C# - Create A New Array In While Loop With Each Iteration?
Jul 21, 2010
I've got a while loop that's doing some stuff, and what I want is for it to create a new array each time.
while(condition){
//do some stuff
//create an array x[]
//amend values in array
//save as new array each time until loop finished
}
Actually i need to store the comma separated values of different datatypes in an array using split.And then i hav to sort these values comparing zeroth position element of all rows.

I think this is something really easy that I am missing. I have a loop that is sending emails. The loop adds an attachement from a FileUpload instance. The first run of the loop is fine but each subsequent run the attachment is empty. I have found mention of reseting contentstream.position to 0 but that doesn't seem to apply to the FileUpload control. I am attaching the code below.

I need to build an array of implicit objects in a var object by looping through a List and adding the to the array. For example...
Code:
var data = new[] { new { Name = "China", Value = 1336718015 },
new { Name = "India", Value = 1189172906 },
new { Name = "United States", Value = 313232044 },
new { Name = "Indonesia", Value = 245613043 },
new { Name = "Brazil", Value = 203429773 },};
If I wanted to dynamically add new objects with the Name and Value values above by a looping through an existing List, how would I go about it?

I have to set GridView.DataKeyNames(This is really a question about the syntax for a string array, in VB.Net.)
I am discovering the PrimaryKey columns names from within a loop, ie:
For Each fld As IEntityField In Me.llbDataSource.EntityCollection(0).PrimaryKeyFields 'fld.Name ' this is where the column name is stored, so I have to get this into an array Next I can not use this syntax.
GridView.DataKeyNames = new string() { "PowRatHP", "Voltage", "Phases", "Poles", "Drive" }
So, basically, how does one declare a string array (as required by GridView.DataKeyNames), and then populate the elements of the array from within a loop?

My original code was in classic vb. and could use redim array to resize them. I was porting the code to c# now and lately i have run into an issue to resize a 2 dimensional array. The thing here is I have a 2 dimensional array whose 2nd dimension needs to be increased dynamically as needed to accommodate the data. For say
String[,] ary1=new String[2,10];
I'm doing some operation in a loop and filling in the data in ary1. And if the loop still continues, on reaching the ary1 upper bound i need to increase the size further to accommodate 10 more rows. I tried couple of ways to copy it to a bigger array and assign it back to the current array. but somehow dint work.

My question is, is there any benefit to instantiating a new userDetails object in every loop, or can this be created outside the loop and title, forename and surname just written over with every pass of the loop?

I am currently working on a project where I am trying pull a list of entries from an Oracle database depending on a selection that is made by the user via a Drop Down list. Then I want provide a user with a list of options that they can select that is related to the drop down option that they have selected. For Example:
First Drop Down from database: Honda, BMW, Ford
If user selects:
Honda -- options that are available in the separte table in the database for this entry are -- Type, Engine Size, Colour
BMW -- options that are available in the separte table in the database for this entry are -- Colour, Wheel Trims, Extra's
Ford -- options that are available in the separte table in the database for this entry are -- Extra's
What I wanted to do is have a form displayed to the user where thy can say select a car eg. "BMW" and then on the change of that drop downs index the site will do a call back and retrieve the entries for the BMW options in the seperate tabel, these being Colour, Wheel Trims, Extra's. Then it will put these details in a DataSet and then i wanted to create a new text box or input field for the users to enter details in. I have tried the below code with no success as I get an error on my for loop of looking through the options DataSet.

First I am sorry if I am creating a thread in the wrong category as I am not sure which is the best suitable place for this question: I want to create a user defined data structure, which will be a 2 dimensional array such that each individual square of this 2-dimensional array will also store the score and the grades. ( Iam using VB.NET) More details: for example: There is an 2 dimensional array with 3 columns and 2 rows, I want to fill each of the (0,0);(0,1);(0,2) with their own score (Integer type) and grades (String Type). And this is same for the rest of the squares i.e. (1,0);(1,1);(1,2) and (2,0);(2,1);(2,2) After creating such custom data structure: "CustomArray", I should be able to create the instance of this custom data structure (which will be a class) and code something like this:
Dim objCustomArray as CustomArray
objCustomArray = New CustomArray
for i as Integer =0 to 3
objCustomArray(0,i).SetScore(1)
objCustomArray(0,i).SetGrade("Good")
Next
-------
for i as Integer =0 to 3
Dim myVal as Integer = objCustomArray(0,i).GetScore()
Dim myGrade as String = objCustomArray(0,i).gettGrade()
Next

My brain doesn't seem to be working today. I googled around for this and just couldn't find it, which seems kind of strange since this is such a basic question that I can typically find out very quickly.
I'm trying to create an array of DateTime objects. I can't use a List.
DateTime[] dates
dates[0] = Convert.ToDateTime("12/01/2009");
dates[1] = DateTime.Now;
However, I get an error, stating use of unassigned local variable.

I'm doing some custom code for a SharePoint webpart in C#. Specifically, I'm making a quiz, my main point here addressing the list that holds the question, answer choices, and correct answer.
At the last stage of the quiz I need to check the answers selected by the user against the correct answer in the list. Currently, I'm doing the following to check if each is correct, which I'm assuming isn't very efficient because it iterates through each question. Is there a method, specifically for the SPList foreach loop, that would be more efficient?
// 1. Store questions and answers in class
List<submittedAnswers> answeredQuestions = new List<submittedAnswers>();
// 2. From POST pull answered question IDs and answer IDs (which correspond to the question primary key and answer choice number both stored in the list)
// INSERT BEAUTFIUL AND EFFICIENT WHILE LOOP HERE
// 3. Loop through each question is list, if question was given, test if correct/incorrect
using (SPWeb myWeb = mySite.OpenWeb())
{
SPList answerList = myWeb.Lists[questionList];
foreach (SPListItem quizEntry in answerList.Items)
{
int pullAnswerId = int.Parse(quizEntry["Answer"].ToString()); // Pull answer number from list
int pullQuestionId = int.Parse(quizEntry["ID"].ToString()); // Pull primary key of question
submittedAnswers result = answeredQuestions.Find(delegate(submittedAnswers e) { return e.questionId == int.Parse(quizEntry["ID"].ToString()); });
if (result != null)
{
if (result.responseId != pullAnswerId) // If the response was different from the answer
incorrectAnswers++;
else
correctAnswers++;
}
}
}
// C# quiz grading magic here....

In my app I have a criteria builder section that's built using jquery and is pitched back to the controller in a form post and picked up as IList by the model binder as suggested in Phil's post here: http://haacked.com/archive/2008/10/23/model-binding-to-a-list.aspx A really simple way that I'm persisting the criteria across posts is re-delivering the IList object to the view. I'm using a DisplayFor() template for this object, but because it's a list I need to know the index # inside of the template.

I need to know what would be the best choice of array to use given the following specifications. This array's size will be predermined upon the loading of the appication. All I want to do is be able to add values to this array and replace preexisting array items with new values without the array changing size. Someone suggested that I use a Dictionary Array Object? I would appreciate any suggestions.

I have a webform that gives the user the option to submit 5 referrals. Currently I only have 1 checklistbox that gives the user a choice to select products of interest for all the referrals. I would like to add a checklistbox under each referral input field in case there are different product interest for each referral? So when the referral gets a confirmation email it contains the product of interest that is specific to that referral.
