如何在 C# 中從包含空字串的清單中移除一個空字串?
首先,設定一個包含空字串的列表作為元素。
List<string> myList = new List<string>() {
" ",
" ",
" "
};現在讓我們使用索引移除一個空元素。
myList.RemoveAt(0);
示例
using System;
using System.Collections.Generic;
using System.Linq;
class Program {
static void Main() {
List<string> myList = new List<string>() {
" ",
" ",
" "
};
Console.Write("Initial list with empty strings...
");
foreach (string list in myList) {
Console.WriteLine(list);
}
Console.Write("Removing an empty element from the list...
");
myList.RemoveAt(0);
foreach (string list in myList) {
Console.WriteLine(list);
}
Console.WriteLine("Empty List after deleting an empty element is shown above...");
}
}輸出
Initial list with empty strings... Removing an empty element from the list... Empty List after deleting an empty element is shown above...
