Question

如何用用C#代码如何实现删除.CS文件中复制到的行号。刚刚入门，这种程序不怎么会编，求大神指导
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.IO;
using System.Text.RegularExpressions;

namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
string path = ( @"F:\Game\");

    System.IO.DirectoryInfo di = null;
    FileInfo[] ff = null;
    try
    {
        di = new System.IO.DirectoryInfo(path);
        ff = di.GetFiles("*.cs");
    }
    catch (Exception e)
    {
        Console.WriteLine(e.ToString());
    }
    string ss = Regex.Replace(path, @"^\s*\d+", "", RegexOptions.Multiline);
    if (di.Exists)
    {
        foreach (FileInfo temp in ff)
        {
            FileStream fs = temp.OpenRead();                  
            temp.IsReadOnly = false;
            StreamReader sr = new StreamReader(fs, System.Text.Encoding.GetEncoding(936), true);
            ss += sr.ReadToEnd();
        }
    }
    else
    {
        Console.WriteLine("不存在该文件夹");
    }            
    File.AppendAllText(@"F:\game\reader.txt", ss + "\r\n" );
    Console.WriteLine("Thanks!");
    Console.ReadKey();
}

}
}

Answer 1

用IO读取cs文件内容，正则替换下。。不懂你行号在哪，如果是在每行开始，可以用这个正则替换

 \s*\d+

主要是想把复制过来的代码前面的序号删除吧？把代码复制到xls电子表格里，你多试试，轻松就可以解决问题了，在电子表格里序号在单独一列，再复制时不选它就行了。希望能帮助你。

    static void Main(string[] args)
    {
        string path = (@"F:\Game\");
        Regex rx = new Regex(@"^\s*\d+", RegexOptions.Multiline);
        string[] files = Directory.GetFiles(path, "*.cs");
        foreach(string file in files)
        {
            string content = File.ReadAllText(file, Encoding.GetEncoding(936));//注意如果你的cs文件编码是utf-8，编码要改为Encoding.UTF8，要不有中文乱码

            content = rx.Replace(content, "");
            File.AppendAllText(@"F:\game\reader.txt", content + "\r\n", Encoding.GetEncoding(936));//注意如果你的cs文件编码是utf-8，编码要改为Encoding.UTF8，要不有中文乱码
            //File.WriteAllText(file, content, Encoding.GetEncoding(936));///直接替换原来文件内容就好了，不过你最好是先备份之前的cs文件
        }

        Console.WriteLine("Thanks!");
        Console.ReadKey();
    }
