如何将DirectoryInfo句柄转换为用户定义的类? [英] How can I convert a DirectoryInfo handle to a user-defined class?

问题描述

我正在用Visual c ++进行一个名为文件搜寻器"的项目.它将简单地索引文件中指定目录的所有文件.用户可以通过扩展名，名称等在此c ++文件中搜索特定文件.

现在，我想将所有文件名和目录放入我创建的类的对象中.我发现此代码很有帮助:

I am working on a project named "file crawler" in visual c++. It will simply index all the files of a specified directory in a file. The user can search this c++ file for a particular file through extension, name etc.

Right now, I want to get all the file names and directories into an object of my created class. I found this code helpful:

using namespace System;
using namespace System::IO;

int main()
{

   // Make a reference to a directory.

DirectoryInfo^ di = gcnew DirectoryInfo( "d:\\" );

   // Get a reference to each file in that directory.

array<FileInfo^>^fiArr = di->GetFiles();

   // Display the names of the files.

Collections::IEnumerator^ myEnum = fiArr->GetEnumerator();

 while ( myEnum->MoveNext() )
   {
      FileInfo^ fri = safe_cast<FileInfo^>(myEnum->Current);

 Console::WriteLine( fri->Name );
   }
}

问题在于此代码使用文件信息句柄，并且我不知道如何将所有这些数据传输到将成为目录类(我的类)中指针的对象.
我的课是这样的:

The problem is that this code uses the file info handle and I don''t know how to transfer all this data to an object that will be a pointer in a directory class (my class).

My class is like this:

class directories
{
    //data members
    ffile *file;  //file is my class
    ddirectory *sdirectory //ddirectory will hold the names of subdirectories

    string path;
};

我还需要以下说明:

I also need the explanation of:

Collections::IEnumerator^ myEnum = fiArr->GetEnumerator();

我正在毕业的第二年.请给我一些建议.我有20天的时间来完成此项目.

I am doing second year of graduation. Please suggest some ideas to me. I have 20 days to complete this project.

推荐答案

我相信您可能会发现以下有趣的内容:
http://www.boost.org/doc/libs/1_46_0/libs/filesystem/v3/doc/tutorial.html [ ^ ]-它甚至可以在其他操作系统上运行

您也可以使用
http://www.boost.org/doc/libs/1_46_0/libs/regex/doc/html/index.html [ ^ ]可以促进非常高级的搜索条件.

上面的内容比使用C ++/CLI更像是一种真正的" C ++方法，但是，如果您想使用C ++/CLI，则以下文章应该可以帮助您解决C ++/CLI中的问题:

也有产品文档 [布鲁斯·埃克尔(Bruce Eckel)在C ++第二版中的思考 [

I believe you may find this interesting:

You can also use
http://www.boost.org/doc/libs/1_46_0/libs/regex/doc/html/index.html[^] to facilitate quite advanced search criteria.

The above is more of a "real" C++ approach than using C++/CLI, but if you want to use C++/CLI the following articles should help you to solve your problem in C++/CLI:

Best Practices for Writing Efficient and Reliable Code with C++/CLI[^]

There is also the product documentation[^]

If you are new to C++, take a look at:
Thinking in C++ 2nd Edition by Bruce Eckel[^]

The links will allow you to solve your problem, but you''re the one who is going to create your solution.

Good luck :)
