推荐答案

周围有很多教程.例如，参见如何:读取和写入文本文件" [

There are a lot of tutorials around. See, for instance "How To: Reading and Writing Text Files"[^].

U可以使用名称Space正在使用system.IO
然后使用此代码

U can use name Space Using system.IO
then use this code

//This code is used to write data into .txt file...

FileStream fs = new FileStream("E:\\a.txt", FileMode.Create, FileAccess.Write);
StreamWriter write = new StreamWriter(fs);
string a_variable = "more advanced services to mobile or nomadic computing devices";
write.Write(a_variable);
write.Close();
fs.Close();


//This code is used to read data from.txt file...

FileStream fs1 = new FileStream("E:\\a.txt", FileMode.Open);
StreamReader read = new StreamReader(fs1);
string b = read.ReadToEnd();
Console.WriteLine(b);
read.Close();
fs1.Close();

我将从 TextReader [ ^ ]类将保存的数据返回到程序中.

或者，根据应用程序中可用的数据， FileStream [ ^ ]可能就是您想要的.

I''d start with the TextWriter[^] class. As soon as you have successfully written a file, you can proceed to the TextReader[^] class to get the saved data back into your program.

Or, depending on what data you have available in your application, FileStream[^] could be what you''re after.
