.net - Check Keyvaluepair Againt Existing Values In List Of Keyvaluepair
Aug 22, 2010How can I check a new KeyValuePair against an existing list of KeyValuePair ? I want to compare for a condition to include or exclude the item. I am using vb.net 3.5
it is a nested For loop and I am deleting a datarow on the result of the condition
args = (existing list of KeyValuePAir)
For Each datarow As DataRow In ds.Tables(0).Rows
Dim args2 As KeyValuePair(Of Integer, Integer) = New KeyValuePair(Of Integer, Integer)(datarow.Item("Integer1"), datarow.Item("Integer2"))
what I want to do here is see if args2 is already contained in args if not I would delete the datarow , but I also need to search the datarow multiple times
SortedList Vs. SortedList(of TKey, TValue)
Jul 9, 20091) SortedLIst has a GetKey property: you ask for the nth key in the sorted list of keys and you get it. SortedList(of TKey, TValue) does not have this kind of feature. Why not?
2) SortedList stores values as "object." Is this a less memory-effective method to store values of Double than SortedList(of TKey, TValue)?

Cycle Through A Sortedlist?
Oct 28, 2011Here's a list example
SortedList name = test
"nothing" | 0
"something" | 1
How can I go about running a for each loop or something to add each first column in test to, say a listbox.
Listbox should just have listed.
nothing
something
I tried
For Each i In text.Values
lbTest.Items.Add(i)
Next
But that produces:
0

SortedList Not Sorting On Key?
Mar 24, 2009I have a the need for key value pair that I wish to sort so I decided to use a SortedList instead of a HashTable.I am adding the data in the order below to my SortedList which is the order I need it in
Key | Value
--------------------------------
1 "700-800" | List(Of Object)
2 "900-1000" | List(Of Object)
[code]....
The key is a string and the value is a List of objects. The key is representing a time slot that has been concatenated from two integer values and delimited by "-". "700" as a string was 0700 initially an integer.e.g.
Dim key As String = slotTimeStart.ToString() & "-" & slotTimeEnd.ToString()
But once these key value pairs are added to the SortedList they appear in the order
3 "1100-1200" | List(Of Object)
4 "1700-1800" | List(Of Object)
[code]....
Unfortunately I recieve the times slots as two integer values which cannot be changed.Is there any way to force a sort on a SortedList? or is this problem because of the way I am storing my key? Is there a better way to store it?

What Is The Most Efficient Method For Looping Through A SortedList In VB 2008
Oct 29, 2009The code below shows me (I think) that the "for each" loop is about 10% faster than the "i to n" loop, but the "for each" loop creates 567k in new memory? Is this right? Which way is generally most efficient with regards to speed and memory usage? If you want to run this code in VB just add a button and 2 labels to a form.

View 2 RepliesExtract Xml Into SQL?
Jul 29, 2010I have a slightly more complex xml document that I don't believe or know how to extract the info that I need. From what I can tel by the GetElementbyTagName it is only good for grabbing 1 tag, with this one I need to grab the day which only appears once, the attribute of the PricingNodeHourly (hour) and then the LMP. I believe that if all I had to grab was the LMP I would have no issue using the GetElementbyTagName, however I don't believe this is the case. Perhaps I'm wrong.
