I have a CSV File with Raw Data which I'm trying to match with multiple files, while sorting I need to match account codes to their accounts.
I'm using a List
of Account
and using StartsWith
to try and match:
using System;
using System.Linq;
using System.Collections.Generic;
public class Program
{
public static void Main()
{
var accounts = new List<Account> {
new Account {
Id = 9,
Code = "5-4",
Name = "Software",
},
new Account {
Id = 10,
Code = "5-4010",
Name = "Hardware"
}
};
var hardwareAccount = accounts.FirstOrDefault(x => "5-4010".StartsWith(x.Code));
Console.WriteLine(hardwareAccount.Name); // Prints Software - Should be Hardware
var softwareAccount = accounts.FirstOrDefault(x => "5-4020".StartsWith(x.Code));
Console.WriteLine(softwareAccount.Name); // Prints Software - Correct
}
}
public class Account {
public int Id { get; set; }
public string Code { get; set; }
public string Name { get; set; }
}
They are obviously matching the first Account
, is there a way to make it match in order?
Updated Solution:
Thanks @SirRufo
class Program
{
static void Main(string[] args)
{
var accounts = new List<Account>
{
new Account
{
Id = 9,
Code = "5-4",
Name = "Software",
},
new Account
{
Id = 10,
Code = "5-4010",
Name = "Hardware"
}
}.OrderBy(x => x.Code.Length);
var hardwareAccount = accounts.LastOrDefault(x => "5-4010".StartsWith(x.Code));
Console.WriteLine(hardwareAccount.Name);
var softwareAccount = accounts.LastOrDefault(x => "5-4020".StartsWith(x.Code));
Console.WriteLine(softwareAccount.Name);
Console.ReadKey();
}
}
public class Account
{
public int Id { get; set; }
public string Code { get; set; }
public string Name { get; set; }
}
You have to order all matches by the code length
accounts
.Where(x => "5-4010".StartsWith(x.Code))
.OrderBy(x => x.Code.Length)
.LastOrDefault();
