foreach (Match match in matches)
{
GroupCollection groups = match.Groups;
var tc = new List<TwitterCollection>()
{
origURL = groups[0].Value.ToString(),
txtDesc = res.text,
imgUrl = res.profile_image_url,
userName = res.from_user_id,
createdAt = res.created_at,
};
}
The code will then go on to extract and sort the results via Linq to Objects. But compiler won't actually let me create my var tc = new List<TwitterCollection>() because: 'System.Collections.Generic.List' does not contain a definition for 'origURL' ... even though I have defined it. It does not flag an error if I simply write new TwitterCollection but then how do I refer to this in my Linq expression later on??
I have dropdown list I want to use the arror to click and control and select the value in the dropdown box , the first click select item1 .... How can I do that?
