Show your entities. It is not clear why property names become filter by x.Key. It is possible to build/transfer any filter dynamically.

| Feb 4, 2022 at 21:35 | comment | added | brk.gs | i have a LanguageTranslate Table in database. Database scheme is Key-Value. Exc. L LanguageId =1 Key=ProductName Value=Water ProductTranslate class is not entity. it is translate content class. But i get only this class properties from database. I don't want to pull unnecessary records from the database where I don't need to use them. I will only pull the key values of the property in this class. there is no problem in this part. however, I wanted to set up such a structure because the query is very complex where I want to bring the contents of the language I want. | |

Side note: Consider whether you need to group the ShortDescription and Description conditions, so a Description match still requires a Productname match. What you have now is: (product-matches && Short-description-matches) || (description-matches).

Welcome to StackOverflow. In order to get a better answer, please provide more details in your question. What is the starting generic type for your IQueryable<>? Is it ProductTranslate? What is the desired output type? Func<ProductTranslate, bool>? Expression<Func<ProductTranslate, bool>>? IQueryable<ProductTranslate>? IQueryable<Dictionary<string, string>>? Func<KeyValuePair<string, string>, bool>?

Well first, for any given x, x.Key will never equal "ProductName", "ShortDescription", and "Description" all at the same time. What type do you expect for x? Is it a dictionary or associative array such that the expression would be something like x => x["ProductName"]=="product1" && x["ShortDescription"].Contains("short desc") || x["Description"].Contains("desc")?
