// Builder.cs -- Demonstrates manipulating a string read as a line from a file
// Compile this program with the following command line:
// C:>csc Builder.cs
//
namespace nsBuilder
{
using System;
using System.Text;
using System.IO;
public class Builder
{
static public int Main ()
{
// Create a stream object and open the input file
FileStream istream;
try
{
istream = new FileStream ("sample.txt", FileMode.Open, FileAccess.Read);
}
catch (Exception)
{
Console.WriteLine ("Could not open sample.txt for reading");
return (-1);
}
// Associate a reader with the stream
StreamReader reader = new StreamReader (istream);
// Declare a new StringBuilder
StringBuilder strb = new StringBuilder ();
// Counter for the lines
int Lines = 0;
while (reader.Peek() > 0)
{
++Lines;
// Clear out the string builder
strb.Length = 0;
// Read a line from the file
string str = reader.ReadLine();
// Split the line into words
string [] Data = str.Split (new char [] {' '});
// Build the output line to show line, word and character count
strb.AppendFormat ("Line {0} contains {1} words and {2} characters:\r\n{3}", Lines, Data.Length, str.Length, str);
// Write the string to the console
Console.WriteLine (strb.ToString ());
}
istream.Close ();
return (0);
}
}
}
//File: sample.txt
