如何将分隔的字符串 split() 为 List<String> [英] How to split() a delimited string to a List&lt;String&gt;

问题描述

我有这个代码:

    String[] lineElements;       
    . . .
    try
    {
        using (StreamReader sr = new StreamReader("TestFile.txt"))
        {
            String line;
            while ((line = sr.ReadLine()) != null)
            {
                lineElements = line.Split(',');
                . . .

但后来想我也许应该用 List 代替.但是这段代码:

but then thought I should maybe go with a List instead. But this code:

    List<String> listStrLineElements;
    . . .
    try
    {
        using (StreamReader sr = new StreamReader("TestFile.txt"))
        {
            String line;
            while ((line = sr.ReadLine()) != null)
            {
                listStrLineElements = line.Split(',');
. . .

...给我，不能将类型‘string[]’隐式转换为‘System.Collections.Generic.List’"

推荐答案

string.Split() 返回一个数组 - 您可以使用 ToList() 将其转换为列表>:

string.Split() returns an array - you can convert it to a list using ToList():

listStrLineElements = line.Split(',').ToList();

注意需要导入System.Linq才能访问.ToList()函数.

Note that you need to import System.Linq to access the .ToList() function.
