This is a collection of helpers and data binding utillities for WinForms development. Please see the Wiki for latest info.

There's also a separate Nuget package AO.FileSystem that removes the WinForms dependency, and provides several file search methods:

• void EnumFiles (string path, string searchPattern, Func<FileInfo, EnumFileResult> fileFound)
• void EnumDirectories (string path, [ Func<DirectoryInfo, EnumFileResult> starting ], [ Func<DirectoryInfo, EnumFileResult> ending ])
• Task<IEnumerable<FileInfo>> FindFilesAsync (string path, string searchPattern, [ Func<FileInfo, bool> filter ])
• IEnumerable<string> FindFolders (string rootPath, string query, [ int minQueryLength ], [ int maxResults ], [ IProgress progress ], [ CancellationTokenSource cancellationTokenSource ])
• Task<IEnumerable<string>> FindFoldersAsync (string rootPath, string query, [ int minQueryLength ], [ int maxResults ], [ IProgress progress ], [ CancellationTokenSource cancellationTokenSource ])

• string GetCommonPath (IEnumerable fileNames, [ char separator ], [ bool samePathReturnsParent ])
• Dictionary<string, string> UniquifyFiles (IEnumerable fileNames)
• string GetParentFolder (string path)
• string ReplaceExtension (string fileName, string newExtension)
• string EnvironmentPath (SpecialFolder specialFolder, params string[] parts)
