从c＃中的文本文件中读取整数并将它们写入数组

Question

I'm trying to read the values of pixels from text file and generate an image file. But first I want to make sure that I can read all of the values in the file. I use this code, but the output misses some of the integers from the input file-the last ones. I don't know why! Can you help me? Here's the code:

namespace txtToImg
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
            TextWriter tw = new StreamWriter("D:\\out.txt");
            string fileContent = File.ReadAllText("D:\\in.txt");

            string[] integerStrings = fileContent.Split(new char[] { ' ' }, StringSplitOptions.RemoveEmptyEntries);

            int[] integers = new int[integerStrings.Length];
            //tw.Write(integerStrings.Length);

            for (int n = 0; n < integerStrings.Length; n++)
            {
                integers[n] = int.Parse(integerStrings[n]);

                tw.Write(integers[n]+" ");


            }
        }
    }
}

I agree with Andrew's comment your streamWriter object isn't getting closed so for one thing I would try this. I made the change below and attempted what you are doing and my output file contained all the entries.

 using (TextWriter tw = new StreamWriter(@"D:\out.txt"))
        {
            string fileContent = File.ReadAllText(@"D:\in.txt");

            string[] integerStrings = fileContent.Split(new char[] { ' ' }, StringSplitOptions.RemoveEmptyEntries);

            int[] integers = new int[integerStrings.Length];

            for (int n = 0; n < integerStrings.Length; n++)
            {
                integers[n] = int.Parse(integerStrings[n]);
                tw.Write(integers[n] + " ");
            }
        }

是的，我刚刚运行它，因为我怀疑你的循环后需要以下内容：

tw.Close();
