Linq查询过滤结果

Question

I'm not super familiar with LINQ. Here's some code:

if (!String.IsNullOrEmpty(searchString))
            {
                games = games.Where(x => x.Name.Contains(searchString));
            }

Works as it should; however, what I'd like, rather than filtering results based on whatever text the user inputs, if the user inputs say "L" is there a way within the LINQ query to have it filter through the 1st letters of x.Name verses any x.Name that contains the letter.

IE say I have...

League_of_Legends
LOTRO_
Dota_2
Call_of_Duty_4
Final_Fantasy_7

And the user inputs "L" rather than returning all but Dota 2 , can it return only League of Legends and LOTRO as they are the only two who's names actually start with "L".

I'm assuming its something along the lines of... games = games.Where(x => x.Name.Contains<***something***>(searchString));

Thanks!

Answer 1

I assume you're looking for StartsWith . Note that this will work for any prefix, not just a single letter.

games = games.Where(x => x.Name.StartsWith(searchString));

If you want a case-insensitive search (eg where lowercase l matches League_of_Legends too), use:

games = games.Where(x => x.Name.StartsWith(searchString, StringComparison.CurrentCultureIgnoreCase));
