How to get the file name of a file in VB?

Question

I make a search program for searching a list of files in a computer and then copy the file into a store folder. The file name could be "*11*2.txt" As long as the program find this pattern, it should copy to the store folder. The problem is that I don't know the exactly name of the file before the search and I don't want to rename the file, I don't know how to save the file. Please help

I use the following to find the file, which does its work

Public Sub DirSearch(ByVal sDir As String, ByVal FileName As String)
    Dim To_Path As String
    To_Path = Form1.TextBox5.Text
    For Each foundFile As String In My.Computer.FileSystem.GetFiles(sDir, FileIO.SearchOption.SearchAllSubDirectories, FileName)
        Copy2Local(foundFile, To_Path)
    Next
End Sub

Here is the current version of the Copy2Local (Note: it is not working right)

    Public Sub Copy2Local(ByVal Copy_From_Path As String, ByVal Copy_To_Path As String)
    ' Specify the directories you want to manipulate.

    Try
        Dim fs As FileStream = File.Create(Copy_From_Path)
        fs.Close()


        ' Copy the file.
        File.Copy(Copy_From_Path, Copy_To_Path)
    Catch

    End Try
End Sub

First, you should check if ToPath is a valid directory since it's coming from a TextBox:

Dim isValidDir = Directory.Exists(ToPath)

Second, you can use Path.Combine to create a path from separate (sub)directories or file-names:

Dim copyToDir = Path.GetDirectoryName(Copy_To_Path)
Dim file = Path.GetFileName(Copy_From_Path)
Dim newPath = Path.Combine(copyToDir, file)
