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);
//这使列表为空
myList.Clear();
Console.WriteLine("Elements in the list after using Clear() = "+myList.Count);
}
}输出结果
one two three four five six Elements in the list = 6 Elements in the list after using Clear() = 0
