Follow the code:
var result= db.Table.Where(l => l.Field== value).ToList();
var search = "jOãO pAuLo";
result = result.Where(l => l.Example.Contains(search)).ToList();
It only works like this: João Paulo , if that's the case joão Paulo with the smallest j, it does not work anymore.
Any solution?
There are two other alternatives:
1 - Use ToLower or ToUpper :
result = result.Where(l => l.Example.ToLower().Contains(search.ToLower())).ToList();
result = result.Where(l => l.Example.ToUpper().Contains(search.ToUpper())).ToList();
2 - Use regex :
result = result.Where(l => Regex.IsMatch(l.Example, search, RegexOptions.IgnoreCase)).ToList();
I believe the most elegant way to solve this is by using an extension method.
using System;
using System.Collections.Generic;
using System.Linq;
public class Program
{
public static void Main()
{
var list = new List<String>();
list.Add("AAAAAO");
list.Add("BBB");
list = list.Where(x=> x.Contains("bbb", StringComparison.OrdinalIgnoreCase)).ToList();
Console.WriteLine(list.Count().ToString());
}
}
public static class Extensions
{
public static bool Contains(this string str, string strComparacao, StringComparison argumento)
{
return str.IndexOf(strComparacao, argumento) >= 0;
}
}
