Question

我想将所有文件从当前文件夹复制到其中的另一个文件夹。但不包括.exe和.dll文件。

这是我现在拥有的代码，它将每个文件从当前复制到另一个文件夹。我已经搜索了，并且根据扩展名没有几个要排除的答案，但这不是我想要的。我想根据其名称进行排除，以便以后可以排除更多文件。

string TargetDirectory = @"Copied";
if (Directory.Exists(TargetDirectory))
{
    Directory.Delete(TargetDirectory, true);
}

Directory.CreateDirectory(TargetDirectory);
await Task.Delay(1000);

string SourceDirectory = Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location);

Logger.LogInfo("Creating Backup of the Source Directory...");            
if (Directory.GetFiles(SourceDirectory).Length == 0)
{
     Logger.LogError("No Files found in this directory. " + SourceDirectory);
     return;
}
else
{   
    //Now Create all of the directories         
    foreach (string dirPath in Directory.GetDirectories(SourceDirectory, "*", SearchOption.AllDirectories))
        Directory.CreateDirectory(dirPath.Replace(SourceDirectory, TargetDirectory));

    //Copy all the files & Replaces any files with the same name
    foreach (string newPath in Directory.GetFiles(SourceDirectory, "*.*", SearchOption.AllDirectories)) 
        File.Copy(newPath, newPath.Replace(SourceDirectory, TargetDirectory), true);
}

尝试，应该可以：

    async Task<void> Copy(List<string> ExcludedNamesWithoutExtensions)
    {
        string TargetDirectory = @"Copied";
        if (Directory.Exists(TargetDirectory))
        {
            Directory.Delete(TargetDirectory, true);
        }

        Directory.CreateDirectory(TargetDirectory);

        await Task.Delay(1000);

        string SourceDirectory = Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location);

        Logger.LogInfo("Creating Backup of the Source Directory...");
        if (Directory.GetFiles(SourceDirectory).Length == 0)
        {
            Logger.LogError("No Files found in this directory. " + SourceDirectory);
            return;
        }
        else
        {
            //Now Create all of the directories         
            foreach (string dirPath in Directory.GetDirectories(SourceDirectory, "*", SearchOption.AllDirectories)) Directory.CreateDirectory(dirPath.Replace(SourceDirectory, TargetDirectory));
            //Copy all the files & Replaces any files with the same name
            foreach (string newPath in Directory.GetFiles(SourceDirectory, "*.*", SearchOption.AllDirectories))
            {
                bool CanCopy = true;
                    string[] array = newPath.Split('\\')[newPath.Split('\\').Length - 1].Split('.');
                    string name = array[array.Length - 1];
                foreach (string s in ExcludedNamesWithoutExtensions)
                {
                    if (name != s)
                    {
                         CanCopy = false;
                         break;
                    }
                }
                if (CanCopy)
                        File.Copy(newPath, newPath.Replace(SourceDirectory, TargetDirectory), true);
            }
        }
    }

这应该有效：

      HashSet<string> namesToExclude = new HashSet<string>()
      {
        "bla.dll",
        "blubb.exe"
      };
      string TargetDirectory = @"Copied";
      if (Directory.Exists(TargetDirectory))
      {
        Directory.Delete(TargetDirectory, true);
      }

      Directory.CreateDirectory(TargetDirectory);
      await Task.Delay(1000);

      string SourceDirectory = Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location);

      Logger.LogInfo("Creating Backup of the Source Directory...");            
      if (Directory.GetFiles(SourceDirectory).Length == 0)
      {
        Logger.LogError("No Files found in this directory. " + SourceDirectory);
        return;
      }
      else
      {   
        //Now Create all of the directories         
        foreach (string dirPath in Directory.GetDirectories(SourceDirectory, "*", SearchOption.AllDirectories))
          Directory.CreateDirectory(dirPath.Replace(SourceDirectory, TargetDirectory));

        //Copy all the files & Replaces any files with the same name
        foreach (string newPath in Directory.GetFiles(SourceDirectory, "*.*", SearchOption.AllDirectories))
        {
          if (!namesToExclude.Contains(Path.GetFileName(newPath)))
          {
            File.Copy(newPath, newPath.Replace(SourceDirectory, TargetDirectory), true);
          }

        }
      }

哦，要注意的是，如果根目录中只有目录而没有文件，则您的代码将不会复制，您可能还需要检查目录。子目录也将是一个问题。您可以使用递归来解决此问题。

复制时排除文件
