Browse File on VB.NET

You can do this by using the OpenFileDialog class that is defined in Windows.Forms class. First, you need to add reference to System.Windows.Form.dll library and call using Imports.System.Windows.Forms before using the class.

In this sample code, I'm using OpenFileDialog class to browse a file.

Private fdlg As OpenFileDialog = New OpenFileDialog()
Private fdlg.Title = "Open File"
Private fdlg.InitialDirectory = "E:\"
Private fdlg.Filter = "All files (*.*)|*.*|All files (*.*)|*.*"
Private fdlg.FilterIndex = 2
Private fdlg.RestoreDirectory = True
If fdlg.ShowDialog() = DialogResult.OK Then
textBox1.Text = fdlg.FileName
End If

Title member let you set the title of the open dialog.
Filter member let you set a filter for types of files to open.
FileName member gives you the name of the selected file.
