是否可以将字符串数组列表写入txt文件？

这是我的代码，我不知道如何做最后一步。我根据用户输入的数字制作了一个列表I foreach，并且它正确地返回了所有值，但我似乎无法将所有数据保存到txt文件。 / p>

 static void Main(string[] args)
    {
        Console.WriteLine("Unesi broj:");

        int userNumber = Convert.ToInt32(Console.ReadLine());

        var numberLIst = Enumerable.Range(1,userNumber).ToList();

        string path = @"C:\Users\mcrnic\Desktop\scriptFolder\input.txt";

        List<string[]> listaStringova = new List<string[]>();

        int n = 0;

        foreach (var data in numberLIst)
        {             

            n++;

            #region Varijable
            var textBoxNumberRangeFirst = "tbxNumberRangeFirstInput" + data;
            var textBoxNumberRangeSecond = "tbxNumberRangeSecondInput" + data;
            var textBoxNumberRangeThird = "tbxNumberRangeThirdInput" + data;
            var textBoxHomeNumbersFirst = "tbxRangeOfHomeNumbersFirstInput" + data;
            var textBoxHomeNumbersSecond = "tbxRangeOfHomeNumbersSecondInput" + data;
            var textBoxVPNFirst = "tbxRangeOfShortVPNNumbersFirstInput" + data;
            var textBoxVPNSecond = "tbxRangeOfShortVPNNumbersSecondInput" + data;
            var checkBoxNumberTransfer = "cbxNumberTransfer" + data;
            var checkBoxSecretNumber = "cbxSecretNumber" + data;
            var checkBoxSearchByNumber = "cbxSearchByNumber" + data;
            var checkBoxZ1 = "cbxZ1_" + data;
            var checkBoxZ2 = "cbxZ2_" + data;
            var checkBoxZ3 = "cbxZ3_" + data;
            var checkBoxZ4 = "cbxZ4_" + data;
            var checkBoxZ5 = "cbxZ5_" + data;
            var checkBoxZ6 = "cbxZ6_" + data;

            listaStringova.Add(htmlLinije);                
        }


        System.IO.File.WriteAllLines(path, listaStringova);

    }

当我尝试WriteAllLines时，我收到此错误：

错误CS1503参数2：无法从System.Collections.Generic.List转换为string []

Answer 1

WriteAllLines期望一个字符串数组作为第二个参数。您正在发送一个字符串数组数组，因此您需要先将此列表展平。

这可以使用SelectMany完成，如下所示：

var stringlist = listaStringova.SelectMany(line => line);
System.IO.File.WriteAllLines(path, stringlist);

Answer 2

您正在尝试将字符串数组列表写入该文件。您必须编写一个字符串列表（每行一个字符串）：

List<string> listStringova = new List<string>();

Answer 3

您正在尝试为List创建WriteAllLines，而不是字符串[]。根据MSDN，WriteAllLines的唯一重载需要IEnumerable<String>，而不是IEnumerable<String[]>。此外，您应该正确使用StringBuilder类，然后执行WriteAllText。这对你有很大的帮助。

Answer 4

更改此行：

List<string[]> listaStringova = new List<string[]>();

要：

List<string> listaStringova = new List<string>();

这就是你如何声明一个字符串列表。然后改变这个：

listaStringova.Add(htmlLinije);

要：

listaStringova.AddRange(htmlLinije);

这就是如何将数组的所有项目添加到列表中。

Answer 5

您只需使用以下一行代码：

System.IO.File.WriteAllLines(path, listaStringova.SelectMany(i => i));
