Windows Downloads Klasörüne Erişim

Selam,

Geçenlerde windowsun downloads ve resimler klasörüne erişmem gerekti ve path bilgisini nasıl bulurum diye bir araştırma yaptım.
Windows ile gelen standart klasörlerin birer unique id’si mevcut bu idleri kullanarak windows yüklü tüm cihazlarda erişim sağlayabilirsiniz.

//Sample:

string downloadsPath = KnownFolders.GetPath(KnownFolder.Downloads);


//Class:

using System;
using System.Runtime.InteropServices;

///
/// Class containing methods to retrieve specific file system paths.
///

public static class KnownFolders
{
private static string[] _knownFolderGuids = new string[]
{
"{56784854-C6CB-462B-8169-88E350ACB882}", // Contacts
"{B4BFCC3A-DB2C-424C-B029-7FE99A87C641}", // Desktop
