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
