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，为文件分配了文本框（不确定是否正确）。现在我想将数组的内容写入文本文件。写行者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);

Answer 1

你可以这样做：

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

Answer 2

using (FileStream fs = File.Open("scores.txt"))
{
    StreamWriter sw = new StreamWriter(fs);
    scoreArray.ForEach(r=>sw.WriteLine(r));
}

Answer 3

您可以尝试在关闭文件之前写入文件...在FileStream fs = File.Create("scores.txt");代码行之后。

您可能还想使用using。像这样：

if ((!File.Exists("scores.txt"))) //Checking if scores.txt exists or not
    {
        using (FileStream fs = File.Create("scores.txt")) //Creates Scores.txt
        {
            // Write to the file here!
        }
    }

Answer 4

您可以将<TextView ... android:padding="10dp"/>转换为数组，然后将该数组写入文本文件

List
