I'm doing a query like this:

    var matches = from m in db.Customers
        where m.Name == key
        select m;

But I don't need m.Name to be exactly equal to key. I need m.Name to be like key.

I can't find how to recreate the SQL query:

    WHERE m.Name LIKE key

I'm using SQL Server 2008 R2.

How to do it?

Thanks.

回答1:

Would something like this work for you.. ?

var matches = from m in db.Customers
    where m.Name.Contains(key)      
    select m;

this should also work I edited my answer

回答2:

var matches = from m in db.Customers     
    where m.Name.StartsWith(key)
    select m;

Make the search and compare whether the string is either lowercase or uppercase to get the best result since C# is case-sensitive.

var matches = from m in db.Customers     
    where m.Name.ToLower().StartsWith(key.ToLower())
    select m;
