c# - 如何将数组的内容写入文本文件？ C#

Question

我正在尝试将数组的内容写入文本文件。我已经创建了文件，将文本框分配给数组(不确定是否正确)。现在我想将数组的内容写入一个文本文件。 streamwriter 部分是我被困在底部的地方。不确定语法。

if ((!File.Exists("scores.txt"))) //Checking if scores.txt exists or not
{
    FileStream fs = File.Create("scores.txt"); //Creates Scores.txt
    fs.Close(); //Closes file stream
}
List<double> scoreArray = new List<double>();
TextBox[] textBoxes = { week1Box, week2Box, week3Box, week4Box, week5Box, week6Box, week7Box, week8Box, week9Box, week10Box, week11Box, week12Box, week13Box };

for (int i = 0; i < textBoxes.Length; i++)
{
    scoreArray.Add(Convert.ToDouble(textBoxes[i].Text));
}
StreamWriter sw = new StreamWriter("scores.txt", true);

你可以这样做:

System.IO.File.WriteAllLines("scores.txt",
    textBoxes.Select(tb => (double.Parse(tb.Text)).ToString()));
