Pivot and Unpivot in LINQ Core - linq

Question

I am new to LINQ core. I want to write a query in LINQ Core for doing PIVOT and UNPIVOT on table. I have written SQL query for it but need help in converting to LINQ query. I have searched few articles but it didnt helped.
Below is my SQL Query for PIVOT and UNPIVOT which I need to convert to LINQ Query:
SELECT ResourceName,
max(ENText)as ENText,
max(FRText)as FRText,
max(ZHText)as ZHText,
max(DEText)as DEText,
max(ITText)as ITText,
max(JAText)as JAText,
max(PTText)as PTText,
max([PT-BRText]) as [PT-BRText],
max(RUText) as RUText,
max(ESText) as ESText,
max(SVText) as SVText into #temp FROM
GenericLanguageTranslation
PIVOT
(
max(Translation) FOR LanguageID IN (
ENText,
ZHText,
FRText,
DEText,
ITText,
JAText,
PTText,
[PT-BRText],
RUText,
ESText,
SVText)
) AS Tab2
group by ResourceName
order by 1
SELECT NEWID() as Id,ResourceName, [LanguageID],[Translation]-- into #GenericLanguageTranslation
FROM #temp
UNPIVOT
(
[Translation]
FOR [LanguageID] IN
(
ENText,
ZHText,
FRText,
DEText,
ITText,
JAText,
PTText,
[PT-BRText],
RUText,
ESText,
SVText
)
) AS UnpivotTranslation
Can any one help me in this?

Answer 1

I am able to get PIVOT for the above query using below LINQ :
var languageTranslation = await _genericlanguageTranslationService.GetAllLanguageTranslation();
var query = languageTranslation.GroupBy(c => c.ResourceName)
.Select((g, i) => new
{
ResourceName = g.Key,
RowNumber = i + 1,
ENText = g.Where(c => c.LanguageId == "ENText").Max(c => c.Translation),
FRText = g.Where(c => c.LanguageId == "FRText").Max(c => c.Translation),
ZHText = g.Where(c => c.LanguageId == "ZHText").Max(c => c.Translation),
DEText = g.Where(c => c.LanguageId == "DEText").Max(c => c.Translation),
ITText = g.Where(c => c.LanguageId == "ITText").Max(c => c.Translation),
JAText = g.Where(c => c.LanguageId == "JAText").Max(c => c.Translation),
PTText = g.Where(c => c.LanguageId == "PTText").Max(c => c.Translation),
PT_BRText = g.Where(c => c.LanguageId == "PT-BRText").Max(c => c.Translation),
RUText = g.Where(c => c.LanguageId == "RUText").Max(c => c.Translation),
ESText = g.Where(c => c.LanguageId == "ESText").Max(c => c.Translation),
SVText = g.Where(c => c.LanguageId == "SVText").Max(c => c.Translation)
})
.AsEnumerable()
.OrderBy(x => x.ResourceName);
But I also need to find a way to UNPIVOT.
