How To Convert List Into Ienumerable

May 1, 2010

I am using LINQ for data connectivity and have made class which return me the result set into presentation here is the syntax:-

public List<ClsDermaInvestigation> MthdisplayInvestigation()
List<ClsDermaInvestigation> lstinvst = new List<ClsDermaInvestigation>();
ISingleResult<USP_Patient_Dermatology_InvestigationResult> investresult = objderma.USP_Patient_Dermatology_Investigation(PatientID, RepDate, Hb, TLC, F);
foreach(USP_Patient_Dermatology_InvestigationResult rel in investresult)
ClsDermaInvestigation objinvest = new ClsDermaInvestigation();
objinvest.Albumin = Convert.ToDouble(rel.Albumin);
objinvest.ALP = rel.ALP;
objinvest.ANA = rel.ANA;
objinvest.Date =;
lstinvest.add(objinvest)}return lstinvest}
This list is returning me the result.It works fine but in 1 case am using the same list to bind my Date dropdownlist.
//aspx.cs code
List<Dermatology.ClsDermaInvestigation> objlstinvest = objinvest.MthdisplayInvestigation();
//Array s =
drpDate.DataSource = s;
drpDate.DataTextField = "Repdate";
drpDate.DataValueField = "Repdate";

But it throws an error that list does not conatin a property with "Repdate";. How can i bind this list with dropdownlist?? Can i convert it into some type so that i would be able to bind it??

IEnumerable - Get The Split String Into OpensReviews List

Sep 24, 2010

I have a string which is stored as a cookie. The string is made up of the following data:

int userId
DateTime expiryDate

A user can have a number of these, so I store them like this "userId,expiryDate$userId,expiryDate"

When I retrieve the cookie value, I then split the string and add it to a list. The list is List<OpenReviews> openReviews, which contains the two variables above. I use the following piece of code to split the string:

string[][] reviews = value.Split( '$' ).Select( f => f.Split( ',' ) ).ToArray();

As you can see it goes to an array which I then have to iterate through to add it back into my list. All of which seems extremely long winded. I believe I can use the code above to put it into an IEnumerable<IEnumerable<string>> format. The problem is I don't know how to then get it into my List<OpenReviews> I'm therefore looking at getting the split string into my OpensReviews list as efficiently as possible.

Using The IEnumerable Function Intersect() To Combine A Few List And Get The Similar Integers?

Jun 2, 2010

I would like to use the IEnumerable function Intersect() to combine a few list and get the similar integers from each list. The problem I'm faced with is that I don't know how many list I will need to compare.

Here is an example:


results = A.Intersect(B).Intersect(C)

This works great, but the next time around I may have a D{1,2} next time I come across the function.

I'd like to use the Intersect method, but I'm open to new ideas as well.

ADO.NET ::Convert Dataset Into List

Nov 10, 2010

I am developing a website using Visual Studio 2010, SQL server 2008 and WCF. Already i have developed DAL (Data Access Layer), for some of pages i want to use WCF services and Silverlight, I am new for WCF and i understand that all should be done in List<> for Silverlight and WCF. But all my methods in DAL will return the records in DATA SET format, So my ultimate aim is to convert the DATA SET into List. I browsed in internet and got many explanation like serialization , IEnumarable and so.... but i have 1000 of methods in my DAL, so for the each method i do not want DATA SET to LIST convertion. So i am thinking of having one common class the responsibility of comman class will be get the dataset and return the List [Convert DATA SET to LIST ] For example(Just Psedo explanation for undertanding, Ignore the Syntax error )

Public List< > DsTOLi(dsRecord)
// Here we will convert DATA SET to LIST
return liRecord;

Web Forms :: Error Adding Item To List Box When Trying To Convert From VB.Net Code

Feb 24, 2010

I inherited an application written for VB.Net and am converting it over to ASP.Net, with VB as the back end. I have a data pull that adds values to a new instance of a class, then adds the item to a listbox. It worked great in the VB.Net version, but I get the following error in the Visual Studio Text Editor when I try to use the code:

Overload resolution failed because no accessible 'Add' can be called with these arguments:

'Public Sub Add(Item As System.Web.UI.WebControls.ListItem)':Value of type 'MyItem' cannot be converted to System.Web.UI.WebControls.ListItem'.
'Public Sub Add(Item as String)':Value of type 'MyItem' cannot be converted to String.

I have played around with the code quite a bit and have been researching online, but I'm just drawing a blank here.

I put the class("MyItem") in the "App_Code" folder in a file called "MyItem.vb". The class code is as follows:


The code I have for the sub that is supposed to add the items to the listbox is as follows:
