在C#中使用Linq拆分具有不同条件的字符串

using System;
using System.Linq;

class Program
{
    static void Main()
    {
        string input = "apple,banana,carrot,grape,orange";
        
        // 使用逗号分隔字符串，并根据条件拆分
        var result = input.Split(',')
            .Select(item => new { Value = item, IsFruit = item.StartsWith("a") })
            .GroupBy(item => item.IsFruit)
            .ToDictionary(group => group.Key, group => group.Select(item => item.Value).ToList());
        
        // 输出结果
        Console.WriteLine("水果:");
        foreach (var fruit in result[true])
        {
            Console.WriteLine(fruit);
        }
        
        Console.WriteLine("蔬菜:");
        foreach (var vegetable in result[false])
        {
            Console.WriteLine(vegetable);
        }
    }
}
