文本文件的基本操作

作者：ghost 来源：CSDN 2007年9月24日

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();
    }
}

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");
    }
}
