[RESOLVED]VB.NET - Search for specific file in Directory and subdirectories

[Stephen_Hawking]

I'm trying to program a program that looks for a specific file in a folder. If it finds the file, it has to start it

My not working code

  Dim directory = "C:\Users\Multi\Desktop\"


        For Each filename As String In IO.Directory.GetFiles(directory, "*.exe", IO.SearchOption.AllDirectories)

            If filename = "test.exe" Then

                Process.Start(filename)

            End If
        Next

Could someone give me a help?

Thanks in advance

That code is not working because 'filename' contains the full path of the file, not just the name. You shouldn't need that pointed out because you should have looked for yourself.

Also, if you want a file named "test.exe" then why look for "*.exe"? Why not look for "test.exe"? If you're going to do that though, there's no point calling Directory.GetFiles at all. You should just call File.Exists.

Dim filePath = "C:\Users\Multi\Desktop\test.exe"
 
If File.Exists(filePath) Then
    Process.Start(filePath)
End If

Ah, I just noticed that you are searching subfolders too. In that case, you would need to stick with Directory.GetFiles:

Dim folderPath = "C:\Users\Multi\Desktop"
Dim filePath = Directory.GetFiles(folderPath,
                                  "test.exe",
                                  SearchOption.AllDirectories).FirstOrDefault()
 
If filePath IsNot Nothing Then
    Process.Start(filePath)
End If

Just be aware that, theoretically at least, there could be multiple files with that name in different folders. If you wanted to start each one of multiple then you can do this:

Dim folderPath = "C:\Users\Multi\Desktop"
 
For Each filePath In Directory.GetFiles(folderPath,
                                        "test.exe",
                                        SearchOption.AllDirectories)
    Process.Start(filePath)
Next

Maybe I explained wrong. "Test.exe" could be everywhere in the folder Desktop. What I'm trying to di is, search in all folders for the file "test.exe"

See my second response. I missed that the first time around.
