Convert the UTF-16 encoded source string to ASCII

using System;
using System.IO;
using System.Text;
class MainClass
{
    public static void Main() 
    {        
        using (StreamWriter output = new StreamWriter("output.txt")) 
        {
            string srcString = "Area = \u03A0r^2";
            byte[] asciiString = Encoding.ASCII.GetBytes(srcString);
            output.WriteLine("ASCII  Bytes: {0}", 
                BitConverter.ToString(asciiString));
        }
    }
}

Encodings: Encoding.ASCII

using System;
using System.Collections;
using System.Collections.Generic;
using System.IO;
using System.Reflection;
using System.Resources;
using System.Text;
using System.Threading;
using System.Globalization;
public class MainClass
{
    public static void Main()
    {
        Encoding ascii = Encoding.ASCII;
        Console.WriteLine(ascii);
    }
}

System.Text.ASCIIEncoding

Write the ASCII encoded byte arrays

using System;
using System.IO;
using System.Text;
class MainClass
{
    public static void Main() 
    {        
        using (StreamWriter output = new StreamWriter("output.txt")) 
        {
            string srcString = "Area = \u03A0r^2";
            byte[] asciiString = Encoding.ASCII.GetBytes(srcString);
            output.WriteLine("ASCII  Bytes: {0}", 
                BitConverter.ToString(asciiString));
        }
    }
}
