Solution 1

try something like this

C#

var q = from item in listItems where item.Contains("id") select item;

or a shorter version

C#

var q = itemsList.Where((item) => item.Contains("id"));

This assumes that id is a string value. To give a proper example you should state the class of item in the list as well as the property you wish to check.

Hope that it will work, but my situation is different, I have table not list, Where the id in the table must be present in the list item,
img id is my list having int values.
The linq code is as under
var db = new CarDataContext();
var deleteImages = from deletimg in db.tbl_Car_Images where imgId.Contains(delete.Car_Id) select deletimg;
