Linq - EF : How to query a Junction table?

I use c#, linq and EF4.

I have two tables in my DataBase represented in my Conceptual Model:

DataBase Tables:

CmsContents
CmsRelatedCo开发者_JS百科ntents (Junction table)

Entity Type:

CmsContent

I have some Navigational Properties:

for CmsContent --> CmsContents --> Return Collection of CmsContent --> from role: CmsContent1 to CmsContent (map ToContentId)
for CmsContent --> CmsContents1 --> Return Collection of CmsContent --> from role: CmsContent to CmsContent1 (map FromContentId)

Data in DataBase for the Junction Table (CmsRelatedContents) is presented:

FromContentId   ToContentId
4               3
5               2

In table CmsContents:

ContentId
2
3
4
5

I need use Linq or EF to retrieve Objects in CmsContent associated in the ToContentId column filtering the Junction table for a specific FromContentId

Do you have an idea how to do it?

Please provide me sample of code. Thanks for your help on this!

EDIT : SOLUTION

// Option A:
           var test = from cnt in context.CmsContents
                       where cnt.CmsContents.Any(t => t.ContentId == contentId)
                       select cnt;

// Option B: 
       var toContents = context.CmsContents.Where(r => r.CmsContents.Any(t => t.ContentId == contentId));

Thanks guys from your support!

Not sure if i understood you correctly but this might be what you need:

dbContext.CmsContent.Where(r => r.CmsContents.Any(t => t.Id = someId))
