Linq Output Value

Question

This linq below is returning the full Key Value Pair [Key Object] . Can someone help me with the linq to return the Key Value: var items = dict[dictItem.Key].Skip(i).Take(25).ToList(); CORRECT OUT PUT BELOW: [_ColorBlue]]: [{ Color: Blue ColorId: 2 ColorItem: Shirt }] WRONG OUT PUT BELOW: [_ColorBlue System.Collections.Generic.List`1[Pentair.Domain.Client.Helpers.Commands.HistoryItem]]: [{ Color: Blue ColorId: 2 ColorItem: Shirt }]

From the output you provided it seems like you have dictionary of KeyValuePair and ClassObject where your KeyValue pair is of type string List/Ienumerable. So basically you need key from the pair and value from dictionary. try something like below. should be good. Var items = dict.Skip(i).Take(25).Select(x=> new { Key= x.Key.Key ValueAssociated = x.Value }).ToList();

okay. Now I got the issue it can be solved as creating List of dictionary. I am not sure what exactly you are trying to do here but list of dictionary with complex object is sort of bad idea in terms of performance. Replace object with yoru colorItemObject class. List string  object >> listOfDict = new List string  object >>(); var result = dict.Skip(0).Take(1).Select(x => new { Key = x.Key.Key ValueAssociated = new Dictionary string  object >() { { x.Key x.Value } } }).ToList(); result.ForEach(obj => listOfDict.Add( new Dictionary string  object >().Add(obj.Key obj.ValueAssociated))) ;

This is the issue. ColorListMethod intakes an List () Input. Your link returns an IEnumerable type. I cannot sent the IEnumerable type to the ColorListMethod Input because its 2 different types. So how would I convert the IEnumerable to the List () ???

Your output is good but when I want to sent the list of items from your linq in the method below the dictionary input type is different from the linq type Var items = dict.Skip(i).Take(25).Select(x=> new { Key= x.Key.Key ValueAssociated = x.Value }).ToList(); ColorListMethod(items); I get an IEnumerable conversion type error... public ColorListMethod( List>> objectList) { this.ColorLisy= colortList; } // ColorListMethod()

okay to convert your items to json format you can use Json Libraries to serialize the items. So where are you stuck now? Are you doing group by anywhere? Please explain the issue and expected output with example if any.

That works however the next input function only takes List>>(); When I do your logic below it changes it to a Y=IEnumerable if that makes sense. Var items = dict.Skip(i).Take(25).Select(x=> new { Key= x.Key.Key ValueAssociated = x.Value }).ToList(); I actually did this below. However I missing the groupby key value. the out has to be in a json format. var colorList = dict[dictItem.Key].Skip(i).Take(25).Select(x => new { Color= x.color Id = x.colorId Item = x.colorItem }).ToList();
