无法将文本框文本转换为列表 - WPF

Question

我正在尝试将 textBox.text 转换为列表，它给了我一个错误说 CS0029 无法将类型 'System.Collections.Generic.List' 隐式转换为 'System.Collections.Generic.List'

主要Class:

using System;
using System.Collections.Generic;
using System.IO;

using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Controls;

using System.Windows.Shapes;

namespace Making_A_Language
{
    /// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow: Window
    {
        string filePath = @"D:\programs\Csharp\Making_A_Language\Making_A_Language\Code\Main.fysn";
        List<string> lines = new List<string>();
        List<string> TxtLines = new List<string>();
        string text;

        public MainWindow()
        {
            InitializeComponent();
            lines = File.ReadAllLines(filePath).ToList();

        }

        private void Btn_Save_Click(object sender, RoutedEventArgs e)
        {
            text = TxtBox_Code.Text;
            TxtLines = text.ToList(); // <-- error is thrown here
            foreach (String txtLine in TxtLines)
            {

            }
        }
    }
}

Xaml:

    </Grid>
</Window>

我在 TxtLines = text.ToList(); 收到错误 XAML 中的按钮有自定义样式，如果您需要 App.xaml，请告诉我，如果您需要更多上下文，请告诉我。提前致谢:)

Answer 1

您似乎正在尝试将 TextBox 中的多行字符串转换为字符串列表。你在做什么不起作用，因为 ToList() 方法作为 String class 的扩展会给你字符串中的字符。在这种情况下，字符串实际上是一个 IEnumerable。请参阅以下代码的输出。

public static void Main()
    {
        string x="abcd";
        List <char> myChars = x.ToList();
        foreach (char c in myChars)
        {
            Console.WriteLine(c);
        }

    }
/*output
a
b
c
d
*/

如果我是对的，并且您的 TextBox 中确实有换行符，那么您要做的只是使用换行符作为分隔符来拆分字符串。

string [] myStrings = textBox.Text.Split('\n');
foreach (string str in myStrings) { /*do stuff here*/}

Answer 2

你可以轻松使用.Split

解决方案：

TxtLines.AddRange(TxtBox_Code.Text.Replace("\r", "").Split('\n'));
