LINQ is it possible to add where clauses dynamically

Question

I want to search my db with different keys. According to the input, there may be 1 key to 10 keys. Is there a way to add OR/AND clauses to my Linq query dynamically?

Answer 1

You can use the extension methods of LINQ

ctx.Feed.Where(f => {  
//Your logic here
if(something != null){
      return f.Property == something
  } 
}).Select( new { FeedId = feed.DuyuruId,
                    FeedTitle = feed.FeedTitle,
                    FeedContent = feed.FeedContents,
                    FeedAuthor = user.UserName + " " +User.UserSurname })
