FileInfo.Directory 属性

定义

获取父目录的实例。Gets an instance of the parent directory.

public:
 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

属性值

表示此文件父目录的 DirectoryInfo 对象。A DirectoryInfo object representing the parent directory of this file.

异常

指定的路径无效,例如位于未映射的驱动器上。The specified path is invalid, such as being on an unmapped drive.

调用方没有所要求的权限。The caller does not have the required permission.

示例

下面的示例将打开或创建一个文件, 确定其完整路径, 并确定并显示该目录的完整内容。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
//fileinfodirectory.exe
//fileinfodirectory.pdb
//newTemp.txt
//temp.txt

Imports System.IO

Public Class DirectoryTest

    Public Shared Sub Main()
        ' Open an existing file, or create a new one.
        Dim fi As New FileInfo("temp.txt")

        ' Determine the full path of the file just created.
        Dim di As DirectoryInfo = fi.Directory

        ' Figure out what other entries are in that directory.
        Dim fsi As FileSystemInfo() = di.GetFileSystemInfos()

        ' Print the names of all the files and subdirectories of that directory.
        Console.WriteLine("The directory '{0}' contains the following files and directories:", di.FullName)
        Dim info As FileSystemInfo
        For Each info In fsi
            Console.WriteLine(info.Name)
        Next info
    End Sub
End Class

注解

若要获取作为字符串的父目录, 请使用DirectoryName属性。To get the parent directory as a string, use the DirectoryName property.
