Примеры

Следующий пример открывает или создает файл, определяет его полный путь, а также определяет и отображает все содержимое каталога.The following example opens or creates a file, determines its full path, and determines and displays the full contents of the directory.

using namespace System;
using namespace System::IO;
int main()
{
   
   // Open an existing file, or create a new one.
   FileInfo^ fi = gcnew FileInfo( "temp.txt" );
   
   // Determine the full path of the file just created.
   DirectoryInfo^ di = fi->Directory;
   
   // Figure out what other entries are in that directory.
   array<FileSystemInfo^>^fsi = di->GetFileSystemInfos();
   Console::WriteLine( "The directory '{0}' contains the following files and directories:", di->FullName );
   
   // Print the names of all the files and subdirectories of that directory.
   Collections::IEnumerator^ myEnum = fsi->GetEnumerator();
   while ( myEnum->MoveNext() )
   {
      FileSystemInfo^ info = safe_cast<FileSystemInfo^>(myEnum->Current);
      Console::WriteLine( info->Name );
   }
}
//This code produces output similar to the following; 
//results may vary based on the computer/file structure/etc.:
//
//The directory 'C:\Visual Studio 2005\release' contains the following files 
//and directories:
//fileinfodirectory.exe
//fileinfodirectory.pdb
//newTemp.txt
//
using System;
using System.IO;

public class DirectoryTest 
{
    public static void Main() 
    {

        // Open an existing file, or create a new one.
        FileInfo fi = new FileInfo("temp.txt");

        // Determine the full path of the file just created.
        DirectoryInfo di = fi.Directory;

        // Figure out what other entries are in that directory.
        FileSystemInfo[] fsi = di.GetFileSystemInfos();

        Console.WriteLine("The directory '{0}' contains the following files and directories:", di.FullName);

        // Print the names of all the files and subdirectories of that directory.
        foreach (FileSystemInfo info in fsi)
            Console.WriteLine(info.Name);
    }
}
//This code produces output similar to the following; 
//results may vary based on the computer/file structure/etc.:
//
//The directory 'C:\Visual Studio 2005\release' contains the following files
