The following code prompts users to open a new workbook in Microsoft Office Excel. It sets properties to allow multi-selection, clears the list of available filters, and adds two new filters. The code then calls the Execute method of the FileDialog object to open the requested files.

Example

With Me.Application.FileDialog(Microsoft.Office.Core.MsoFileDialogType.msoFileDialogOpen)

    .AllowMultiSelect = True
    .Filters.Clear()
    .Filters.Add("Excel Files", "*.xls;*.xlw")
    .Filters.Add("All Files", "*.*")

    If .Show = True Then
        .Execute()
    End If 
End With

Microsoft.Office.Core.FileDialog fd = 
    this.Application.get_FileDialog(Microsoft.Office.Core.MsoFileDialogType.msoFileDialogOpen);

fd.AllowMultiSelect = true; 
fd.Filters.Clear(); 
fd.Filters.Add("Excel Files", "*.xls;*.xlw", missing); 
fd.Filters.Add("All Files", "*.*", missing); 

if (fd.Show() != 0)
{
    fd.Execute();
}
