使用程序将文件夹名字输出到文本文件中

目地:新建一个mvc的空项目,很多程序集都没有引用,想将默认的程序中的文件包含进新建项目中

　　这需要使用nuget的命令,但是有的不知道其使用的名称,我就新建了一个默认的MVC工程,

　　将新建工程的packages 文件夹下的包名称拿出来执行即可,可是使用的比较多,

反正是放假,写个简陋的不能再简陋的小工具获取下试试

using System.Configuration;
using System.IO;
using System.Text.RegularExpressions;

namespace GetPackageName
{
    class Program
    { 
        static void Main(string[] args)
        { 
            //取得配置文件使用的配置新项目packages地址
            string path = ConfigurationManager.AppSettings["packagePath"] ?? @"C:";
            //根据地址得到相应的目录
            DirectoryInfo dir = new DirectoryInfo(path);
            //简单的验证下,虽然添加了c:默认地址
            if (dir.Exists)
            {
                //得到子文件夹
                var arrayDir = dir.GetDirectories();

                //得到输出文件地址文件流
                FileStream fs = new FileStream(ConfigurationManager.AppSettings["recordPath"]?? @"d:packages.txt", FileMode.OpenOrCreate);
                //创建一个StreamWriter,用来想流中写入文件
                StreamWriter sw = new StreamWriter(fs);

                //对包进行正则匹配,去掉其版本信息
                Regex regex = new Regex(@"(^[a-zA-Z-.]*.)");

                //循环子目录
                foreach (DirectoryInfo item in arrayDir)
                {
                    //匹配包的信息
                    var match = regex.Match(item.Name);
                    //将包名写入到流中
                    sw.Write(string.Format("install-package {0}",match.Groups[1].ToString().Trim('.') + System.Environment.NewLine));
                }
                //将流强制输出
                sw.Flush();
                //关闭写入流
                sw.Close();
                //关闭文件流
                fs.Close();
            }

        }
    }
}

配置文件配置为

  <appSettings>
    <add key ="packagePath" value ="C:UsersxxxxDocumentsvisual studio 2013ProjectsWebMVCPackagepackages"/>
    <add key ="recordPath" value="d:packages.txt"/>
  </appSettings>

其他多的验证啥的都没写,随意耍耍而已

最后的结果 在d:packages.txt 文件中得到
