With so little effort on your side, it doesn't feel comfortable to answer in detail. Look here: https://msdn.microsoft.com/en-us/library/system.io%28v=vs.110%29.aspx.

This is more than enough to do it all on your own, not even asking about any detail. The documentation is crystal clear.

创建文本文件可以通过Stream完成作家。

StreamWriter sw = new StreamWriter（@myFile.txt）;

sw.WriteLine（some text）;

sw.Close（）;



阅读文本文件可以使用StreamReader或命名空间System.IO来完成;



StreamReader sr = new StreamReader（@myFile.txt）;

string text = sr.ReadLine（）;

label1.Text = text;

或

String text = System.IO .File.ReadAllLines（@myFile.txt）;

label1.Text = text;



要删除文本文件，请使用System。 IO.File

System.IO.File.Delete（@myFile.txt）;

Creating text files can be done with Stream Writer.
StreamWriter sw = new StreamWriter(@"myFile.txt");
sw.WriteLine("some text");
sw.Close();

Reading text files can be done with StreamReader or with the namespace System.IO;

StreamReader sr = new StreamReader(@"myFile.txt");
string text = sr.ReadLine();
label1.Text = text;
Or
String text = System.IO.File.ReadAllLines(@"myFile.txt");
label1.Text = text;

To delete text files use System.IO.File
System.IO.File.Delete(@"myFile.txt");
