How Can I Perform Wildcard Searches in LINQ?

Wildcard search in LINQ

LINQ provides a variety of search operators, including Contains, StartsWith and EndsWith. However, if you wish to perform a wildcard search similar to "%Test if%it work%", you need to use the SqlMethods.Like() method.

Usage of SqlMethods.Like() method

The SqlMethods.Like() method allows you to use SQL wildcards to perform fuzzy searches in LINQ queries. Wildcard characters are as follows:

• %: matches zero or more characters.
• _: Matches a single character.

An example of using the SqlMethods.Like() method is as follows:

var results =
    from u in users
    where SqlMethods.Like(u.FirstName, "%John%")
    select u;

This query will return all users whose FirstName column contains the "John" substring.
