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 " );
}
}

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 " );
}
}
