Question

When searching for a word in the search field I shall be enable to find a word for instance “cookies” by typing “Coo” or “oOk”. what LinQ syntax do I need to create this functionality?

Beside, the functionality should take account to case insensitivity for instance a word named “ComPuTER” should be found by typing the word “MpUT”?

You can use contains:

var query = from t in tbl
            where t.ToUpper().Contains(input.ToUpper())
            select t;

I used ToUpper to ensure that the table and the source are the same case, so that “Coo” will match “cookies”

There’s also a Like method in SQLMethods, but I have not used this…

var query = from t in tbl
            where SqlMethods.Like(t, "%"+input+"%")
            select t;
