Добрый вечер,
Ниже приведен код, который я использовал для чтения файлов и папок с диска и т. Д.
Public Class LoadingBox
Public counter As ULong
Public OpenRecords As New Dictionary(Of String, MainWindow.records)
Public Path As String
Public Diskname As String
Private WithEvents BKWorker As New BackgroundWorker()
Public Sub New(ByVal _Path As String, ByVal _Diskname As String)
' This call is required by the designer.
InitializeComponent()
' Add any initialization after the InitializeComponent() call.
Path = _path
Diskname = _diskname
End Sub
Private Sub GetStructure(ByVal tempdir As String, ByVal ParentID As String, ByVal DiskName As String)
Dim maindir As DirectoryInfo = My.Computer.FileSystem.GetDirectoryInfo(tempdir)
For Each Dir As DirectoryInfo In maindir.GetDirectories
Try
Dim d As New MainWindow.records
d.Filename = Dir.Name
d.Folder = True
d.Rowid = Date.UtcNow.ToString() + counter.ToString()
d.Size = 0
d.ParentID = ParentID
d.DiskName = DiskName
d.DateCreated = Dir.CreationTimeUtc
d.DateModified = Dir.LastWriteTimeUtc
OpenRecords.Add(d.Rowid, d)
'Label1.Content = "Processing: " + Dir.FullName
BKWorker.ReportProgress(0, Dir.FullName)
counter = counter + 1
GetStructure(Dir.FullName, d.Rowid, DiskName)
Catch ex As Exception
End Try
Next
For Each fil As FileInfo In maindir.GetFiles
Try
Dim d As New MainWindow.records
d.Filename = fil.Name
d.Folder = False
d.Rowid = Date.UtcNow.ToString() + counter.ToString()
d.Size = fil.Length
d.ParentID = ParentID
d.DiskName = DiskName
d.DateCreated = fil.CreationTimeUtc
d.DateModified = fil.LastWriteTimeUtc
OpenRecords.Add(d.Rowid, d)
'Label1.Content = "Processing: " + fil.FullName
BKWorker.ReportProgress(0, fil.FullName)
counter = counter + 1
Catch ex As Exception
End Try
Next
End Sub
Private Sub Window_Loaded(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs) Handles MyBase.Loaded
counter = 0

End Sub

'Throw New NotImplementedException
MessageBox.Show("Completed")
Me.Close()
End Sub
End Class
Однако проблема в том, что фоновый поток можетчитать файлы очень быстро, но поток пользовательского интерфейса не может поддерживать скорость, не могли бы вы посоветовать мне, как я могу решить эту проблему.
