使用C#将文本文件从ANSI转换为ASCII

using System;
using System.IO;
using System.Text;

namespace AnsiToAsciiConverter
{
    class Program
    {
        static void Main(string[] args)
        {
            string inputFilePath = "input.txt";
            string outputFilePath = "output.txt";

            try
            {
                string inputContent = File.ReadAllText(inputFilePath, Encoding.Default);
                byte[] asciiBytes = Encoding.Convert(Encoding.Default, Encoding.ASCII, Encoding.Default.GetBytes(inputContent));
                string outputContent = Encoding.ASCII.GetString(asciiBytes);
                File.WriteAllText(outputFilePath, outputContent, Encoding.ASCII);

                Console.WriteLine("文件已成功转换！");
            }
            catch (Exception ex)
            {
                Console.WriteLine("转换过程中发生错误：" + ex.Message);
            }
        }
    }
}
