C# Distanct

简单一维集合的使用

List<int> ages = new List<int> { 21, 46, 46, 55, 17, 21, 55, 55 };
List<string> names = new List<string> { "wang", "li", "zhang", "li", "wang", "chen", "he", "wang" };

IEnumerable<int> distinctAges = ages.Distinct();
Console.WriteLine("Distinct ages:");
foreach (int age in distinctAges)
{
Console.WriteLine(age);
}

var distinctNames = names.Distinct();
Console.WriteLine("\nDistinct names:");
foreach (string name in distinctNames)
{
Console.WriteLine(name);
}

List<int> ages = new List<int> { 21, 46, 46, 55, 17, 21, 55, 55 };
List<int> disAge = ages.Distinct().ToList(); //除重
foreach (int a in disAge)
Console.WriteLine(a);
