c# - 多个文件，同名

Question

我正在尝试保存几个同名的文件。我想做一些名字做这样的事情:file.extension file[1].extension file[2].extension 我试过这个 http://www.naspinski.net/post/Saving-multiple-files-of-the-same-name.aspx但它对我不起作用。

这里有一些代码要看(不是全部，只是相关部分)，

        {
            string thepathoflife = Path.GetFullPath(file);
            //CreatetheFolder(file)
            string filetocopy = file;
            object bob = file.Clone();
            string bobby = bob.ToString();
            string location = file;
            bool b = false;
            string extension = Path.GetExtension(file);
            string thenameofdoom = Path.GetFileNameWithoutExtension(file);
            string filename = Path.GetFileName(file);
            ////bobby.Move(@"\\TEST12CVG\Public\Posts\Temporaryjunk" + filename);
            // string oldlocation = filename+extension;

            if (extension == ".pst" ||
              extension == ".tec" ||
              extension == ".pas" ||
              extension == ".snc" ||
              extension == ".cst" ||
              extension == ".xml")
            {
                b = true;
            }

            if (thenameofdoom == "Plasma" ||
              thenameofdoom == "Oxygas" ||
              thenameofdoom == "plasma" ||
              thenameofdoom == "oxygas" ||
              thenameofdoom == "Oxyfuel" ||
              thenameofdoom == "oxyfuel")
            {
                b = false;
            }


            if (b == true)
            // System.IO.File.WriteAllText(newlocation, bobby);
            {
                //string rootpath = (@"\\sigmatek.net\Documents\Customers\A");
                var findLevel = 6;
                var path = @thepathoflife;
                var levels = path.Split(Path.DirectorySeparatorChar);
                var second = levels.Length > findLevel ? levels[findLevel] : null;

                Directory.CreateDirectory(@"\\TEST12CVG\Public\Posts\Test\" + thenameofdoom);
                string newlocation = (@"\\TEST12CVG\Public\Posts\Test\" + thenameofdoom);
                string newPath = System.IO.Path.Combine(newlocation, second);
                System.IO.Directory.CreateDirectory(newPath);
                string newlocationb = Path.GetFullPath(newPath);

                    string newb = System.IO.Path.Combine(newlocationb, filename);

                        while (File.Exists(newb))
                            {
                               int number = 1;
                               bool found = false;
                               do
                               {
                                   string candidate = newb.Replace(extension, "[" + number++ + "]"+ extension);
                                   if (!File.Exists(candidate)) found = true;

                                {
                                    File.Copy(thepathoflife, candidate);
                              }
                                   // Candidate has a valid file name


                               }
                               }
                    //File.Move(@"\\TEST12CVG\Public\Posts\Test\", @"\\TEST12CVG\Public\Posts\Test\" + thenameofdoom + second);
                    System.Console.WriteLine("Success: " + filename + "--" + thepathoflife);
                    b = false;

这超出了我的想象。此外，如果“.extension”出现在文件名中的某处而不是末尾，这将中断(因此使您的字符串处理比示例代码更智能)。如果需要，您可以使用 Path.GetExtension(path)

获取扩展

if (File.Exists(fn))
{
   int number = 1;
   bool found = false;
   do
   {
       string candidate = fn.Replace(".extension", "[" + number++ + "].extension");
       if (!File.Exists(candidate)) found = true;
   }
   // Candidate has a valid file name
}
