如何清空 C# 列表?
要清空 C# 列表,请使用 Clear() 方法。
首先,设置一个列表并添加元素 −
List<string> myList = new List<string>() { "one", "two", "three", "four", "five", "six" };
现在,让我们清空列表 −
myList.Clear();
示例
using System; using System.Collections.Generic; public class Program { public static void Main() { List<string> myList = new List<string>() { "one", "two", "three", "four", "five", "six" }; foreach(string str in myList) { Console.WriteLine(str); } Console.WriteLine("Elements in the list = "+myList.Count); // this makes a list empty myList.Clear(); Console.WriteLine("Elements in the list after using Clear() = "+myList.Count); } }
输出
one two three four five six Elements in the list = 6 Elements in the list after using Clear() = 0
