Source:

IsolatedStorageFile.cs

public:
 cli::array <System::String ^> ^ GetDirectoryNames();

public string[] GetDirectoryNames ();

[System.Runtime.InteropServices.ComVisible(false)]
public string[] GetDirectoryNames ();

member this.GetDirectoryNames : unit -> string[]

[<System.Runtime.InteropServices.ComVisible(false)>]
member this.GetDirectoryNames : unit -> string[]

Public Function GetDirectoryNames () As String()

返回

独立存储根处目录的相对路径的数组。 零长度数组指定根处没有任何目录。

属性

ComVisibleAttribute

例外

注解

此方法等效于使用 IsolatedStorageFile.GetDirectoryNames(String) 为搜索模式指定了“*”的方法。

示例

下面的代码示例演示 GetDirectoryNames 了 方法。 有关此示例的完整上下文，请参阅 IsolatedStorageFile 概述。

array<String^>^dirNames = isoFile->GetDirectoryNames( "*" );
array<String^>^fileNames = isoFile->GetFileNames( "*" );

// List directories currently in this Isolated Storage.
if ( dirNames->Length > 0 )
{
   for ( int i = 0; i < dirNames->Length; ++i )
   {
      Console::WriteLine( "Directory Name: {0}", dirNames[ i ] );

   }
}


// List the files currently in this Isolated Storage.
// The list represents all users who have personal preferences stored for this application.
if ( fileNames->Length > 0 )
{
   for ( int i = 0; i < fileNames->Length; ++i )
   {
      Console::WriteLine( "File Name: {0}", fileNames[ i ] );

   }
}

    String[] dirNames = isoFile.GetDirectoryNames("*");
    String[] fileNames = isoFile.GetFileNames("Archive\\*");

    // Delete all the files currently in the Archive directory.

    if (fileNames.Length > 0)
    {
        for (int i = 0; i < fileNames.Length; ++i)
        {
            // Delete the files.
            isoFile.DeleteFile("Archive\\" + fileNames[i]);
        }
        // Confirm that no files remain.
        fileNames = isoFile.GetFileNames("Archive\\*");
    }

    if (dirNames.Length > 0)
    {
        for (int i = 0; i < dirNames.Length; ++i)
        {
            // Delete the Archive directory.
        }
    }
    dirNames = isoFile.GetDirectoryNames("*");
    isoFile.Remove();
}
catch (Exception e)
{
    Console.WriteLine(e.ToString());
}

Dim dirNames As String() = isoFile.GetDirectoryNames("*")
Dim fileNames As String() = isoFile.GetFileNames("*")
Dim name As String

' List directories currently in this Isolated Storage.
If dirNames.Length > 0 Then

    For Each name In dirNames
        Console.WriteLine("Directory Name: " & name)
    Next name
End If

' List the files currently in this Isolated Storage.
' The list represents all users who have personal preferences stored for this application.
If fileNames.Length > 0 Then

    For Each name In fileNames
        Console.WriteLine("File Name: " & name)
    Next name
End If

注解

通配符只能位于 的最后一个 searchPattern元素中。 例如，“directory1/*etc*”是有效的搜索字符串，但“*etc*/directory”不是。

searchPattern “Project\Data*”将提供 Project 的所有子目录，从独立存储范围中的数据开始。 searchPattern “*”将返回位于根目录中的所有目录。 有关搜索字符串条件的完整说明，请参阅 Directory 类。

有关获取文件名的信息，请参阅 GetFileNames 方法。

如何：在独立存储中查找现有文件和目录示例演示了 方法的使用GetDirectoryNames。
