Use Linq ToDictionary To Return A Dictionary With Multiple Values In The Dictionary Items?

Jan 25, 2010

I want to group items from a linq query under a header, so that for each header I have a list of objects that match the header title. I assumed the solution would be to use ToDictionary to convert the objects, but this allows only one object per "group" (or dictionary key). I assumed I could create the dictionary of type (String, List Of()), but I can't figure out how to write it. As an example I have written a simplified version below.

Flatten A Dictionary Of Dictionaries And Sum The Values Of The Inner Dictionary With LINQ?

Apr 16, 2012

I have the following object:

countDictionary As Dictionary(of Category, Dictionary(of Date, Integer))

The Class has a Enumeration Property. For the purposes of demonstration, I'll call it MasterCategory.I have been trying to get out an object that looks like the following:

groupedCountDictionary As Dictionary(of MasterCategory, Dictionary(of Date, Integer)

The best result I could get was:

Lookup(of MasterCategory, Dictionary(of Date, Integer))

From:

countDictionary.ToLookup(Function(o) o.Key.MasterCategory, Function(o) o.Value)

Which results in a IEnumerable (Of Dictionary(of Date, Integer)) for each MasterCategory value.However, I need that IEnumerable of Dictionary flattened to one dictionary with all the integers summed (total counts) for each date. I then tried to use various selects and group bys (from numerous stackoverflow posts) to "flatten" it, but my efforts have fallen short.

Current Code

[Category Class]
- MasterCategory As Enum
- Name As String etc

.net - Filter Custom Dictionary With LINQ ToDictionary - "Unable To Cast Object Of Type 'System.Collections.Generic.Dictionary`2"

Jul 7, 2010

I have created a Dictionary class (MyDictionary for the example). I am currently trying to pass MyDictionary into a function, filter it into a new instance of MyDictionary and pass this new instance into another method. When I am attempting to create the second instance from the filtered first instance of MyDictionary via Lambda Expressions and the ToDictionary Method, I am getting the following error:

Unable to cast object of type 'System.Collections.Generic.Dictionary`2[System.Int32,System.String]' to type 'MyDictionary'. I have simplified the example and recreated it in LINQPad and am getting the same error.

Here's the simplified version of my code:

Possible To Rename Few Resources Images?

Jul 21, 2009

I am currently working on a project that contains a few images, that are placed in a lot of different controls. I was wondering, is it possible to rename those few resources images , ex. image1 name is bg, and when i click a button to rename that image to bg2 and rename bg2 to bg.. something similar to an image swap, just done by renaming resources. I will wait for a few suggestion, but if all lead to the same possibility, which I hope is not "no, you can not", than my time is narrowed down for better use, other than changing each control's image manually..

Rename A Collection At Runtime?

Jan 10, 2012

Building a MP3 player fairly large but will upload the zip file if needed. It almost compelted. I am stuck on one thing I want to be able to create a playlist collection based on the name the user enters into a textbox and name the collection with that name if the user enters mysongs as the name the collection would be named mysongs. I know how do declare a new collection but there is no way to change the name to mysongs I am not limited to collections it could be an array or a list of strings my thought here is to save the list of mysongs to a collection to find the list if it already exists and open the list if found to a listbox I know how to go through the list and put results in a listbox. Maybe a collection of collections is not the right way to handle this?
