VB.Net - FileInfo.IsReadOnly is not returning that a file has been marked as ReadOnly

I'm trying to check and see if a file has been marked as Read only.  If it is Read Only, then I want to change to not be Read Only.  However, the program is not seeing that the IsReadOnly property = True.  It always thinks that IsReadOnly = false.  Am I doing something wrong?

I'm using .Net Framework 3.5.
Dim objFile as New FileInfo(full file path)
If objFile.IsReadOnly = True Then
	objFile.IsReadOnly = False
End If

code seems correct, are you sure that the file you check is readOnly really?
UniqueincAuthor Commented:
Yes, by 2 means:

1. I view the file's properties in Windows Explorer and see that it is marked as Read Only.

2. My code that follows the afore mentioned lines tries to modify the contents of the file and fails with a "The file is read only and cannot be modifed" (not exact quote) error.
What is the way you are opening file for writing?
Are you sure you don't use FileAccess.Read?

I'm looking for an exe file so that I can modify the connection string property in it's app.config file.
If UCase(objFile.Extension) = ".EXE" Then
	If File.Exists(objFile.FullName + ".config") Then
		Dim appconfig As System.Configuration.Configuration = ConfigurationManager.OpenExeConfiguration(objFile.FullName)
		Dim csSection As ConnectionStringsSection = appconfig.ConnectionStrings
		Dim csCollection As ConnectionStringSettingsCollection = csSection.ConnectionStrings
		Dim cs As ConnectionStringSettings = csCollection(0)
		cs.LockItem = False
		cs.ConnectionString = newConnectionString
	End If
End If

Never mind.  I figured out my problem.  I was only setting the IsReadOnly =False prop for the exe file and I was settings it the app.config file also.

Once I did that, it is working fine.  Thanks for helping me think this through!
