I have started working on a search in a windows forms app but when I try to run the program I get the following security Exception

"Request for the permission of type 'System.Security.Permissions.FileIOPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed."

Here is my code:

Dim FilePath As String = TextBox1.Text
Dim FileType As String = TextBox2.Text
Dim diContents As New DirectoryInfo(FilePath)
Dim di As FileInfo
Dim filename As String = ListBox1.SelectedIndex
Dim testname As String

For Each di In diContents.GetFiles
Dim dirs() As String = Directory.GetFiles(FilePath & di.Name)
For Each filename In dirs
testname = System.IO.Path.GetFileName(filename)

Dim fileTest As String = testname.Remove(0, (Len(testname) - 3))
If UCase(fileTest) = FileType Then
ListBox1.Items.Add(testname)
End If
Next
Next
End Sub

Just to explain what I am trying to do, I want to enter the file path into the textbox where I want to search for the files. I want to enter the file extension(.txt, .mp3) into a textbox to specific what type of file I am looking for. Once the files are found, add them to the list box on the form. Is this code correct?

This line of code(Dim diContents As New DirectoryInfo(FilePath)) is highlighted when error occurs.

Any ideas?
