问题描述

我的桌面上有一个名为FINAL.TXT的文本文件...其中的值是

这里是代码..

I have a text file called FINAL.TXT on my desktop...values in it are

i want to copy these values into an array using stream reader...

i have written a piece of code...but it giving me wrong values...

i have taken a for with button and listbox in it...

here is the code..

button_click event
{

using (FileStream ar1=File.OpenRead(FINAL.TXT))
           {
               using (TextReader ART1 =new  StreamReader(ar1))
               {

                  
                           int i;
                           for (i = 0; i < 6; i++)
                           {
                               array1[i] = Convert.ToInt32(ART1.Read());
                               listBox1.Items.Add(Convert.ToInt32(array1[i]));
                           }
                      

                   
               }
           
           }



}

推荐答案

否则读起来像这样。在这里你可以循环读取一个字符，直到达到EOF。

Otherwise read like this. Here you can read a single character in loop till it reaches EOF.

using (StreamReader reader1 = File.OpenText(@"final.txt"))
    {
        do
        {
             char next = (char)reader1.Read();
             Console.WriteLine(next);
        }
        while(!reader1.EndOfStream);
    }

尝试不同的方法...

Try a different approach...

string theFileContentsAsString = File.ReadAllText("final.txt");
            int[] theStringAsArray = theFileContentsAsString.ToCharArray().Select(c => Convert.ToInt32(c.ToString())).ToArray();
            //bind theStringArray to listbox here
