ADO.NET :: Remove Data From ArrayList With Linq?
Sep 9, 2010This arrayList produced by the Linq query returns data pairs of an ID and count. I would like to keep pairs that have a high enough count. For example, keep all that have a count of 5 and higher so if the arraylist contains:
userID Count
1 10
2 9
3 9
4 3
5 1
the remaining data in the arraylist would be userId 1,2, and 3 (with their counts). How can I do this?

Nov 24, 2010I have a collection of objects that I want to use LINQ in order to filter out only objects that have properties that meet a certain criteria. I am not big on LINQ so I am not sure how to do this.
I create a basic LINQ statement and get the records this way
Dim lr As IEnumerable(Of LogRecord) = From rr In _logRecords where rr.username="something"
but I only want to add that where condition if someone actually filled in a textbox.
I have other conditions to do the same thing with.

ADO.NET :: Order By A Field In Dictionary Using Linq Expression?
Aug 16, 2010I have an Entity class which has a Dictionary of fields called Data. Now I want to sort Entities by a field in Data. I was able to verify the Linq expression for using fields in a dictionary as e.Data["UserId"] as this seemed to work perfectly when I used LINQ to Objects. e.g. Entities.OrderBy(e => e.Data["UserId"])
However this same expression does not generate the correct NHibernate criteria and errors out finally with a NullReferenceException for propertyName at Hibernate.Loader.Criteria.CriteriaQueryTranslator.GetEntityName(ICriteria subcriteria, String propertyName)in CriteriaQueryTranslator.cs: line 541.
On debugging through NHibernate code, I figured that NHibernate.Linq.Visitors.MemberNameVisitor.GetMemberName(ICriteria rootCriteria, Expression expr) returns a null string in place of the field name after visiting expr using its visitor. This seems to be the cause of grief. I am using an older version of NHibernate (2.1). Are there any limitations in the NHibernate Linq visitor I should be aware of?

C# - Order Datatable By Relevance Using Linq By Column Values Which Are Comma Sperated?
Aug 31, 2010I have a Datatable that contains a column called Tags, Tags can have values such as
row[0] = Tag1
row[1] = Tag1, Tag2
row[2] = Tag2, Tag3
row[3] = Tag1, Tag2, Tag3
row[4] = Tag4, Tag6
and are seperated by comma's etc..
I have the value of Tags for the current document and have run a query to select all other documents that have either of the Tags in there row. for example lets say the current document Tags are (Tag1, Tag2, Tag3)
so from the example rows above all the rows above are returned apart from row[4] Here is the bit i'm lost with, i now want to sort the datatable by how many tags are matched with the current document. so for the example i've talked about so far they should be ordered
row[3] = Tag1, Tag2, Tag3
row[1] = Tag1, Tag2
row[2] = Tag2, Tag3
row[0] = Tag1
Not used linq before but was told it could do this. so far i have
var query = from c in dt.AsEnumerable()
orderby c.Field<string>("Tags").CompareTo(dr["Tags"]) ascending
select c;
MVC :: Create A DraftResult Class In Order To Show Data That Resides In Two Different Tables Using Linq
Aug 9, 2010The problem is I had to create a draftResult class in order to show data that resides in two different tables using linq which means if i want to add or remove a column i will need to do so in the draftresult and in my linq. Here's what my setup looks like: I have two tables (draft, lookUpStatus)
draft table columns
idname,status id
lookupStatus
idtitle
public class draftResult {
public string draftName {get; set;}
public string status {get; set;}
}
I want to list the draft name and the status title in a table view. In order to do this, I wrote the following linq in a method in my sqlRepository class and return it to a IQueryable<draftResult>. My controller instanstiates the sqlRepository object and invokes GetDraftListing().
public class sqlRepository {
private Table<Draft> _draft;
private Table<LookUpStatus> _lookupubStatus;
public IQueryable<draftResult> GetDrafLtisting() {
return (from draft in _draft
join status in _lookuptatus
on draft.StatusID equals status.ID
select new draftResult
{
draftName = draft.name,
status = status.Title
});
}
}
The above process works but does not seem as flexible and i'm trying to get a better understanding of MVC and LINQ.

Access :: UpdateParameters - Form Order - UpdateCommand Order?
Apr 24, 2010From my testing, it appears that the order of parameters for the UpdateParameters must match both the order of the bound fields on the form (asp:Formview), and the order of the parameters in the UpdateCommand. Is that correct? If so, why do the parameters have names if all that matters is the order? I tried both asp:ControlParameter and asp:Parameter. Maybe the more relevant question is why aren't the names used instead of the order, particularly for the form order?
So, given I display the Identity field (CID), and need that for the update, I cannot get the update to work without including it in the UpdateCommand. Of course, since it is an autonumber field in Access, I cannot actually set it. So, I had to add another field to the db (lngUpdateCID) that I could set. That can't be how it has to be done, but I could not figure out another way to do this.
The relevant code is below:

2 Dimensional ArrayList In VB.NET?
Jun 16, 2010I am looping through a dataset and I would like to have the following in this array list
name, from, to, price
john, 40, 50, 39.99

Once I do that, or if it is possible to do it using the dataset that will work with me. But I want to do...

So in my code I wanted to make it easy for me and instead of memorizing the row #, I would just do.. arraylist.row("john").item("from")
