Code:
override public void getUserName()
{
try
{
file = new FileStream(@"C:\username.txt", FileMode.Append, FileAccess.Write);
// Create a new stream to write to the file
sw = new StreamWriter(file);
Console.WriteLine("Please Enter your username :");
s = Console.ReadLine();
Counter = Counter + 1;
sw.WriteLine(Counter+"."+s);
//sw.Write(sw.NewLine);
Console.WriteLine("Please Enter your Phone Number :");
String ph = Console.ReadLine();
int i = Int32.Parse(ph);
sw.WriteLine(i);
sw.Write(sw.NewLine);
// Close StreamWriter
sw.Close();
// Close file
file.Close();
}
File username.txt contains
1.haroon
123456
1.shah
78
Please enter username to delete the data: haroon
Now it should delete haroon and 123456.
How this delete functionality can be implemented? Any idea please help
