I need to search a query based on what the user chooses on dropdowns.

Manoj S

Guys, I have an application in .Net where I need to search a query based on what the user chooses on dropdowns. There are 8 choices, A user can choose to select one, or even all of them, and get the records based on the selection. If I Use if conditions then I would end up with quite a number of IFs which I think is not Ideal, What do you guys recommend?

Hello Manoj,

If the drop down only determines which keyword to is in the query, you might use a dictionaty mapping selection value to a keyword to search.

Even if the entire query is different per selected value, so the dictionary can map each value to the appropriate query that also covers open close principle.
When need to add new.value, you just add additional line to the dictionary, without modifying the code logic
