C# Distanct List集合

简单一维集合的使用

//实例2个集合
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);
