I want to make a file as access denied. Example: I have a file name called "testing.txt" inside C Drive (@"C:\\Test\testing.txt"). Now I want to make this file as Access Denied, it means no one should not able to access it. By clicking (Right button --> Properties --> Securities) I can make it access denied, but here my question is how can I make it access denied through coding.

If you want the file accessible by no-one - delete it!!! :-)

No I don't want to delete, that file should be there, and by clicking on another button that file should be accessible.

It was a joke!
There is a FileSecurity class in .NET (http://msdn.microsoft.com/en-us/library/system.security.accesscontrol.filesecurity(v=vs.110).aspx). You may use it to remove all ACL entries except yours...
