我的桌面上有一个名为FINAL.TXT的文本文件...其中的值是 123456 i想复制使用流阅读器将这些值转换为数组... i写了一段代码......但它给了我错误的值... i已经使用了按钮和列表框... 这里是代码..

I have a text file called FINAL.TXT on my desktop...values in it are 123456 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
