WPF hat leider keinen FolderBrowseDialog mehr wie in WinForms. Daher habe ich angefangen diesen nach zubauen. Ich habe jetzt die Version 0.1.0 veröffentlicht (http://wpfdialogs.codeplex.com/), wo der FolderBrowseDialog ein DialogResult hat (wie in WinForms nicht wie WPF-Dialoge) und die Möglichkeit besteht den ausgewählten Pfad auszulesen. Also einfach die Grundfunktionen bereitstellt

{
EDialogResult DialogResult { get; set; }
}
/// <summary>
/// Represents all possible DialogResults (same as in the System.Windows.Forms-namespace)
/// </summary>
public enum EDialogResult : int
{
Abort = 1,
Cancel = 2,
Ignore = 3,
No = 4,
None = 5,
OK = 6,
Retry = 7,
Yes = 8
}
}
