FileInfo.Directory プロパティ

定義

親ディレクトリのインスタンスを取得します。Gets an instance of the parent directory.

 property System::IO::DirectoryInfo ^ Directory { System::IO::DirectoryInfo ^ get(); };
public System.IO.DirectoryInfo Directory { get; }
member this.Directory : System.IO.DirectoryInfo
Public ReadOnly Property Directory As DirectoryInfo

プロパティ値

このファイルの親ディレクトリを表す DirectoryInfo オブジェクト。A DirectoryInfo object representing the parent directory of this file.

例外

マップされていないドライブにあるなど、指定されたパスが無効です。The specified path is invalid, such as being on an unmapped drive.

呼び出し元に、必要なアクセス許可がありません。The caller does not have the required permission.

次の例では、ファイルを開いたり作成したりして、完全なパスを決定し、ディレクトリの完全な内容を確認して表示します。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 
//and directories:
//TempPE
