1、建立一个文本文件
public class FileClass
{
 public static void Main()
 {
 WriteToFile();
 }
 static void WriteToFile()
 {
 StreamWriter SW;
 SW=File.createText("c:\MyTextFile.txt");
 SW.WriteLine("God is greatest of them all");
 SW.WriteLine("This is second line");
 SW.Close();
 Console.WriteLine("File created SucacessFully");
 }
}

2、读文件
public class FileClass
{
 public static void Main()
 {
 ReadFromFile("c:\MyTextFile.txt");
 }
 static void ReadFromFile(string filename)
 {
 StreamReader SR;
 string S;
 SR=File.OpenText(filename);
 S=SR.ReadLine();
 while(S!=null)
 {
 Console.WriteLine(S);
 S=SR.ReadLine();
 }
 SR.Close();
 }
}
3、追加操作
public class FileClass
{
 public static void Main()
 {
 AppendToFile();
 }
 static void AppendToFile()
 {
 StreamWriter SW;
 SW=File.AppendText("C:\MyTextFile.txt");
 SW.WriteLine("This Line Is Appended");
 SW.Close();
 Console.WriteLine("Text Appended Successfully");
 }
}
